Books for the Families of the Troops?

Taking this blog off hiatus for a quick post...

Are any libraries out there sponsoring programs to give books to the families of the troops? or sending books/magazines/DVDs/CDs to the troops?

I don't know if the USO or the military has a program that already does this, but it seems like it would be a great idea to take some of the great materials that are going to a library book sale and sending them to the troops or troops families...I know the military probably has libraries as well, but I'll bet they're underfunded...
