The number of references at the end of scientific research papers form a strongly unimodal frequency distribution. It is shown that the generalized inverse Gaussian-Poisson distribution fits such unimodal data extremely well. [ABSTRACT FROM AUTHOR]

There were 48 sets of author productivity data tested against Lotka's Law of xn·y = c. Overwhelming conformity to the law was found. However, only seven data sets fitted the inverse square law. For future tests, representative coverage and good sampling techniques should be adhered to in data compilation. A method is suggested to compute the values of n and c from the data.

A preliminary investigation was conducted to explore which characteristics of citing and cited works may aid in determining relatedness between documents; Thirteen variables were tested on 31 library/information science articles containing nearly 500 citations. Analysis indicates that source of cited work, source of Citing work, number of times a work is cited in text, and type of citing article show promise of Predicting relatedness between citing and cited works.

Success-breeds-success phenomenon is described by single- and multiple-urn models. It is shown that these models lead to a negative binomial distribution for the total number of successes and a Zipf-Mandelbrot law for the number of sources contributing a specified number of successes.

The lines of research leading up to and forming the subfield of bibliometrics are traced from earliest times to the year 1969, when this term was proposed as a substitute for "statistical bibliography." [ABSTRACT FROM AUTHOR]

The journal citations in A Bibliography on Information Science and Technology [13) provide the data for this Bradford graphical analysis. The mixture of scholarly and nonscholarly work which constitutes the periodical literature of information science is discussed, primarily in terms of the ten journals isolated as the core. The analysis is also directed toward as assessment of the completeness of the bibliography. It is inferred that the bibliography is 72 percent complete in terms of journals and 83 percent complete in terms of articles. Two further uses that have been proposed for the Bradford distribution are ranking subjects in order of breadth and determining policy for collections development. The limited results available in these two areas are considered and problems for future research suggested. [ABSTRACT FROM AUTHOR]

In this note we show that the multiplier k that appears in the law of Bradford is not the average production of articles per author nor the average number μ of articles per journal, contradicting some earlier statements of Goffman and Warren and of Vablonsky. We remark how ever that the Bradford multiplier might be close to μ in a lot of cases, being merely a coincidence of the special functional relation between μ and k which we develop in full detail. We finally show that KPA (p = number of Bradford groups, A = total numbers of articles) is a universal constant for the bibliography. Furthermore, K is the Bradford multiplier of a group free formulation of Bradford's law, introduced in an earlier article of the author. [ABSTRACT FROM AUTHOR]

A Bradford analysis was performed on the author and journal series of four comprehensive bibliographies and four related literatures. Goffman and Warren's (1969) minimum zone cohort methodology was used. A clustering Index was introduced that relates the minimum zone cohort to the total recurring cases of a literature. The comprehensive bibliographies and related literatures were compared by clustering indices, Brade ford multipliers, bibliograph slopes, and reference-scattering coefficients. Three of the eight author series were found to be weakly Bradfordian. The distinction between weakly Bradfordian and strongly Bradfordian series found by the clustering index was corroborated by bibliograph slopes. Other bibliometric indicators were unable to discriminate between weakly Bradfordian and strongly Bradfordian series, author and journal series, and comprehensive bibliographies and related literatures. The data were analyzed by The Bibliometrics Toolbox. [ABSTRACT FROM AUTHOR]

A study was undertaken to determine the effectiveness of certain truncated-key structures in retrieving sets of bibliographic records that represent works authored by a single individual. The results show that a key of the form 4,3,1 retrieved one personal author name 98% of the time. A key of the same form retrieved one corporate author name 82% of the time. A stop-list is necessary to eliminate certain troublesome words in corporate! names. [ABSTRACT FROM AUTHOR]
