It seems a Senate Committee recommended that the Environmental Protection Agency reopen their libraries. More information can be found here.
ALA has started a wiki for federal libraries that are under threat, closing or being reorganized. Check it out here.
From the wiki:
The purpose of this wiki is to share and track information on federal library threats, re-organizations, and closings. Based on discussions with members, the main focus is to facilitate reporting of threats or closings that will enable users to make comments about that specific library’s situation.
With that in mind, each library will have its own webpage. Libraries that currently have pages are listed at left. If you don’t see a particular library listed, follow the instructions at the bottom of the screen in order to create a new webpage.
