"Zotero is an easy-to-use yet powerful research tool that helps you gather, organize, and analyze sources (citations, full texts, web pages, images, and other objects), and lets you share the results of your research in a variety of ways. An extension to the popular open-source web browser Firefox, Zotero includes the best parts of older reference manager software (like EndNote) - the ability to store author, title, and publication fields and to export that information as formatted references - and the best parts of modern software and web applications (like iTunes and del.icio.us), such as the ability to interact, tag, and search in advanced ways. Zotero integrates tightly with online resources; it can sense when users are viewing a book, article, or other object on the web, and - on many major research and library sites - find and automatically save the full reference information for the item in the correct fields. Since it lives in the web browser, it can effortlessly transmit information to, and receive information from, other web services and applications; since it runs on one's personal computer, it can also communicate with software running there (such as Microsoft Word). And it can be used offline as well (e.g., on a plane, in an archive without WiFi)."

"Pearltrees lets you keep at hand the web pages you like, discover some new ones in your areas of interest and share them easily with your friends."
"The Virtual Heteroglossia is collaborative research tool that has been created to support practitioner-researchers, re-situate research activity within their established design enquiry. It helps them establish linkages between their work and other works in the field, in a manner that is sympathetic to the concerns of creative practice.
The Virtual Heteroglossia has been trialled in an undergraduate programme at The Queensland University of Technology in Brisbane, Australia in 2004. The trial was undertaken as part of a general effort to support students with the evolution of their research enquiry and the establishment of peer discussion networks.
The design of the tool has been modelled on the popular Weblog technology because of its ease of use and commonly understood affordances. Contributors using the tool collaboratively assemble and contest a shared collection of exemplar works. The collection is able to evolve over the course of a project to establish a common knowledge repository and shared conceptual reference."
