JULIET is searchable by country, funders' name and funders' open access requirements. The information is updated by community contributions. For users already familiar with open access, JULIET presents an interesting comparative chart listing funders and their open access policies.
SHERPA, the maker of JULIET, also offers other tools, including FACT, which helps researchers verify if particular journals comply with their funders’ requirements for open access to research, and RoMEO, a service for authors and repository administrators that summarises publishers' copyright transfer agreements as they relate to archiving.
