Playing around on the website of the National Endowment for the Humanities’ Office of Digital Humanities this afternoon I came across the Library of Funded Projects, a database of projects funded through the ODH. Visitors can search by Categories (technical focus of the projects, not subject), Grant Programs, or by keyword. Project records include most information one would want including PI, award dates, funding, abstract, link to project website (when one exists), and a space to link project white papers (which are required at the conclusion of all ODH-funded projects).
The LFP is not up-to-date; searches for several of the grant programs come up empty (including those where there are currently funded projects). Even so, this could be an immensely valuable resource to help scholars keep abreast of new work being done in the field, especially the smaller projects supported through the Start-Up program.
(The keyword search, as most keyword searches, needs some working with. “Classics” turns up nothing, while “classical” and “ancient” pull up two different but slightly overlapping lists.)
UPDATE: Are there similar libraries/databases for other national funding agencies (DFG, JISC, etc.)? If so, please cite them in the comments. Thanks!
