The various volumes of the Yale Zone Catalogues have been combined into a single, homogeneous, machine-readable volume, sorted by position, containing the information common to most of the volumes. Additional data are provided in separate files. The notes have been transcribed into a machine-readable form. Errors detected in the course of the preparation of the catalogue, as well as previously known errors, have been corrected, and supplementary data have been added.
