I have a relatively large collection of useful books (paper and electronic), [academic] papers (mostly electronic) and web bookmarks. However, I don't have an overview of the material. Currently I have most of the electronic (PDF/DJVU) material in a single hierarchical folder and use filename search.
Do you have a similar problem, and how do you deal with it?
Can you recommend some software to help with organizing bibliographic information, including web links. Easy editing of hierarchy and tags is a must. I would also like to be able to write own comments for each entry. [With my current scheme, just using the filesystem, does not provide other metadata.] A plugin for emacs would be perfect, but it's not a must. (org-mode MIGHT be adequate).
