Rinisari (521266) writes "Since striking out on my own nearly a decade ago, I've been collecting bills and important documents in a briefcase and small filing box. Since buying a house more than a year ago, the amount of paper that I receive and need to keep has increased to deluge amounts and is overflowing what space I want to dedicate. I would like to scan everything, and only retain the papers for things that don't require the original copies. I'd archive the scans in my heavily backed up NAS. What free and/or open source software is out there that can handle this task of document management? Being able to scan to PDF and associate a date and series of labels to a document would be great, as well as some other metadata such as bill amount. My target OS is OSX, but Linux and Windows would be OK."
