This file contains over 1800 notecards giving citations on colonial African economic history as collected up to 1972. The initial cards list the journals from which citations were transcribed, along with the time frame of documentation. The entries are color-coded by discipline, and the initial card identifies the color-coding. The cards themselves are created by Prof. Patrick Manning (University of Pittsburgh) and 5 history graduate students. The cards are not in any specific order, so one needs to scan through them on a pot-luck basis. That said, all cards in this large file can be freely copied and exchanged.
