The chemical and physical properties of 19th and 20th century Chinese papers were investigated using a variety of material characterisation methods. A reference collection of 178 Chinese papers, dating from 1799 to 1990 was used, and properties such as pH, degree of polymerisation (DP), lignin content, and tensile strength (zero-span) were determined. Most of the papers were of approximately neutral pH, had a low lignin content and DP similar to pre-19th century European rag paper. It was found that the high inhomogeneity and the typical paper thinness affected tensile testing and as a result, a modified method for zero-span tensile strength test was developed. Using near infrared spectroscopy (NIR), proof-of-concept partial least squares (PLS) applications were developed for determination of tensile strength, pH, DP and for dating of the samples. For the latter, using post-1900 papers, the error of cross validation was 13 years. The presence of lignin was modelled using linear discriminant analysis (LDA), where the model could distinguish between high and low lignin content with 88% accuracy. Using one or multiple sheets for transmission NIR spectroscopy led to PLS results of similar quality, which was attributed to material inhomogeneity. [ABSTRACT FROM AUTHOR]

Paper occupies a special place in histories of knowledge. It is the substrate of communication, the stuff of archives, the bearer of marks that make worlds. For the early-modern period in particular we now have a wealth of studies of ‘paper tools’, of the ways in which archives were assembled and put to use, of the making of lists and transcribing of observations, and so on. In other fields, too, attention has turned to the materiality of information. How far is it possible to draw a stable methodology out of the insights of literary and book historians, bibliographers, anthropologists, and those working in media studies? Do these diverse fields in fact refer to the same thing when they talk of paper, its qualities, affordances and limitations? In attempting to answer these questions, the present essay begins in the rich territory of early-modern natural philosophy – but from there opens out to take in recent works in a range of disciplines. Attending to the specific qualities of paper is only possible, I argue, if it is understood that paper can be both transparent and opaque depending on the social world it inhabits and helps to constitute. Paper flickers into and out of view, and it is precisely this quality that constitutes its sociomateriality. [ABSTRACT FROM AUTHOR]

This article models a mode of feminist bibliography by "surface reading" paper. Taking Ben Jonson's Sejanus His Fall (1605) as a case study, this article reads watermarks as reminders of paper's three-dimensional materiality, whose surfaces and depths model the more and less legible forms of labor which contribute to paper's making. Watermarks here become a creative and critical prompt to recover the interventions of John Spilman (the papermaker whose output was used for Sejanus), Spilman's workers, and especially his female ragpickers. This article fuses close reading of literary texts and archival sources with bibliography and theory to demonstrate fresh affordances of watermarks—both as they alter our reading of Sejanus and as they intervene more broadly in the affective and political models with which we read.

The history of the Hilfsschule (special school) is contested and multifaceted. For the German context, most research to date has focused on institutions or professional pioneers in special education. This paper, through a "New Historicism" perspective, asks how a group of pupils, described as "retarded", could become a new pedagogical object within a discourse among teachers, psychiatrists, school doctors and local administrations at the end of the nineteenth century. Linking national and local discourses, this paper analyses the emergence of the special school pupil (Hilfsschulkind) in Germany within a broader discourse of educability as well as through knowledge practices, namely record-keeping systems.

This paper describes the Berlin "Abitur" examination in the twentieth century and its written documentation in files. By the late nineteenth century, the "Abitur" examination was fully established in Prussia and with it a graduation certificate that was obligatory for university entrance. Thus, the "Abitur" examination was part of the modern state entitlement system and an instrument to establish the state education monopoly. Thereafter, in every secondary school a new file was compiled for each class that took the exam every year. The resulting records provide a unique insight into the history of examination procedures. This article seeks to discuss the question of the Abitur files being simply products of bureaucratisation and rationalisation of examination practices at secondary schools, and the extent to which there was a ritualisation of the examination on paper. The building processes of the "Abitur" examination files in the twentieth century are reconstructed on the basis of a representative school archive located in Berlin.

Purpose: This paper explores the context within which experimental, pedagogically progressive schools were established in Australia during the first decades of the 20th century. Design/methodology/approach: The paper presents a case study of the establishment of Rosbercon Girls' Grammar School. It draws on educator accounts, archival documents and contemporary literature to provide a brief narrative of the events leading to the opening of the school; to sketch the family of educators who were pivotal in making it a reality; and to identify key aspects of the social and legislative context that made such an initiative possible. Findings: Rosbercon was established at a time when a modest school could be established relatively easily by a small group of educators with a shared vision. The early 20th century was a moment of national optimism in Australia, where an appetite for new educational ideas created a climate in which innovative educators found fertile soil for their pedagogical experiments and adaptation of emerging ideas from around the world. Their efforts were facilitated by an emerging global network of personal interactions, professional learning, professional associations and educational literature. Originality/value: This paper addresses the relative lack of scholarly examination of the origins of Rosbercon Girls' Grammar School, an institution that previous authors have identified as Australia's oldest experimental school. The case study also contributes to a broader appreciation of the trajectory of progressive education during the early 20th century.
