World and DR Congo book publications

I looked again at the book publication data mentioned in my post-before-last, and drew up a table of world publications from 1995 and compared them with DR Congo publications from the same year. The table is below.

The Congolese publications are in subjects involving much less physical capital or formal education in their preparation than the world publications, and consequently leading to less transfer of the knowledge about subjects involving them. I am not sure how much of the division is due to supply (writing interest and expertise) or demand (reader interest) in the DR Congo.
