I got a copy of "Proverbs of the Sene-Gambia", by Bamba and Mariama Khan, this morning. It's a beautiful little orange book, very well laid out, with a nice illustration of a xalam player on the cover. Inside is a brief introduction by the authors, then the proverbs start, numbered from 1 through 275, with about five on every page. The small size of the book is a great thing, making it easy to carry around and the whimsical font-face adds to the laid-back tone, letting you flip through at random, on a lazy Sunday afternoon.
The main problem I had with the book was the lack of attribution. In the preface the authors allude to certain resource persons they used for the different languages, which gives you the impression that they did their research well, and built up a database of proverbs before they started.
