RefWorks, how do I love thee, let me count the ways...
Ok, so this will be an uncritical gush... RefWorks released an update last night that adds some very cool features. They are really listening and competing with the Connoteas of the world.
1) Create RSS feeds from shared folders (probably requires RefShare)
2) Create author, descriptor, or keyword URLS
3) New "link to this page" feature
4) Browser bookmarklet to capture web page information
Also, in August they added a bunch of new features like auto-complete that make it easier to find information and standardize author and journal names and the ability to read RSS feeds from databases and quickly import new records.
Update: Randy points out that these features are only available if your institution subscribes to RefShare -- at an additional cost. Sorry!
Update on my update: I forgot to give Randy
link love... sorry Randy
! Keep blogging
! (oh, yeah, and I corrected the typo in the update)
