Thanks for all the help, I was able to get nook for PC on my old vista desktop and downloaded my nook library to a thumb drive. I'm going to put calibre on my mac and hopefully put them all in a library there. Right now the only reading device I have is a nook glow plus, any suggestions on a device that supports multiple formats? I will go browse the forum for info on that as well...sheesh so much to learn about all this technology, Id be much happier if it would just poof itself into my ereader without having to jump thru hoops....

I just want to be able to have an efficient library system and one or 2 devices I can read everything with.
