==History==
Library classifications were preceded by classifications used by bibliographers such as [[Conrad Gessner]]. The earliest library classification schemes organized books in broad subject categories. The earliest known library classification scheme is the [[Pinakes]] by [[Callimachus]], a scholar at the [[Library of Alexandria]] during the third century BC. During the Renaissance and Reformation era, "Libraries were organized according to the whims or knowledge of individuals in charge."<ref>{{Cite book|title=The library : an illustrated history|last=Murray|first=Stuart|date=2009|publisher=Skyhorse Pub.|isbn=9781602397064|___location=New York, NY|oclc=277203534|url-access=registration|url=https://archive.org/details/libraryillustrat0000murr}}</ref> This changed the format in which various materials were classified. Some collections were classified by language and others by how they were printed.
