Yes. I have a T1, use it all the time with Calibre, and when I want to download a library book, grit my teeth and use ADE. There's a similar thread related to library borrowing, which reminded me of the fact that it was a bit of a faff to set up, so if you do want to use the T1 with ADE for library books, the story of my faffing might help!
