I must have between 2-4k books in my possession and it has got to the stage where I am buying novels from Amazon because I don't know whether I have them already or can't find them. I've been very impressed with RedLaser and its speed at a barcode reader. I've also noticed that it has the ability to export a list of raw barcode numbers as an email attachment. Line separated values. Does a Mac application exist that could import that .txt list and load up a 'library' of my books, searching the raw barcode number with some online source to give the title, author and maybe jacket cover image? It would be cool if I could then enter more information as to where the book was in the house 'upstairs bathroom bookcase' or such.. At present my books are organised aesthetically, that is they are clumped together in contrasting or complementing colours with the walls depending on the room. Such a mythical app probably doesn't exist but I'd appreciate it if anyone who knew of one (or who could propose a viable alternative aside from rearranging) would let me know. Thanks.
