Because I have a working copy of the librarian software, I've not used the personal document server in a long time. I may have broken my access to the server when I registered my 2150 which can reach the server but since I don't remember how to get books there anyhow, I have not tried it in quite a while.
If you don't want to use a card reader, impbuild will create books for your reader and impserve will get books on your reader. Look for a sticky topic at the top of the eBookwise page or go here,
