The ABMS Continuing Certification Reference Center™ replaces its Evidence Library™. The latter was revised to accommodate the broad and continually growing variety of literature and Internet resources relevant to the Board Certification community. While the format of the publicly accessible, web-based resource remains the same, new indexing and filtering options have been added that further divide the literature by study types and certification topics. Several hundred articles have been reviewed by ABMS staff and physician volunteers/consultants for inclusion in the Center. As a dynamic, evolving source of information, new references and annotations will be added to the Center over time and as new literature emerges.
