2011 Museum Computer Network (MCN) conference in Atlanta, GA Presentation given on November 19. PRESENTERS: Carolyn Sheffield, Project Manager, Field Book Project, Smithsonian Institution Danielle Castronovo, Archives & Digital Collections Librarian, California Academy of Sciences Rebecca Morin, User Services Librarian, California Academy of Sciences The Field Book Project, The Biodiversity Heritage Library (BHL), and Connecting Content are distinct yet intersecting projects that use collaboration and innovation to leverage resources and improve access to important natural history collections. Each can be defined as collaborative in its own right. The three projects also directly collaborate with one another to build connections and ensure compatibility across related resources. The Field Book Project is a CLIR-funded project to improve access to primary-source field books at the Smithsonian and is being extended to accept content from other natural history museums. BHL is a consortium of 12 libraries working to digitize and deliver legacy taxonomic literature, and Connecting Content is an IMLS-funded project to define and provide logical connections between field notes, specimens, and published literature.
