Here's an excerpt from the announcement:
The Institute of Museum and Library Services announced the guidelines for the first round of FY 2018 National Leadership Grants for Libraries (NLG) and Laura Bush 21st Century Librarian Program (LB21). The NLG program invests in projects that address challenges faced by the library and archive fields and generate results such as new tools, research findings, or models that can be widely used. The LB21 program supports human capital capacity projects for libraries and archives. This call for preliminary proposals has a deadline of September 1, 2017, for both programs. A separate funding opportunity for both programs will be announced in December with a deadline in February 2018.
