2. Introduction
Tamil is one of the most classical and an ancient South Indian Languages. In ancient times, the assembly or academy of most learned men of Tamil land was called “Sangam” and the literature produced from these assemblies is known as the “Sangam literature”. Sangam age also renowned as “Golden Age”.
The bibliometric study is a budding area of research in Library and Information Science which quantifies and qualifies the scholarly output of any literature. The bibliometric study projects the strong and weak areas of any research or documentation of bibliographical databases.

Productivity of written communications.

5. Objective To apply bibliometric techniques available Tamil literature
Digital South Asia Library’s NBIL,

used by Tamil scholars and researchers
This study exploits the characteristics of
Tamil literature output in NBIL.

6. Significance of the study
NBIL - bibliographic database
freely available
56,000 titles with imprints prior to 1954
22 Indian languages.
To study Tamil literature output in NBIL
Prediction of literature growth,
author pattern,
language dispersion &
descriptor pattern.

7. Methodology Database : NBIL
Search Term : “tamil” (not case sensitive) Hits : 1218
S/w : MS-Word and MS-Excel.

8. 1. Literature Growth Study
One of the important aspects in bibliometric study is the prediction of the pattern of growth of literature.
Figure 1. Actual Growth of Tamil Literature (1886 to 1958)

9. Literature Growth Study…
Top 8 years productivity publications (57.31%)
1886 to publications (42.69%)
Most productive years to 1953
Most productive year (127 publications).
The linear trend calculates to 0.852x

10. 2. Authorship Pattern
Authorship study - kind of authors, nature and degree of collaboration .

11. Authorship Pattern… 13 authors - 10 to 50 publications.
71 hits no statement of responsibility.
Most productive author - Kotaiyammai, Vai, Mu (4.36%)
The productivity difference among others - not quite high
13 authors publications (24.15%)
Others to 7 contribution(s)
13 authors’ output < rest (75.85 % - high)

12. 3. Language dispersion
Language (document) -important factor- bibliometric studies
References cited – depend - language of the documents.
Non familiarity of a language – less citations.
Translated works – cited by many.

13. Pie diagram - rest of 119 hits language distribution.
Language dispersion…
Tamil ranks % (First)
Bilingual works %.
Sanskrit II
Sanskrit and Tamil III
English language IV
Pie diagram - rest of 119 hits language distribution.

14. 4. Document Type
Microforms - films or papers containing micro reproductions
(reduced to about 25 times of size) of documents
storage, retrieval, transmission, and printing.
NBIL microfilms the Indian publications –
Microfilming of Indian Publications Project (MIPP).
Govt. of India - approved a project by the National Library, Calcutta
Preservation Early 20th-Century South Asian Books.
MIPP - preserving and making books accessible in the NBIL list
together with the pre-1954 titles in the NBIL supplement.
In this analysis, out of 1218 documents, 944 documents are microfilmed which accounts to 77.50%. This is an appreciable mode of digital preservation for reference.

15. 5. Subject Dispersion Study
Subject dispersion study - bibliometric study
concentration of subject areas of documents;
funding agencies to disburse the grant
based on the strong subject areas;
enhance research in the needy and weaker areas.
The retrieved 1218 documents are categorized under 615 subject headings.

16. Subject Dispersion Study…

17. Subject Dispersion Study…
The top 15 ranking subject areas are tabulated.
Usually, number of subject areas >number of documents
(Because one document may belong >1 subject area)
Philosophy and Religion % (First)
History, biography and travel % (Second)
Literary Criticism & General Anthology – 3.01% (Third)
The priority of subject areas as per NBIL is highlighted.

18. Conclusion As per the bibliographical database,
The literature growth pattern analysis predicts that
productivity reached its peak during 1946 to 1953.
ups and down during the growth.
The authorship pattern study shows that
Kotaiyammai, Vai, Mu –most productive author
Collaborative authorship pattern cannot be predicted
only single author contribution.
Of course, there exist translators and editors.

19. Conclusion… The language dispersion analysis yields that
“Tamil” is the most predominant language (90.23%)
Others are bilingual
The document type analysis yields that
77.50% microfilmed documents
Subject Dispersion analysis shows that
“Philosophy and religion” subject areas - first preference
“History, biography and travel” - follows

20. Suggestions:
The National Bibliography of Indian Literature database focuses from 1901 to 1954 and holds about 56,000 imprints prior to 1954; policies may be framed to include the scholarly output in Tamil prior to this period, since Tamil is a classical and an ancient language.
Apart from preservation in any format, the bibliographic databases dedicated for scholarly output in Tamil may be created and launched freely over the internet.
The creation of online bibliographic databases of scholarly output in Tamil spreads the richness of the scholars and researchers who publish their output in Tamil.

21. Suggestions…
4) Citations may be made by the scholars and researchers from these databases, which in turn raise the impact factor of Indian journals and Indian authors.
5) The creation of databases results in reducing the unemployment crisis and provides a wealthy literature output for the future generation.
Uniformity in transliteration and subject term specification through subject experts may be preferred to increase precision in databases.
Literacy programmes on the usage of these bibliographical databases may influence the researchers, scholars and authors to publish their findings in the journals indexed in these databases.
