    • ORIGIN AND DEVELOPMENT• The historical review says that F.J. Cole and Nellie B. Eates presented the first recorded study on “bibliometrics” in 1917 in science progress.• Hulme was the first to use the expression ‘statistical bibliography’ in 1923.• One of the pioneers was PRITCHARD suggested the word ‘bibliometircs’ in 1969.
    • DEFINITION AND MEANINGS• Bibliometrics-divided into two words – Biblio - Latin/Greek Word – ‘Books’ – Metrics - Latin/Greek Words – ‘Measurement’. – Bibliometrics to denote application of mathematical and statistical methods to book. This is called as a quantitative analysis.• According to Hawkins (1977) defined bibliometrics as “ the application of quantitative analysis in the bibliographic references of the body of literature”• The British Standard Institution (1976) described the same bibliometrics as the “application of mathematical and statistical methods in the study of the use of documents and statistical methods in the study of the use of documents and publication patterns.”
    • SCOPE OF BIBLIOMETRICS DESCRIPTIVE EVALUATION STUDIES STUDIES Productive count Literature usage countWhich attempts to study the Which attempts to study body of literature by the use of a body of counting its contributing literature by using citationcountries, authors, journals, analysis. year of publication, and disciplines.
    • BIBLIOMETRICS LAWS• LOTKA’S LAW(1926) author’s Productivity• BRODFORD’S LAW(1934) scattering• ZIPF’S LAW (1949) word frequency
    • BIBLIOMETRICS SOFTWARE• THE BIBLIOMETRICS TOOLBOX- the bibliometrics toolbox was first bibliometrics programmed package. It has developed T.A.Brookes to assist bibliometricians in preparing statistics form their down loaded data.• DATAVIEW BIBLOMETRICS SOFTWARE FOR ANALYSIS OF DOWNLOADED DATA- dataview is commercial software.• BIBEXCEL – this software is designed to assists a user in analyzing bibliographic data, or any data of textural nature formatted in a similar manner.• BIBTECHMON- commercial product
    • APPLICATION OF BIBLIOMETRICS• To study research trends and growth of knowledge.• To estimate comprehensiveness of secondary periodicals.• To identify users of different subjects.• To identify authorship trends in documents on various subjects.• To measure the usefulness of retrospective and current awareness services.
    • APPLICATION OF BIBLIOMETRICS• To identify past, present publishing trends as well as forecast future publishing trends.• To develop experimental models.• To identify core periodicals in different disciplines (through application of Bradfords law of scattering and citation analysis)• To formulate stacking and weeding policies.• To initiate effective multilevel network system.
    • APPLICATION OF BIBLIOMETRICS• To formulate collection development/ management policy.• To study obsolescence and dispersion of scientific literature.• To study productivity of institutions/ individuals and disciplines.• To develop norms for standardization.• To design automated language processing for auto indexing, auto classification and auto abstracting
    • LIMITATION OF BIBLIOMETRICS• More formula oriented .• Bibliometric study does not include the informal publications and communications. Therefore, the scientific development cannot be predicted properly.• The bibliometrical references, which are taken for citation analysis study, are not always standardized.• this causes problem while ranking the authors on the basis of the frequency of their getting citations.
    • LIMITATION OF BIBLIOMETRICS• For example, the author S.R. Ranganathan has been cited variously as Siyali Ramamrita Ranganathan , S. Ranganathan and S. R. Ranganathan. This may cause scattering of citations of same person-works.• At the same time it may also happen that there may be more than one author under the same name and it may be difficult to distinguish them.
    • CONCLUSION CUM ADVANTAGES• Bibliometrics is a type of research method used in library and information science.• It is a quantitative study of various aspects of literature on a topic and is used to identify the pattern of publications authorship and secondary journal coverage with the objective of getting an insight into the dynamics of growth of knowledge in the areas under consideration.• The adoption of bibliometrics techniques in various disciplines stimulate stunning growth of literature on bibliometrics and its related areas.
