Searching for resources other than material in the catalog, such as electronic resources, was (or is) done with separate tools. Using card or computerized catalogs well required skills and jargon particular to libraries. [4] As computerization advanced, OPACs were integrated with other library systems, like acquisition and circulation systems.
Newer generations of library catalog systems, typically called discovery systems (or a discovery layer), are distinguished from earlier OPACs by their use of more sophisticated search technologies, including relevancy ranking and faceted search, as well as features aimed at greater user interaction and participation with the system, including tagging and reviews.

The standard format used to refer to Abell clusters is: Abell X, where X = 1 to 4076.E.g. Abell 1656. Alternative formats include: ABCG 1656; AC 1656; ACO 1656; A 1656, and A1656. Abell himself preferred the latter, but in recent years ACO 1656 has become the preferred format among professional astronomers and is the one recommended by the Centre de Données astronomiques de Strasbourg
