Simple Document Imaging for Unix?

andylievertz asks: "I have developed a logical system of directories for storing my digital documents (i.e. *.doc, *.mp3, *.gif, etc.), and can usually find any obscure document with relative speed. These 'must-keep' hardcopies include everything from bills and shipping invoices to brochures and chinese-food menus. I've tried applying my electronic filing techniques to an actual, real-world filing cabinet, complete with folders and labels, but such a system: requires a great deal of effort to maintain relative to the electronic system, especially considering the frequent influx of new hardcopy material; and doesn't address the greater issue of reducing the sheer paper bulk, organized or not. What solutions have you, the Slashdot Reader, employed to solve this situation for yourself? Are there viable Unix-based Document Imaging packages, similar in function to the Microsoft Document Imaging utility packaged with Office? Do you use a Unix-based Document Imaging solution personally or professionally? If so, what package, and why does it work for you?"

"So, step one is to find ways to reduce the influx of hardcopy (i.e. electronic billing, etc.), but for me, the second step is to find and utilize a [Unix-based!] system that will allow me to scan and file hardcopies electronically so they may be indexed, searched, re-organized, shared, and retrieved as easily as their electronic counterparts. Naturally, any such system would need tolerances for multi-paged documents, and would need to store its output in a non-proprietary file format."

I have a trash can in my office that my girlfriend loves to throw all my important documents in.

Which important documents? The ones from Playboy?
