Unseen Library - Guards! Guards!

I am looking to purchase or trade for a copy of Guards! Guards! the Unseen Library edition. Please let me know if anyone has a copy they don't mind getting rid of...

Also, I saw a webpage once that listed out the Unseen Library books they printed, they didn't do the whole series...but for the life of me, I can't find that page now, any help here???
