BibDesk is an open-source reference management software package for macOS, used to manage bibliographies and references when writing essays and articles. It can also be used to organize and maintain a library of documents in PDF format and other formats. It is primarily a BibTeX front-end for use with LaTeX, but also offers external bibliographic database connectivity for importing, a variety of means for exporting, and capability for linking to local documents and automatically filing local documents. It takes advantage of many macOS features such as AppleScript and Spotlight.
