45-49Compares author collaboration in the periodical
literature of African Trypanosomiasis. The study
was based on the literature abstracted in the 1990-
2000 articles of Tropical Diseases Bulletin and
Tsetse and Trypanosomiasis Quarterly (TTQ)
using the counting method. It is found that both
the annual rates and the cumulation of author
collaboration for the period for each of the ten
years was high although the figures obtained for
1992- 1995 and 1998 -2000 were higher than those
for 1990- 1991 and 1996 - 1997. Concludes that
though author collaboration exists in African
Trypanosomiasis literature for the ten years
studied, it is generally high but each year's
literature is dominated by multiple authorship, and
in all, two and three authored papers were
predominant. The extent of collaboration was up
to 11 authors per article, and this calls for more
collaboration to extend the authorship beyond 11
authors per paper, as it is noted in other scientific
disciplines. The study has provided factual
information in support of information services in
the field of African Trypanosomiasis literature
