A collection is a group of resources that have been selected for some purpose.

  • Resource-type: a novel, biography, etc. (ordering on the type of artefact)
  • Resource-kind: coin collection, stamp collection, etc. (ordering on the medium of artefact)

A collection itself can also be a resource. An index is a description resource that contains information about the location and frequencies of terms in a collection to enable more efficient search.

What then is a library? According to Glushko, they are organizing systems which “select, collect, organize, conserve, preserve, and provide access to information on behalf of a community of users.”
