As its name suggests, the Digital Reseach Tools (DiRT) Wiki is a collection of software and online services for researchers.
The site is edited by a group of academic librarians and researchers with diverse specialities and interests. Tools are organized by function (bookmarking, brainstorming, citation management, etc.) and relatively up-to-date, depending on the section (each page notes at the top when it was last edited).
Unlike Wikipedia, DiRT can only be edited by wiki members, who must be approved by the organizer, librarian Lisa Spiro. Check out the guidelines for contributors and consider adding a review of your favorite research tool.
