Databases incorporating data from IAPT publications (examples):

Botanical Collectors Database at Harvard [now included in Index of Botanists] "The names and information on collectors and collecting teams was obtained from numerous sources, but the largest number of records is derived from the International Association for Plant Taxonomy's (IAPT) Index Herbariorum series, Index Herbariorum, Part II, Collectors A-Z and from the list of staff members in the 8th edition of Index Herbariorum, Part I, The Herbaria of the World. The records make use of the 7-bit ASCII character set. Names that use diacritical marks have been flattened to their nearest ascii equivalant."

Publications Database at Harvard [now Index of Botanical Publications]
Includes the titles and abbreviations of publications from Taxonomic Literature, second edition (TL2) (Stafleu and Cowan, 1976, 1979, 1981, 1983, 1986, 1985, 1988), and Taxonomic Literature, edition 2, Supplement (TL2/S) (Stafleu and Mennega, 1992, 1993, 1995).
