Digitizing Hidden Special Collections and Archives, a program of the Council on Library and Information Resources (CLIR), is intended to help digitize and provide access to collections of rare or unique content in cultural heritage institutions. The program supports projects that make digitized sources easily discoverable and accessible alongside related materials, including materials held by other collecting institutions as well as those held within the home institution. Collections proposed for digitization may be in any format or relevant to any subject. Grants, ranging from a minimum of $50,000 to a maximum of $250,000 in the case of a single-institution project or $500,000 for a collaborative project, will be provided to colleges and universities, research centers, museums, libraries, historical societies, cultural associations, and select government units. Online initial proposals must be submitted by April 3, 2019; final proposals are due September 17, 2019. Visit the CLIR website to review the program guidelines and application process.
