Check out the Digital Government Document's Clearinghouse, a project of the American Library Association's Government Documents Round Table.

The goal of the project is to collect information to facilitate cooperation and partnerships between libraries for digitization projects. They hope to do so by providing a centralized database of digital resources for local, state, federal, and international government documents that are currently planned, in progress, or already completed.

You can add a project (not necessarily your project) to the database, or search it by keyword (though I'm certain they'll have more sophisticated retreival of the information once the project is completed). From what I can tell, there are already in excess of 150 digitization initiatives already entered into the database.
