A web browser plug-in supports a team approach to Internet research. An initial search, preferably by a web robot, generates an initial plurality of potentially relevant URLs, which are stored in a shared URL database. Team members are notified when new URLs are added to the database. Team members, optionally through an access control system, evaluate and rank the URLs for relevance. URLs are managed based on their rank, such as ordering their display and deleting non-relevant URLs. The rank of a URL may be indicated visually in a web browser, such as by displaying graphic icons adjacent its title. The method may be iterative, with additional searches conducted, preferably via additional web robots, with the additional URLs returned being evaluated, ranked, and managed in the URL database.
