Reference management

Reference management software, citation management software, or bibliographic management software is software that stores a database of bibliographic records and produces bibliographic citations (references) for those records, needed in scholarly research. Once a record has been stored, it can be used time and again in generating bibliographies, such as lists of references in scholarly books and articles.
Modern reference management applications can usually be integrated with word processors so that a reference list in one of the many different bibliographic formats required by publishers and scholarly journals is produced automatically as an article is written, reducing the risk that a cited source is not included in the reference list. They will also have a facility for importing bibliographic records from bibliographic databases.
Reference management software does not do the same job as a bibliographic database that tries to store records of all publications published within a given scope such as a particular academic discipline or group of disciplines. Such bibliographic databases are large and have to be housed on major server installations. Reference management software collects a much smaller database, of the publications that have been used or are likely to be used by a particular researcher or group of researchers, and such a database can easily be stored on an individual's personal computer.
Many reference management applications enable users to search bibliographic records in online bibliographic databases and library catalogs. An early communications protocol used to access library catalogs, and still in service at many libraries, is Z39.50, which predated the invention of the World Wide Web. Although Z39.50 is still in use, today most bibliographic databases are available as web sites that allow exporting selected bibliographic records in various bibliographic data formats that are imported by reference management software.
