The Trans-Atlantic Slave Trade : a database on CD-ROM contains the records of 27,233 trans-Atlantic slave ship voyages made between 1595 and 1866. These records account for perhaps 70 percent of the Atlantic slave trade, particularly the voyages between 1660, when good data became available, and 1867, when the last recorded slave crossing occurred. Compiled at the W.E.B. Du Bois Institute at Harvard University.The CD-ROM format of The Trans-Atlantic Slave Trade allows users to track information by time period and geographic region and to conduct keyword searches. It also permits the downloading of data in ASCII and SPSS format for use in other programs. Through a series of interactive maps, users can chart the trans-Atlantic connections that underlie these detailed records and thus witness the rise and fall, the direction, and the vagaries of the traffic in humankind. The accompanying data set contains material for 226 fields of information for each voyage, covering the people on board and their experiences, the owners and captains, the ships' characteristics, and the geographic trajectory of each voyage.
