The RRID is a Persistent Unique Identifier assigned to help researchers cite key resources (antibodies, model organisms, and software projects) in the biomedical literature to improve transparency of research methods. They are machine readable, free to generate and access, and consistent in format across publishers and journals. They are meant as a tool to improve scholarly communication and scientific reproducibility.

RRIDs are created by authoritative databases such as the Antibody Registry, Addgene, or Cellosaurus and their aggregation is supported by SciCrunch. This aggregation provides one place for journals to send authors and there are clear instructions, a “cite this” button next to each resource and a help desk. Over 100 journals have guides on how to use RRIDs and over 1000 have published RRIDs at the time of this document.
