What should I use to make a web dictionary of my brain?

I take a lot of screenshots on the web (quotes, statistics, paragraphs from articles). I also have links to webpages and articles I want to come back to.

I have all my screenshots in a folder, and all my bookmarks on Delicious. Do you know of any apps that can combine these two into a Mind-Dictionary? I do a search for headaches, and boom it tells me a few articles I’ve bookmarked, some of my screenshots, etc. It doesn’t even need to be an app, maybe you do something cool with screenshots and links on yr computer that accomplishes the same thing. I have a Mac.
