I've been a moderately happy citeulike user for quite some time, but their community-developed scrapers have been growing less consistently useful over time - more and more, I have been forced to add citations to my repository by hand. I'm going to try something new, perhaps you've heard of it?ZoteroZotero is a Firefox extension that is (also) able to scrape citations from many types of web pages. It also incorporates a nice feature set for tasks like organizing, note taking, and exporting. The site claims it will support sharing citations in the future, though I admit that I've never used citeulike's community features in a serious way. Finally, I was able to move my citations from citeulike to Zotero in about a minute (!).Have fun citing things!Max
