list of serials indexed

States Center of the ISSN Network. The ISSN is
irrevocably linked to the key title of the serial. If the
title of a continuing serial changes, a new ISSN must
be assigned to the new title. If a title is published in
both print and electronic format, there should be a
separate ISSN for each format. In the List of Serials
Indexed for Online Users, the ISSN is printed on the
third line of the entry, and the format corresponding
to each ISSN is designated by a parenthetical (P) for
“print” or (E) for “electronic” following the number.
More information about the ISSN is available at
http://www.issn.org.
PERMANENT PAPER NOTICE

unique identifier.

Management Section, National Library of Medicine,

NLM UNIQUE IDENTIFIER
The NLM unique identifier consists of either a
number with up to nine digits or an eight-digit
number followed by an alphabetic character. It is used
by medical libraries in reporting serial holdings data
to DOCLINE Serial Holdings (formerly called
SERHOLD ®), NLM’s database of machine-readable
holdings statements for serial titles held by U.S.,
Canadian, and Mexican biomedical libraries. The
unique identifier appears on the right-hand side of the
last line of each entry. In PubMed this number is
labeled as “JID” in the MEDLINE display format and
as “NLM ID” in the Entrez Journals database
(http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=J
ournals).
When requesting serial interlibrary loans from the
National Library of Medicine outside of DOCLINE®
(NLM’s automated interlibrary loan request routing
and referral system), please include the NLM call
number (or On Order or In Process notation) and the
NLM unique identifier.
Holdings information indicating what issues of a
title NLM owns and the NLM call number can be
found in NLM’s online catalog, LocatorPlus, at
http://locatorplus.gov. Indexing coverage and
detailed bibliographic records can be found at
LocatorPlus and the NLM Catalog, an Entrez
database, at http://www.nlmcatalog.nlm.nih.gov.
