This resource is continually developed as additional references, links, and downloadable files become available for inclusion.
Note that the American College of Rheumatology is not the originator of many of these disease activity measures, indices, questionnaires, and criteria. Inclusion of a reference in this bibliography should not be construed as an endorsement by the ACR, except as indicated otherwise. This bibliography is not intended to be exhaustive; however, new references will be added from time to time.
