Novel forms of scholarly communication such as collaborative information sharing technology are evolving gradually. This may be the beginning of a more significant transformative change, particularly in sharing information within laboratories or groups or among multisite collaborations. Many professors have begun utilizing blogs, wikis and multimedia (e.g., YouTube) to communicate with their colleagues
Of course this article covers more than just the collaboration aspect of their work. It is interesting to see how scientists at the various institutions read, share, use and store their academic content.
