A Term Catalogue (German: Messkatalog) is a serial publication compiled to inform customers—most importantly book traders from other cities—of the book production as available on the book fairs. The first such catalogue was issued by Georg Willer in Augsburg in 1564. Several projects followed the model including the series of English Term Catalogues issued by John Starkey and Robert Clavell under the title Mercurius Librarius, or, a catalogue of books from 1668 to 1711.[1] "Term" referred to the dates of the fairs that would be held as platforms of the trade.
The catalogues are a valuable source to researchers today, because they often give dates of the publication processes and information about working titles that were eventually dropped. The segmentation is of interest for its contemporary perspective on the market: a perspective modern literary histories no longer share.
