2000 Update Schedule for MEDLINE on
PubMed and Internet Grateful Med (IGM)
[corrected 1999/12/02]

  • In-process citations are added daily, Tuesday-Saturday. In-process citations are supplied electronically by publishers or are scanned and converted by optical character recognition, or are keyboarded in preparation for indexing.

  • Completed MEDLINE citations are added weekly, and are typically available by noon (U.S. Eastern time) each Saturday. Completed HealthSTAR citations are added to PubMed monthly, several days after the final weekly update of each MEDLINE Entry Month. Completed MEDLINE citations contain MeSH Heading, Publication Type and other information added during the indexing process, and have undergone further quality control. Searchers should note that completed MEDLINE citations are rarely new to PubMed, but rather, they replace existing citations in PubMed that are tagged "MEDLINE citation in process."

  • MEDLINE citations in the Update Schedule are organized by Entry Month, which refers to the monthly issue of the hard copy Index Medicus in which they will be printed. MEDLINE Entry Month is not directly searchable in PubMed. For techniques on how to limit to citations recently added, see the May-June 1999 NLM Technical Bulletin article, Converting SDI searches to PubMed at As this article explains, running a search in PubMed and limiting the Entrez Date to the last 30 days does not equate to the date range of the SDILINE file.

    The last paragraph of this article discusses the proposed PubMed "Cubby" service that will offer a SDI-like capability. This new service is still under development although tentative plans call for an additional date field that will change when a PREMEDLINE record is elevated with MeSH Headings to MEDLINE.

NOTE: This schedule only goes through May 2000, as NLM expects to be in transition to a new data creation and maintenance system which may affect the update schedule.
