Background Malnutrition is a serious concern in older populations. Simple screening approaches are needed to identify signs of early nutritional risk in older people, to allow intervention before overt malnutrition develops, along with the poorer health outcomes associated with it, such as sarcopaenia and frailty. The main aim of this study was to compare nutrition risk scores, calculated from the DETERMINE Checklist (‘Determine Your Nutritional Health’, also known as the Nutrition Screening Initiative Checklist), with physical function variables in a group of community-dwelling older adults. Another aim was to assess the prevalence of nutrition risk using the DETERMINE and the MUST (Malnutrition Universal Screening Tool). Methods Participants of the Hertfordshire Cohort Study (HCS) were recruited and visited at home by a trained researcher. Self-reported physical function was assessed using the SF-36 PF (Short Form-36 Physical Function) scale. The Short Physical Performance Battery (SPPB) was performed, which included the assessment of gait speed, chair rise time and standing balance. Handgrip strength was measured using a Jamar dynamometer. Frailty was assessed according to the presence of at least three of the following Fried frailty criteria: unintentional weight loss, weakness, self-reported exhaustion, slow gait speed and low physical activity. Nutrition risk scores were calculated from the DETERMINE checklist (range 0–21). Nutritional risk was also assessed using the MUST. Analyses were adjusted for sex, age, age left education and number of comorbidities. Results In the study, 176 participants (94 men and 82 women), median age 83.3 (IQR 81.5–85.7) years, were assessed. Almost half (47%) scored either ‘moderate’ (score 3–5) or ‘high’ (score ≥ 6) nutritional risk (9% were at high risk), using the DETERMINE checklist, whereas 8% were at risk using the MUST. Higher nutrition risk scores, calculated from DETERMINE, were associated with poorer self-reported physical function (difference in SF-36 PF score: − 0.36, 95% CI (− 0.60, − 0.12) SD per unit increase in nutrition risk score, P = 0.004) and higher odds of being frail (odds ratio Fried frailty: 2.23, 95% CI (1.15, 4.33), P = 0.017). There were no significant associations between DETERMINE nutrition risk scores and the other variables examined. Conclusion Cross-sectional associations between higher nutrition risk scores, assessed from the DETERMINE checklist, and poorer self-reported physical function and greater likelihood of frailty suggest that this screening tool may have utility for screening older populations. Prospective studies are required to explore the ability of the tool to predict poor physical function and frailty, though these data suggest it has potential for early, simple detection of nutritional problems in community-living older adults.

Background Social relationships play a fundamental role in individuals’ lives and health, and social isolation is prevalent among older people. Chronic non-communicable diseases (NCDs) and frailty are also common in older adults. Aims To examine the association between number of NCDs and social isolation in a cohort of community-dwelling older adults in the UK, and to consider whether any potential association is mediated by frailty. Methods NCDs were self-reported by 176 older community-dwelling UK adults via questionnaire. Social isolation was assessed using the six-item Lubben Social Network Scale. Frailty was assessed by the Fried phenotype of physical frailty. Results The median (IQR) age of participants in this study was 83.1 (81.5–85.5) years for men and 83.8 (81.5–85.9) years for women. The proportion of socially isolated individuals was 19% in men and 20% in women. More women (18%) than men (13%) were identified as frail. The number of NCDs was associated with higher odds of being isolated in women (unadjusted odds ratio per additional NCD: 1.65, 95% CI 1.08, 2.52, p = 0.021), but not in men, and the association remained robust to adjustment, even when accounting for frailty (OR 1.85, 95% CI 1.06, 3.22, p = 0.031). Discussion Number of self-reported NCDs was associated with higher odds of social isolation in women but not in men, and the association remained after considering frailty status. Conclusions Our observations may be considered by healthcare professionals caring for community-dwelling older adults with multiple NCDs, where enquiring about social isolation as part of a comprehensive assessment may be important.

Women make up a growing proportion of the workforce and therefore many women experience menopause while in paid employment. We explored the prevalence of menopausal symptoms, the relationship between symptoms and coping with work and the risk factors associated with struggling at work during the menopause. The Health and Employment After Fifty (HEAF) community-based cohort of people aged 50–64 years was incepted 2013–2014 to study health and work. In 2019, female participants were asked to complete a questionnaire about their menopausal symptoms, and effect of those symptoms on their ability to cope at work. 409 women were eligible for inclusion. The commonest symptoms were vasomotor (91.7%); trouble sleeping (68.2%); psychological (63.6%) and urinary (49.1%). The prevalence of reporting symptoms was similar no matter which type of occupation women were performing at the time. Around one-third of women reported moderate/severe difficulties coping at work because of menopausal symptoms. Risk factors for difficulties coping at work included: financial deprivation, poorer self-rated health, depression, and adverse psychosocial occupational factors but not physical demands. More awareness is needed amongst employers in all sectors but women with financial difficulties and those with jobs in which they feel insecure, unappreciated, or dissatisfied are at greatest risk.

Self-perceived risk of fracture (SPR) is associated with fracture independent of FRAX calculated risk. To understand this better we considered whether lifestyle factors not included in the FRAX algorithm and psychosocial factors (social isolation, self-efficacy, or mental health status) explain the relationship between SPR and fracture.We studied 146 UK community-dwelling older adults from the Hertfordshire Cohort Study. SPR ranked as 'lower', 'similar' and 'higher' relative to others of the same age, was assessed by questionnaire. Social isolation was assessed using the six-item Lubben Social Network Scale; self-efficacy was assessed using a shortened General Self-Efficacy Scale (GSE); mental health status was assessed using the anxiety/depression item from the EuroQoL questionnaire. SPR in relation to previous self-reported fracture was examined using logistic regression.Among participants of median age 83.4 (IQR 81.5-85.5) years, SPR was lower for 54.1% of participants, similar for 30.8%, and higher for 15.1%; 74.7% reported no previous fractures. Greater SPR was associated with increased odds of previous fractures when adjusting for sex and age only (OR 1.72, 95% CI 1.03-2.87, per higher band of SPR). While further individual adjustment for social isolation (1.73, 1.04-2.89), self-efficacy (1.71, 1.02-2.85), or mental health (1.77, 1.06-2.97) did not attenuate the relationship, individual adjustment for diet quality and number of comorbidities did.Adjustment for social isolation, self-efficacy or mental health status did not attenuate the relationship between SPR and fracture. By contrast, lifestyle factors not included in FRAX, such as diet quality, did attenuate relationships, suggesting a possible future area of investigation.

BackgroundTraditional analysis of High Resolution peripheral Quantitative Computed Tomography (HR-pQCT) images results in a multitude of cortical and trabecular parameters which would be potentially cumbersome to interpret for clinicians compared to user-friendly tools utilising clinical parameters. A computer vision approach (by which the entire scan is ‘read’ by a computer algorithm) to ascertain fracture risk, would be far simpler. We therefore investigated whether a computer vision and machine learning technique could improve upon selected clinical parameters in assessing fracture risk.MethodsParticipants of the Hertfordshire Cohort Study (HCS) attended research visits at which height and weight were measured; fracture history was determined via self-report and vertebral fracture assessment. Bone microarchitecture was assessed via HR-pQCT scans of the non-dominant distal tibia (Scanco XtremeCT), and bone mineral density measurement and lateral vertebral assessment were performed using dual-energy X-ray absorptiometry (DXA) (Lunar Prodigy Advanced). Images were cropped, pre-processed and texture analysis was performed using a three-dimensional local binary pattern method. These image data, together with age, sex, height, weight, BMI, dietary calcium and femoral neck BMD, were used in a random-forest classification algorithm. Receiver operating characteristic (ROC) analysis was used to compare fracture risk identification methods.ResultsOverall, 180 males and 165 females were included in this study with a mean age of approximately 76 years and 97 (28 %) participants had sustained a previous fracture. Using clinical risk factors alone resulted in an area under the curve (AUC) of 0.70 (95 % CI: 0.56–0.84), which improved to 0.71 (0.57–0.85) with the addition of DXA-measured BMD. The addition of HR-pQCT image data to the machine learning classifier with clinical risk factors and DXA-measured BMD as inputs led to an improved AUC of 0.90 (0.83–0.96) with a sensitivity of 0.83 and specificity of 0.74.ConclusionThese results suggest that using a three-dimensional computer vision method to HR-pQCT scanning may enhance the identification of those at risk of fracture beyond that afforded by clinical risk factors and DXA-measured BMD. This approach has the potential to make the information offered by HR-pQCT more accessible (and therefore) applicable to healthcare professionals in the clinic if the technology becomes more widely available.

Background Multimorbidity has been shown in several studies to relate to impaired physical function in later life. Aims To examine if self-report of multimorbidity predicts impaired physical functioning, as assessed by formal physical function testing, in community-dwelling older adults. Methods Non-communicable diseases (NCDs) were self-reported by 443 older community-dwelling UK adults via questionnaire, asking the question: ‘Have you been told by a doctor that you have any of the following conditions?’ Assessments of walking speed, chair stands and balance allowed us to create a composite score (0–12) on which impaired physical functioning was defined as ≤ 9. Results The mean age of participants was 75.5 ± 2.5 years for men and 75.8 ± 2.6 for women. The proportion of individuals with impaired physical functioning was 71.2% in women and 56.9% in men. Having four or more NCDs was associated with an increased risk of poor physical function in men and women (p p p Discussion and conclusion Self-report of 4 or more NCDs was associated with an increased risk of poor physical function, an outcome which has previously been associated with adverse clinical sequelae. This observation may inform development of a simple screening tool to look for poor physical function in older adults.

IntroductionSeveral studies have reported the importance of vitamin D status to musculoskeletal health in populations of older adults. Here we report relationships between circulating serum 25(OH)D and musculoskeletal health in a community cohort of UK adults in midlife and investigate whether environmental (dietary intake, use of supplements) and/or genetic factors (4 SNPs previously related to vitamin D status) play more significant roles in determining vitamin D status in this population.MethodsParticipants were recruited from the Hertfordshire Cohort Study, an established longitudinal cohort study of community dwelling adults and were seen at baseline and follow up 9–12 years later. Lumbar spine and total femur BMD were measured at baseline using a Hologic QDR 4500 instrument. Osteoarthritis (OA) was defined by radiographs of the knees graded according to Kellgren & Lawrence at both time points. Serum 25(OH)D concentrations were measured using a DiaSorin Liaison chemiluminescent assay. Genotyping of 4 SNPs previously associated with 25(OH)D values were assessed: (rs12785878 (DHCR7), rs10741657 (CYP2R1) and rs6013897 (CYP24A1)) and a fourth SNP (rs4588), described as “a near-perfect proxy (i.e. substitute) for rs2282679 on the GC gene”.Results820 subjects (397 men, 423 women) participated at baseline, and 339 of these 820 subjects (164 men; 175 women) participated in a follow up study of OA progression. The median (IQR) age of participants at baseline was 64.0 (61.8–66.5) and 65.5 (63.3–67.6) for men and women respectively. Median circulating levels of 25(OH)D were 44.6 (35.0–63.0) nmol/L and 41.3 (29.8–53.5) nmol/L in men and women respectively. Circulating 25(OH)D was strongly associated with season of blood testing (p ConclusionCirculating 25(OH)D levels were generally lower than is recommended in community dwelling adults in midlife, with marked seasonal variation observed, but relationships with reported vitamin D supplementation were weaker. Circulating 25(OH)D was directly associated with hip BMD in men but relationships with BMD in women and radiographic OA were not seen in this sample.

Background The COVID-19 pandemic has led to dramatic changes in people’s lives globally. Older adults have been especially vulnerable to adverse effects from the pandemic including higher mortality and more severe disease complications. At the same time, social isolation, malnutrition and physical inactivity are serious concerns among older adults. The pandemic and associated restrictions may serve to exacerbate these issues, presenting increased risks to physical and mental health. The aim of this qualitative study was to explore how community-living older people in the UK experienced the first wave of the COVID-19 pandemic and how it impacted their health and well-being, and associated behaviours. Methods Qualitative data were collected by conducting serial telephone interviews, with an interval of approximately three months. Participants were from the Hertfordshire Cohort Study, all aged over 80 years. Discussions were audio-recorded, information related to the COVID-19 pandemic was transcribed verbatim and transcripts analysed thematically. Interviews were conducted from March to October 2020. Results Twelve participants were included in the study (7 men and 5 women). Data from a total of 35 qualitative interviews were used, comprising two or three timepoints per participant. Preliminary analysis identified five overarching themes: 1) shopping strategies and food accessibility, 2) limitations on activities and going out, 3) disruption to healthcare, 4) social and psychological repercussions, and 5) coping strategies. Initial findings highlight challenges associated with accessing shops, healthcare, and usual activities due to restrictions. Findings emphasize the issue of loneliness and isolation for some of the participants, especially those living alone, as well as fear of the virus, with restrictions leading to a loss of purpose for some, along with related effects on mental health (e.g. worry, anxiety). For some, these issues appeared to link to a reprioritisation of their behaviours (for example, exercise and diet were deprioritised). Coping strategies used by participants included finding ways to keep busy and to do physical activity safely, maintaining social contact online or by telephone, and having an optimistic or positive outlook, a ‘do what you can’ attitude. Conclusion Analysis is ongoing and will further aim to explore how older people’s experiences and behaviours might have changed over the duration of the pandemic. The findings from this study could improve understanding of how community-living older adults could be supported to be more resilient in the face of a variety of changing circumstances that might impact their health and well-being.

Background Covid-19, a coronavirus that originated in China in late 2019, spread globally to be declared a pandemic by the World Health Organisation in March 2020. The aim of this study was to usean existing cohort of community-dwelling older adults, the Hertfordshire Cohort Study (HCS), to understand how wave one of the Covid-19 pandemic impacted UK older adults, a group particularly vulnerable to severe disease. Methods 71 eligible participants, 39 males and 32 females (drawn from the HCS study, mean age 83.6 (2.5) years, all Caucasian, and community dwelling) were contacted by telephone and asked to complete a questionnaire administered by a trained researcher. Data collection occurred over the period of July to October 2020. Results Over a third (37.1%) of respondents lived alone. Of the remainder, 86.4% lived with a spouse while the remaining 13.6% lived with family. Of concern, 19.7% of participants had felt they needed to go out despite not wanting to; 47.1% had heard of the NHS Volunteer Responders programme, although only 3 (4.2%) had made use of this or other support services. Almost a third (31%) of participants reported they had access to a smartphone, while 62% reported having unlimited internet access, usually using a tablet or computer. Over two thirds (69.0%) of participants rated their understanding of Covid-19 itself as good. Perhaps unsurprisingly, a large majority (88.7%) of participants said their life was different compared to before Covid-19; 80.3% had less social contact and more than half (52%) of respondents reported being less physically active than before the pandemic (and only 4% more so). However, levels of sleep, alcohol consumption and diet were reportedly generally unchanged over the timeframe surveyed. Conclusion We have reported the experience of the first wave of the Covid-19 pandemic among participants of an older Caucasian community-dwelling UK cohort, highlighting the need to consider this group when developing public health interventions to support health and wellbeing, including those employing smartphone technology. Further larger studies in groups of wider socioeconomic status and more diverse racial background are indicated.

Background Osteoporosis is characterised by a reduction of bone mineral density (BMD) and predisposition to fracture. Bone microarchitecture, measured by high resolution peripheral quantitative computed tomography (HR-pQCT), has been related to fragility fractures and BMD and has been the subject of large-scale genome-wide analysis. We investigated whether fracture was related to baseline values and longitudinal changes in bone microarchitecture and whether bone microarchitecture was associated with established BMD loci. Methods 115 males and 99 females (aged 72–81 at baseline) from the Hertfordshire Cohort Study (HCS) were analysed. Fracture history was determined in 2011–2012 by self-report and vertebral fracture assessment. Participants underwent HR-pQCT scans of the distal radius and tibia in 2011–2012 and 2017. Previous fracture in relation to baseline values and changes in tibial HR-pQCT parameters was examined using sex-adjusted logistic regression with and without adjustment for age, sociodemographic, lifestyle and clinical characteristics; baseline values and changes in parameters associated with previous fracture were then examined in relation to four established BMD loci after adjustment for sex and age. Results Previous fracture was related to: higher trabecular area (fully-adjusted odds ratio [95% CI] per SD greater baseline value: 2.18 [1.27,3.73], p = 0.005); lower total volumetric BMD (0.53 [0.34,0.84], p = 0.007), cortical area (0.53 [0.30,0.95], p = 0.032), cortical BMD (0.56 [0.36,0.88], p = 0.011) and cortical thickness (0.45 [0.27,0.77], p = 0.004); and greater declines in trabecular BMD (p = 0.001). Associations were robust in sex- and fully-adjusted analysis. Relationships between BMD loci and these HR-pQCT parameters were weak: rs3801387 (WNT16) was related to decline in trabecular BMD (p = 0.011) but no other associations were significant (p > 0.05). Conclusion Baseline values of HR-pQCT parameters and greater decline in trabecular BMD were associated with fracture. Change in trabecular BMD was associated with WNT16 which has been demonstrated to influence bone health in murine models and human genome-wide association studies (GWAS).

Background Loneliness is an important public health issue associated with mortality and morbidity. Often researched amongst older people, less is known about risk factors for loneliness among adults aged 50–64 years who are in work. We investigated (a) if exit from the workforce increases the odds of loneliness; (b) whether adverse psychosocial work factors are associated with increased odds of loneliness over 2 years of follow-up; and (c) whether the association is stronger among subjects still working compared with those who have exited the workforce. Methods Data came from the Health and Employment After Fifty (HEAF) study, a large population cohort who provided questionnaire information about work and health at baseline and 2 annual follow-ups. Logistic regression was used to explore the association between psychosocial risk factors and loneliness at follow-up 2, with adjustment for loneliness at baseline, sex, age, self-rated health, living alone, and mental health diagnosis. Results Of the initial 8134 participants, 4521 were working at baseline and provided data for this analysis. Of those, 507 (11.2%) were defined as lonely at 2 years’ follow-up. Exiting the workforce was not significantly associated with loneliness (OR = 1.1, 95%CI: 0.7–1.7). However, negative psychosocial work factors predicted loneliness at follow-up. After mutual adjustment, lack of choice at work (OR: 1.5, 95%CI: 1.1–1.9), often lying awake worrying about work (OR: 1.4, 95%CI: 1.0–1.9) and perceived not coping with physical demands of the job (OR: 1.3, 95%CI: 1.0–1.7) were independent predictors, with associations robust to adjustment for demographic factors and health. Associations were only slightly altered when we restricted the sample to those who remained in work until the end of follow-up. Conclusions Loneliness amongst middle-aged working adults is not predicted by permanent work exit but is predicted by individuals’ perceptions about their work. Provision of good-quality work, matched to the capacity of the older worker, could prevent loneliness.

Purpose Social isolation has been associated with both physical and psychological adverse outcomes and is prevalent in older adults. We investigated the impact of social isolation on bone mineral density (BMD) and physical capability in community-dwelling older adults. Methods Data were collected in 2011 and 2017 from the Hertfordshire Cohort Study. In 2011, we assessed social isolation using the six-item Lubben Social Network Scale (LSNS-6) and the Maastricht Social Participation Profile (MSSP) and depressive and anxiety symptoms using the Hospital Anxiety and Depression Scale (HADS). Physical capability was assessed by performing tests of gait speed, chair stands, timed up and go and balance at both time points. BMD was assessed using dual X-ray absorptiometry (DXA) at both time points. Results Data were available from 369 participants in 2011 and 184 in 2017. Forty percent of men and 42.4% of women were socially isolated. Isolated participants had higher odds of depressive disorder (OR 3.01, 95% CI 1.27–7.11, p p Conclusions Social isolation was associated with higher odds of having depressive symptoms and predicted the development of poor physical capability 6 years later. Further longitudinal studies that include loneliness as a covariate are warranted.

Modern understanding of the production and dissemination of thirteenth-century polyphony is constrained by the paucity of manuscript sources that have been preserved in their entirety; the panorama of sources of medieval polyphony is essentially fragmentary. Some of the surviving fragments, however, were torn from lost books of polyphony that were to some extent comparable to well-known extant codices. The fragment of polyphony preserved in the binding of manuscript 6528 of the Biblioteca Nacional de Madrid is illustrative in this respect. This fragment displays a number of codicological and musical features that are strikingly similar to those of the Florence manuscript (F). Both sources share format and mise-en-page, make use of similar styles of script, notation and pen-work decoration,We wish to thank Mark Everist, Carmen Julia Gutierrez and the anonymous reviewers of Early Music History for their invaluable comments and suggestions. Permission to reproduce the images has been graciously accorded by the Biblioteca Nacional de Espana (BNE) and Ministero dei Beni e delle Attivita Culturali e del Turismo (MiBACT). The following library sigla are used: CH-SGs Sankt Gallen, Stiftsbibliothek D-GI Giessen, Universitatsbibliothek E-Mn Madrid, Biblioteca Nacional de Espana F-Pn Paris, Bibliotheque nationale de France GB-Lbl London, British Library In addition, the Ars antiqua manuscripts mentioned in this article are indicated by their familiar sigla: F Florence, Biblioteca Medicea Laurenziana, Pluteus 29.1 LoA London, British Library, Egerton 2615Ma Madrid, Biblioteca Nacional de Espana, 20486 W1 Wolfenbuttel, Herzog August Bibliothek, Cod.

The Madrid fragment thus provides new evidence for a standardised production of polyphonic books in thirteenth-century Paris. The study provides a detailed account of the fragment's codicological and philological features, and explores the hypothesis that it originated in the same Parisian workshop that produced F.

Sleep duration may be associated with risk of osteoporosis, with suggestions that too little or indeed too much sleep may be detrimental to bone health. In this study, we considered whether perceived sleep quality is also associated with bone health in older adults. We explored this association in a cohort of 443 older community-dwelling UK adults. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI); poor sleep quality was defined as > 5 on this score system. Bone density, shape and microarchitecture were assessed using dual energy X-ray absorptiometry (DXA), peripheral quantitative computed tomography (pQCT) and high-resolution pQCT (HRpQCT). Thirty-seven percent of men and 43% of women had a PSQI score greater than 5, indicative of poor perceived sleep. We found that quality of sleep was associated with altered bone microarchitecture. In men, poor sleep quality was associated with lower radial trabecular (4% slice, p p = 0.02) bone mineral density, as well as decreased tibial cortical density (p p p p p p p p

MUSIC FROM MEDIEVAL BRITAINSongs in British Sources c. 1150-1300. Transcribed and edited by Helen Deeming. (Musica Britannica, 95.) London: Stainer and Bell, 2013.

Cloth.

Most of the pieces edited in Helen Deeming's Songs in British Sources c. 1150-1300, monophonic songs in particular, have been so far ne- glected by musicological inquiry, in con- trast with the greater consideration ac- corded to polyphonic music from the same period and provenance. The ambition of this volume, as clearly stated in the preface, is to make "a significant contribution to our knowledge of musical activity in Britain be- fore 1300" (p. xxi). The task is essentially accomplished, as the edition provides good quality transcriptions and translations of early British songs that in most cases have remained silent in their sources for cen- turies, and have not been accessible before. The volume comprises three main sections: an introduction with concise descriptions of methodologies, repertory and its sources, and editorial criteria (pp. xxv-lv); the transcriptions and translations of the songs (pp. 3-160); and a textual commen- tary with brief discussions on the contents of individual sources, and information on individual pieces (pp. 165-224). In addi- tion, a valuable highpoint of this work is certainly the companion online resource in the Digital Image Archive of Medieval Music (http://www.diamm.ac.uk/resources /sbs/, accessed 27 August 2014) that offers highly defined digital reproductions of the original sources, and in-depth analyses of their musical notations.Admittedly, the edition does not seek to be comprehensive: the term song itself, though rather general, limits the range to music that sets poetry (in English, French, and Latin) with no liturgical destination or context. In addition, Deeming further nar- rows the field to exclude certain categories of compositions, as for instance motets, which are essentially set to liturgical chants and have their own separate tradition. It is worth noting that other omissions include the Later Cambridge Songbook (Cam- bridge, University Library, Ff.1.17) and the thirteenth-century Notre Dame collection Wj (Wolfenbuttel, Herzog-August- Bibliothek, 628 Helmst.): the songs trans- mitted in these sources, as Deeming ex- plains, have already been edited in existing publications (The Later Cambridge Songs: An English Song Collection of the Twelfth Century, ed. John Stevens [Oxford: Oxford Uni- versity Press, 2004]; Notre Dame and Related Conductas: Opera Omnia, ed. Gordon A. Anderson, 9 vols., Collected Works = Gesamtausgaben, 10 [Henryville, PA: Institute of Mediaeval Music, 1979-88]). The result is an edition of 115 songs (127, when considering contrafacta, which are provided with their own separate transcrip- tions) transmitted in forty-two manuscripts, all of which are miscellanies that include music as later and occasional additions or as fragments reutilized in the bindings of unrelated volumes (pp. xxxi-xxxii). Latin texts represent the majority of the reper- tory, which is almost entirely anonymous. The context of these songs, as Deeming proposes, is probably clerical, since the sub- jects of the poems are mostly devotional or moral, but not explicitly liturgical, with very few secular occurrences, predominantly limited to the French songs (pp. xxv, xxxiii, xxxviii). The corpus edited here is largely monophonic and syllabic, with some pieces for two and three voices, plus a six-part song, the famous English canon Sumer is icumen in with its Latin counterpart Perspice Christicola (marked as songs 85a and 85b, respectively; pp. …
