Non-MeSH
Indexed Citations
- Some of the
citations received electronically from publishers may never become
MEDLINE citations.
- These records
are not assigned MeSH terms because they do not go through the
indexing process.
- These records
may have either the status tag [PubMed] or [PubMed - as supplied by publisher] and remain in PubMed even though
they are not MEDLINE citations.
- There are
three sources of these types of records:
1. Out-of-scope
Articles from selectively indexed MEDLINE journals
- This may
occur when a particular article in a
selectively indexed journal is out-of-scope for MEDLINE (such as a geology
article in a general scientific journal like Science or Nature).
- These citations
have been reviewed for accurate bibliographic data.
- The status
tag [PubMed] appears on these citations.
2. Articles
from issues of journals published prior to selection for MEDLINE
indexing
- These earlier
citations will not be indexed with MeSH headings.
- Prior to
late 2003:
- the citations
were not reviewed for accurate bibliographic data
- the status
tag of [PubMed - as supplied by publisher] appears
- Beginning
in late 2003:
- the citations
have been reviewed for accurate bibliographic data
- the status
tag of [PubMed] appears
Example:
NLM began indexing the journal Molecular Diagnosis, with v.
4, no. 1, 1999. However, the publisher electronically supplied
NLM with citations from earlier volumes. The citations from
back volumes were entered into PubMed but will not be indexed
with MeSH.
Note: Indexing
information for a particular journal can be found in the “Indexed
In” field in the NLM
Catalog. Use PubMed’s Journals
Database to link to this information.
3. Articles
archived in PubMed
Central from non- MEDLINE journals
