Hi all,
I have spent much time searching the internet for a good method to transition my father's library and thought the folks on this forum could help. Here's my situation:

My father has a library list containing 3k+ books on Microsoft Word of all physical books, including ebooks purchased from Amazon and B&N. He also has the date he finished the book along with a rating. Unfortunately none of his entries contain ISBN #'s (only author first and last name). I would like to put his library in a medium that allows portability (GoodReads or Shelfari) but I also find Calibre a very powerful library program.

Does anyone know of or recommend an efficient way to obtain the ISBN numbers and any recommendations on what medium would be easiest to establish his new library?

Thanks for your time and suggestions.
