Nook ST Glow + Calibre = very good thing stock =)
I have used Calibre for years now, and just got a new NSTGlow for xmas.
Calibre works fine with the ST.
Its a life saver.
A sugestion if I may, if you have favorites that you go back to over and over etc. (for me Im working thru several versions of the Bible right now)
Instead of making a shelf, make a directory of the books etc you want, then move that directory to one of the alternate material "types" directory on your nook.
IE ... I made a directory of all my bible related books, named it "bible" and copied to the "document" folder on my nook.
That way when I want to reference those books quickly, instead of opening up my "books" folder, I open up the "document" directory and get what I want directly.
I really do wish they would make organizing shelfs better / easier.
You should be able to add a book to a shelf while browsing your directories and remove one form a shelf buy looking at the shelf.
You shouldnt have to sort thru your entire collection of books to add / remove something ( ggeess i have over 2k books .. thats insane to try and do )
