Creation of Journal Source at NLM

Return to Web VersionPrinter-friendly Version

NLM concatenates the following elements to create the journal source:
<MedlineTA>. < PubDate>;<Volume>(<Issue>):<Pagination>. <ELocationID>.

The EIdType attribute associated with <ELocationID> is used to label the ID as either a pii or doi (e.g., pii: 18832). When there are both <ELocationID> EIdType = "pii" and <ELocationID> EIdType = "doi", <ELocationID> EIdType = "pii" is presented first. NLM does not use <ELocationID> EIdType = "pii" in the Source when <Pagination> is present.

In addition, various combinations of the attributes associated with <Article> and <ArticleDate> elements are used to indicate whether the PubDate displayed in the source represents a print or an electronic publication date, and whether or not an additional Epub or Print publication date notation is needed at the end of the source.

Note there is a space after <MedlineTA> and after the period following <Pagination> if <ELocationID> co-occurs with <Pagination>. The punctuation marks (periods, semicolon, and colon) are not found in the elements themselves as physical data but are added for display purposes by programming in NLM's search interface(s). NLM follows the national standard for the formatting of citations for display (American National Standard for Bibliographic References ANSI Z39.29-2005, developed and maintained by the National Information Standards Organization (NISO, Z39)).
