TL;DR: This electronic version was converted to PDF from the original manuscript with no changes apart from typographical adjustments and it has been ensured that the page numbering of the electronic version matches that of the printed version.
Abstract: Information Retrieval Interaction was first published in 1992 by Taylor Graham Publishing. This electronic version, published in 2002, was converted to PDF from the original manuscript with no changes apart from typographical adjustments. It has been ensured that the page numbering of the electronic version matches that of the printed version. Both versions can therefore be cited as:

TL;DR: The origins and historical survey of the development of each of these terms are presented, and the size of the overall literature of these fields is determined and the growth and stabilisation of both the dissertation and non-dissertation literature are shown.
Abstract: Since Vassily V. Nalimov coined the term ‘scientometrics’ in the 1960s, this term has grown in popularity and is used to describe the study of science: growth, structure, interrelationships and productivity. Scientometrics is related to and has overlapping interests with bibliometrics and informetrics. The terms bibliometrics, scientometrics, and informetrics refer to component fields related to the study of the dynamics of disciplines as reflected in the production of their literature. Areas of study range from charting changes in the output of a scholarly field through time and across countries, to the library collection problem of maintaining control of the output, and to the low publication productivity of most researchers. These terms are used to describe similar and overlapping methodologies. The origins and historical survey of the development of each of these terms are presented. Profiles of the usage of each of these terms over time are presented, using an appropriate subject category of databases on the DIALOG information service. Various definitions of each of the terms are provided from an examination of the literature. The size of the overall literature of these fields is determined and the growth and stabilisation of both the dissertation and non-dissertation literature are shown. A listing of the top journals in the three fields are given, as well as a list of the major reviews and bibliographies that have been published over the years.

TL;DR: The scope and significance of the field of informetrics is defined and related to the earlier fields of bibliometrics and scientometrics; the phenomena studied by informetricians are identified.
Abstract: The scope and significance of the field of informetrics is defined and related to the earlier fields of bibliometrics and scientometrics. The phenomena studied by informetricians are identified. The major contributors to the field in the past are described and current emphases are related to the contributions in this Special Issue.

TL;DR: The model is derived from S. C. Bradford's ‘law of scattering’ and is called the Bradford Distribution and is used to predict the reference yield of abstracting journals in a search for thermophysical property data.
Abstract: The distribution of references in a collection of pertinent source documents can be described and predicted by the relation where the parameter s is related to the subject field and the completeness of the collection The model is used to predict the reference yield of abstracting journals in a search for thermophysical property data It is used also to explain differences among various literature studies of the past in terms of differences in subject and comprehensiveness of search The model is derived from S C Bradford's ‘law of scattering’ and is called the Bradford Distribution
