Short-title catalogue
A short-title catalogue (or catalog) is a bibliographical resource that lists printed items in an abbreviated fashion, recording the most important words of their titles. The term is commonly encountered in the context of early modern books, which frequently have lengthy, descriptive titles on their title pages. Many short-title catalogues are union catalogues, listing items in the custody of multiple libraries. Online short-title catalogues in fact tend to record complete (and therefore longer) title transcriptions.
