A few days ago I have downloaded and started to use Mendeley system. It is “free academic software for managing and sharing research papers”.
You can very easy create your own library on the Mendeley website and save online your pdf and Word (they are transformed to pdf during uploading) files.
You can acces them anywhere by using your name and password.
You can create folders in your library and easy reorganize – move files from one folder to other by drag-and-drop way.
You can create shared folders as well and invite your colleagues.
For more information read an interview with Victor Henning from Mendeley.
There isa large community of researchers and you can search the list of them by entering topic, e.g. “Knowledge management”. Today I have found 291 member who have research interest in knowledge management
Then you can contact them sending a message.
