Full Record Fields


The full title of the article. All titles are in English. If a title was originally published in another language and translated, then the title is enclosed in square brackets ( [ ] ). For example:

[Hepatic eosinophilic abscess presenting as a single nodular mass]


Foreign Title

The vernacular title of the source publication in the original language (if the original language is not English). For example:

Title: [Use of sorafenib in patients with hepatocellular or renal carcinoma]
Foreign Title: Bon usage du sorafenib chez les patients pris en charge pour un carcinome hepatocellulaire ou un cancer du rein.

Note that non-Roman alphabet language titles are transliterated.



The author(s) of the source document. Author names appear as last name followed by a first name and/or initials. If no author names exists in the database, then this field contains the names of corporate authors.

All author names from the source document are provided in records from 1994 to the present. Prior to 1994, up to ten authors are shown, with "et al" in the tenth position. Full first and middle names (if published) will appear in papers published in 2002 to the present.

Records of publications with no author(s) or corporate names display Anonymous in the Author field. A record of a collection of meeting abstracts will display abstracts in the Author field.


Corporate Author(s)

The corporate or collective author of the source document.

Names of corporate authors always appear in the Corporate Author(s) field in MEDLINE records from 2001 to the present. In older records, the names of corporate authors may appear in the Title field.

     Corporate Author(s): Centers for Disease Control (CDC)

A brief summary or description of the essential content from the source document.

English-language abstracts are taken directly from the published article. If the article does not have a published abstract, the National Library of Medicine does not create one. Generally, there are no abstracts for records created before 1975. All abstracts are in English. Because data entry policies at NLM have changed over the years, abstracts in records created before 2001 may be truncated, in which case one of the following phrases may appear at the end of the text enclosed in parentheses.



Other Abstract

A small number of records contain abstracts written by a collaborating partner. These abstracts are not taken from the source publication.



Keyword List

Author keywords are provided by the author(s) of the source article. They are taken directly from the source article and are identified as keywords in the source article.


Author Information


The address of the of the first listed author of the source publication. The Address field includes the e-mail address of the author, if provided by the source publication.



Grant Information

The research grant or contract number (or both) that designates financial support by any agency of the United States Public Health Service or any institute of the National Institutes of Health.

Grant information was introduced in 1981.

A list of possible values is available in PubMed help at:

Note: Although NLM enters the grant number, the acronym and agency values are derived by using a machine algorithm against the grant number. This may result in some inaccurate derivations, but the overall benefit of supplying the separate acronym and agency was considered to be worth the risk of some inaccuracies.


Categories / Classification

Research Areas

Research area of the source document. This field may contain more than one research area.


MeSH Terms

Subject headings and qualifiers from the MEDLINE Thesaurus. If a term is marked with an asterisk (*), it is a major topic of the source document.



This field contains the names of drugs and other chemical substances from the Chemical Thesaurus.

The Registry Number column contains a unique five- to nine-digit number in hyphenated format assigned by the Chemical Abstracts Service to specific chemical substances. For enzymes, the Enzyme Commission number derived from Enzyme Nomenclature.

The Name column contains the name of the substance that the registry number or the EC number identifies.


Document Information

The selected language of the source document.


PubMed ID

A unique identification number assigned to each record in MEDLINE.


NLM Unique ID

The alpha-numeric identifier for the source publication that was assigned by NLM's Integrated Library System, LocatorPlusTM at


Date Created / Date Completed

Date Created is the date the record is created, before full indexing and validation.

Date Completed is the date assigned to the record after full indexing and validation.


Date Revised

Date Revised is the date when change(s) to a fully indexed and validated record are made.

The International Standard Serial Number is a unique eight-digit number that identifies periodical publications such as journals and electronic publications. If a journal has both a print ISSN and an electronic ISSN, then both display. The format is four numbers, a hyphen (-), three numbers, and then a check character that may be a number or X. Example: 1367-4803

Journal Information

Table of Contents: Current Content Connect®

This field contains a link to the Current Contents Connect® Browse Journals page where you can browse the table of contents of journals and books covered by the editions and collections to which you subscribe in Current Contents Connect.

Performance Trends: Essential Science IndicatorsSM

This field contains a link to Essential Science Indicators where you can perform in-depth analysis to find data for ranking scientists, institutions, countries, and journals. With Essential Science Indicators, you can:

  • Explore science performance statistics and science trends data, based on journal article publication counts and citation data
  • Determine research output and impact in specific fields of research
  • Evaluate potential employees, collaborators, reviewers, and peers

Impact Factor: Journal Citation Reports®

The Journal Impact Factor is defined as all citations to the journal in the current JCR year to items published in the previous two years, divided by the total number of scholarly items (these comprise articles, reviews, and proceedings papers) published in the journal in the previous two years.

Though not a strict mathematical average, the Journal Impact Factor provides a functional approximation of the mean citation rate per citable item.  A Journal Impact Factor of 1.0 means that, on average, the articles published one or two years ago have been cited one time.  A Journal Impact Factor of 2.5 means that, on average, the articles published one or two years ago have been cited two and a half times.  The citing works may be articles published in the same journal.  However, most citing works are from different journals, proceedings, or books indexed in Web of Science Core Collection.

Citation Network

Times Cited

The Times Cited count displays the total number of times a published paper was cited by other papers within our database products such as Web of Science Core Collection and BIOSIS Citation Index . The link takes you to a Citing Articles page in one of our citation indexes.

Access to records is limited to your institution's subscription.


Cited References

The Cited References count displays the number of documents cited by the current record. Click the link to view the list of cited references. From there you can view the full record of each cited reference. (Access to the full records of cited references may be limited to your institution's subscription.)


To view records that share cited references with the record you are viewing in the current product database, click the View Related Records link.

The assumption behind Related Records searching is that articles that cite the same works have a subject relationship, regardless of whether their titles, abstracts, or keywords contain the same terms. The more cited references two articles share, the closer the subject relationship.

The link displays the total number of related records within one of our citation indexes such as Web of Science Core Collection or BIOSIS Citation Index .

Access to records is limited to your institution's subscription.
