There are four principal SHERPA services supporting work for open access information — RoMEO, JULIET, OpenDOAR and FACT:
- RoMEO provides information on publishers’ copyright contracts, as an advisory service for academic authors wishing to archive their work on line
- JULIET provides information on funders’ open access policies, as an advisory service for academic researchers wishing to check the requirements of their grants
- OpenDOAR is the global directory of open access repositories of academic materials (over 2,700 are currently registered)
- FACT is a service for UK-based authors to assist them in complying with open access policies from a number of UK-based research funders.
