Publications and citations by country (time series)

[Philip Davis]

I'm looking for a dataset that includes country-level data for number of 
publications and citations (i.e. reference length) for at least 10 years.

The purpose of my request is to confirm a trend that I'm detecting in 
publications from authors located in sub-Saharan Africa.  If anyone is 
willing to share (or point me to a source), I'd be very appreciative.

Thank you,
Phil Davis
