Cases Database, BioMed Central's valuable new resource for the medical community, has now launched. Cases Database is a freely accessible and continuously updated search interface, developed by BioMed Central, which allows clinicians, researchers, teachers and patients to explore thousands of peer-reviewed medical case reports including content integrated from PubMed Central and publishers such as Springer and BMJ Group. By bringing case reports together, Cases Database adds value to individual reports, allowing comparison of similar cases, helping to highlight trends and patterns which may help researchers to develop hypotheses which can then be tested by systematic research. For more information please read our blog and follow us @CasesDatabase.
Discounted article processing charges are available to users of Cases Database submitting manuscripts to Journal of Medical Case Reports before 1st March 2013.
