What does subcollection mean?
A subcollection is a distinct collection within a larger collection. The term is especially common in libraries, museums, archives, art collections, and catalogues, where a broad body of holdings may be divided into smaller groups by provenance, subject, period, medium, or institutional history. For example, a museum might display a subcollection of photographs within a gallery devoted to twentieth-century visual art. In mathematics, the word can refer to a family or set selected from a larger one. Unlike a general phrase such as a group or part, subcollection suggests a recognized or formally defined grouping. It is therefore particularly useful when describing how a collection is organized or when distinguishing one coherent subset from the collection as a whole.
A collection of items within a larger collection, especially a separately organized group within a library, museum, archive, or catalogue.

Where does subcollection come from?
The word was formed in English by combining the Latin prefix sub-, meaning under or beneath, with collection. Both elements ultimately relate to the Latin verb colligere, meaning to gather or assemble. The prefix gives the modern word its sense of something within, subordinate to, or nested inside something larger.
