- classification (p. 145): The process of dividing objects or concepts into logically hierarchical classes, subclasses, and sub-subclasses based on the characteristics they have in common and those that distinguish them. (†2011)
- classification (p. 146 (s.v. "classified")): The status of a document to which access s restricted to a few authorized individuals within a military or government agency, research institution, private corporation, or other organization, usually because it contains highly sensitive information that might be misused by unauthorized persons. – Also refers to a reference tool (catalog, index, dictionary, encyclopedia, etc.) organized according to a classification system, usually by subject or some other arrangement based on content, as opposed to a strictly alphabetical or numerical listing of entries. (†2012)
- collaboration (s.v. "collaborator"): A person who works closely with one or more associates in producing a work to which all who participate make the same kind of contribution (shared responsibility) or different contributions (mixed responsibility), for example, essays written by different authors for publication in a collection or illustrations for a children's book in which the text is written by a person other than the illustrator. (†1931)
- declassification (p. 204): A document no longer protected against unauthorized disclosure because the security classification assigned to maintain confidentiality has been officially changed or cancelled. The opposite of classified. (†2010)
- retention : Holding or keeping materials in possession, usually in a desired state or condition, as opposed to disposing of them. In archives, the retention period for documents is usually indicated in the disposition schedule. Academic and research libraries generally purchase materials with the intention of retaining them indefinitely; public libraries weed on the basis of usage and condition. Long-term retention of library materials may require preservation measures, such as reformatting. (†2653)
- retention period : In archives, the length of time that records of a specific category or origin must be retained before they are transferred to intermediate storage or given some other disposition. In the absence of statutory or regulatory stipulations, the period is usually determined by current usage and projected need. (†2654)
- retrieval (s.v. "information retrieval"): The process, methods, and procedures used to selectively recall recorded information from a file of data. In libraries and archives, searches are typically for a known item or for information on a specific subject, and the file is usually a human-readable catalog or index, or a computer-based information storage and retrieval system, such as an online catalog or bibliographic database. In designing such systems, balance must be attained between speed, accuracy, cost, convenience, and effectiveness. (†2652)
