Abstracting and indexing

Abstracting and indexing databases enhance the visibility and discoverability of scholarly content to the relevant research communities. BMJ works to ensure that our publications appear in a wide range of leading abstracting and indexing databases, as detailed on the individual journal about pages.

 
Directory of Open Access Journals

The DOAJ is an independent online database that indexes peer-reviewed open access journals covering many different academic disciplines.
https://doaj.org/

 
Google Scholar

Google Scholar is a freely accessible web search engine that indexes scholarly literature across an array of publishing formats and disciplines.

PubMed

PubMed is a database owned and maintained by the United States National Library of Medicine (NLM) at the National Institutes of Health (NIH).
https://pubmed.ncbi.nlm.nih.gov/

 
MEDLINE

MEDLINE is the premier bibliographic database of references and abstracts on life sciences and biomedical topics. If the journal you submitted to is indexed in Medline your article will be deposited to the PubMed database approximately 24 hours after online publication. PubMed will usually display the article within 48 hours after the deposit. Not all article types are indexed by within the PubMed database; meeting abstracts and book reviews are not included.

If the journal you submitted to is not indexed in Medline or PMC, you may post the Author Accepted Manuscript (AAM) to PMC after a 12 month embargo from issue publication. Please note that the final typeset article available on the journal’s website (the Version of Record) cannot be posted. Please review the full details on BMJ author self-archiving and permissions for further information.

 
PubMed Central

PubMed Central (PMC) is a free full-text archive of biomedical and life sciences journal literature. If the journal you submitted to is indexed in PMC, or if you have selected to publish your article as open access, your article will be deposited to the PMC database approximately 24 hours after online publication for continuous publication journals or after issue publication for periodical journals. PMC will usually display the article within 2-3 weeks after the deposit. Articles displayed in PMC are subsequently included within the PubMed database by NLM. Not all article types are indexed by within the PubMed database; meeting abstracts and book reviews are not included.

If the journal you submitted to is not indexed in Medline or PMC, you may post the Author Accepted Manuscript (AAM) to PMC after a 12 month embargo from issue publication. Please note that the final typeset article available on the journal’s website (the Version of Record) cannot be posted. Please review the full details on BMJ author self-archiving and permissions for further information.

 
NIH compliance
The National Institutes of Health (NIH) developed the NIH Manuscript Submission (NIHMS) system to facilitate the submission of peer-reviewed accepted manuscripts (AM) for inclusion in PubMed Central (PMC) in support of the NIH Public Access Policy. The NIHMS system allows users such as authors, principal investigators, and publishers to supply material for conversion to XML documents in a format that can be ingested by PMC. Depositing a manuscript in NIHMS for inclusion in PMC is a multi-step process, requiring an author to approve the deposited files and associated funding before conversion and the PMC-ready version after conversion.
 
BMJ now supports the initial deposit of NIH-funded AMs on behalf of authors and commits to depositing the peer reviewed AM to PMC within 1 week of acceptance for publication. Corresponding authors can then expect to receive further notification from PMC to complete the approval process of their peer reviewed AM within 1-2 weeks of acceptance. AMs are kept under a 12 month embargo.
