Studies with the foraminiferida have often been hindered by widely scattered, inaccessible sources. This two-volume reference (text in one volume, plates in the other) examines 3,568 of the world's generic taxa, representing all geologic ages. Covering twice the number of genera as any other available reference, it is by far the most complete source on the foraminiferida.
