From the American Library Association:

Late on Friday, March 14, President Trump issued an executive order attempting to dismantle the only federal agency dedicated to funding library services, the Institute of Museum and Library Services (IMLS). Millions of people rely every day on library services and programs supported by IMLS. Now we need YOU to show up for our libraries.

If you are so inclined, the ALA has provided a convenient online form to contact your representatives about the proposed cuts to IMLS.

For additional information, you can read the ALA statement on White House assault on the Institute of Museum and Library Services.
