New PubMed® Field, Location ID Includes DOIs
i n [month/year TBD] a new field, Location ID, was added to PubMed® records. This field was created so publishers can include DOIs (Digital Object Identifiers) and PIIs (Publisher Item Identifier) in the source data of a citation.
On PubMed's non-tagged formats (e.g., Summary, AbstractPlus) DOIs will display at the end of the source - typically following the pagination or the PII (see Figure 1).
Location ID appears with the field tag LID in the MEDLINE format, and in the ElocationID element of the XML format. (See Tybaert S. MEDLINE Data Changes — 2008. NLM Tech Bull. 2007 Nov-Dec; (359):e6. for additional information.)
To search using a Location ID, enter the number in the PubMed search box with the search tag: [lid], e.g., to be determined [lid], or use Preview/Index to find the number in the Location ID index. The Single Citation Matcher may be modified in the future to use Location IDs.
Note: PubMed records will continue to include PIIs and DOIs in the Article ID field (see AID field on the MEDLINE format), if it is supplied by the publisher. This field is used to create links for the LinkOut program; it is not used to create citation source information.
