Having so many books, wouldn't it be nice to have a software application to manage all of them?
From the description: eLibrary is such a software utility to manage your personal book collection (both print books and ebooks). Book information can be downloaded from the Internet; what you need to do is just enter one or more ISBNs, or simply use your barcode scanner.
eLibrary is
free and a really valuable tool for every serious e-book reader (I am using it, too). Only caveat: it requires Windows.
