Chrome: If you've ever written an essay, you know the pain of formatting citations. refDot is a Chrome extension that pulls those citations from Amazon for you automatically.
With Amazon's massive book database in tow, refDot pulls out the citation information for the books your viewing and displays it in a TXT or HTML format. You can add as many as you need to all at once. The feature set doesn't include automatic newspaper article citations, but if you're referencing a lot of books it's a handy means to quickly get the information you need without having to sift through the copyright information inside the physical tome.
