Connotea [1] is a free online reference management and social bookmarking service for scientists created by Nature Publishing Group [2]. While somewhat experimental in nature, Connotea already has a large and growing number of users, and is a real, fully functioning service [3]. The label 'experimental' is not meant to imply that the service is any way ephemeral or esoteric, rather that the concept of social bookmarking itself and the application of that concept to reference management are both recent developments. Connotea is under active development, and we are still in the process of discovering how people will use it. In addition to Connotea being a free and public service, the core code is freely available under an open source license [4].
sperkins on 26 Nov 07"The apparent success of Internet-based social bookmarking applications begs the question of whether large enterprises or organizations would also benefit from social bookmarking systems. To investigate this question, at IBM we are designing and developing an enterprise-scale social bookmarking system called dogear. The rest of this article describes the design challenges and early lessons learned from a friendly trial of the technology."
