WorldCat Confidence: 84% Arrow up

WorldCat is a union catalog that itemizes the collections of 72,000 libraries in 170 countries and territories that participate in the Online Computer Library Center (OCLC) global cooperative.

It is operated by OCLC Online Computer Library Center, Inc. The subscribing member libraries collectively maintain WorldCat's database.

Active Directory Confidence: 82% Arrow up

Active Directory (AD) is a directory service that Microsoft developed for Windows domain networks.

It is included in most Windows Server operating systems as a set of processes and services.

Initially, Active Directory was only in charge of centralized domain management.

Starting with Windows Server 2008, however, Active Directory became an umbrella title for a broad range of directory-based identity-related services.

Library catalog Confidence: 75% Arrow up

A library catalog or library catalogue is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations.

A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library.
