Abstract: Bibliographic data on HIV/AIDS literature on Nigeria and South 
Africa were drawn from Medline and Science Citation Index (SCI) 
respectively, covering the period 2000-2004, to study the productivity of 
literature produced by 'all authors', first authors, 'non-collaborative 
authors' and 'co-authors' using Lotka Law. The first authors in Medline 
did not yield usable result for Nigeria, but the characteristic exponents 
for the other categories of authors are higher for Nigeria (6 ranging 
between 2 and 4) than South Africa (6 ranging between 2 and 3). Based on 
SCI, the model yielded only useful result for the Nigerian co-authors, 
whereas all other categories of authors yielded exponents that ranged 
between 1 and 3 for South Africa. We deduce that Medline appears to 
accommodate HIV/AIDS literature emanating from Nigeria more than it does 
those coming-from South Africa, while the opposite is the case with SCI 
Finally, scientific productivity in Nigeria is more significant when 
assessed based on Medline than SCI. The reverse is the case for South 
Africa.
