But, seriously, there is a great extension out there for researchers, writers, students, any one who needs to keep stuff organized, and referenced. It sure beats 3×5 cards. 😀
It’s called Zotero:
Zotero [zoh-TAIR-oh] is a free, easy-to-use Firefox extension to help you collect, manage, and cite your research sources. It lives right where you do your work — in the web browser itself.
You can save whole webpages, pdfs, images, citation sources from webpages, etc. It works with Amazon, Google Books, Library of Congress, many university libraries, (here’s a list of compatible sites) and if used with the book burro extension helps find books cheap. You can even save notes in EndNote format with it.
(Hat tip to BoingBoing for this)
