A sheet catalog is a library catalog that consists of individual catalog sheets that are collected in loose-leaf binders, clip-on folders, ring binders or plastic sleeves.
It is kept in list form. Either several catalog entries are continuously typed on sheets (A4 or A5) or each catalog entry is given its own sheet ( loose-leaf collection ). One advantage over the tape catalog is that sheet catalogs are more manageable and mobile. Adding supplements is easier, as is changing damaged sheets. The typewritten guidance also allows the production of several copies. Managing the catalog is, however, time-consuming, as the folder has to be closed for each supplement.
