AuthorClaim registration service

The PubMed collection


As stated on the PubMed homepage

PubMed is a service of the U.S. National Library of Medicine that includes over 17 million citations from MEDLINE and other life science journals for biomedical articles back to the 1950s. PubMed includes links to full text articles and other related resources.


AuthorClaim is licensed vendor of PubMed. But don’t worry, we are not selling anything, we just hold a licence that allows us to make the records available here. However, we don't hold the full records. There are about 2% of PubMed records that the NLM do not include in the PubMed distribution. Details are in the 2008 MEDLINE®/PubMed® Baseline Distribution documentation


PubMed comes as an annual baseline dataset as well as as number of patches that are released several times a week. We group records by the year in which they were created.

We are still in the process of loading PubMed baseline data into AuthorClaim. We load one year every day Monday to Friday.

For records created in the current year, patches are applied on Sundays. Records created in other year have to wait until we refresh records for the year concerned.

Once we get all of the past baseline data loaded, we can switch to a more speedy regime of patch inclusion.
