The Jet Propulsion Laboratory (JPL) Library defines a project bibliography as a bibliography of publicly available publications relating to a specific JPL instrument or mission. These bibliographies may be used to share information between distant project team members, as part of the required Education and Public Outreach effort, or as part of required reports to management or sponsors. While some bibliographies may be done by the mission's team members, the JPL Library staff has been involved in a number of project bibliographies over the years. The JPL Library currently has 10 ongoing project bibliographies. Basic requirements and search terms are developed by discussions with the project representative. For most of our project bibliographies this means looking for the project/mission name in the title, abstract, or keyword fields in commercial databases. We provide regular updates to the project. Metrics compiled from the comprehensive bibliographies have been particularly useful to projects. Both metrics and the publication lists support the contribution by JPL missions to scientific knowledge.
