I've just opened a new account in RefWorks, I it very easy, you just have to enter to https://www.refworks.com/refworks2/?r=authentication::init and register.
It is a portal where you can import data base such as books, journals, articles... from archieves of Dialnet, Inspec, Academic search premier, and all the metasearchers from Web of Knowledge. (http://apps.webofknowledge.com)
It is a easy way of recopilate all those texts uploaded on the internet by creating new folders and subfolders, producing as well an administration of bibliographic importance.
The best app is the reference searcher; where you can search in the RefWork database using QuickSearch.
