Theres a handy little program called "Booksorter.rar" that scans books, normalizes names, and sorts (and then copies them into) output "buckets" file (primary output is by author, secondary is you can set the genre by author name to slip it into the correct Genre basket)
ps, if you can't find it online, i have it in my library, but don't know how to attach it to the messaging thing here, feel free to send me email
