he National Library of Medicine<sup><font size="-2">®</font></sup> (NLM<sup><font size="-2">®</font></sup>) is now involved in MEDLINE year-end processing activities. These include changing the Medical Subject Headings (MeSH<sup><font size="-2">®</font></sup>) on existing MEDLINE citations to agree with the 2004 version of MeSH, and other global changes such as changes to Supplementary Concept Substance Names. Check the next issue of the <em>NLM Technical Bulletin</em> for an article about 2004 MeSH changes.
|

</p>

|
During end-of-year activities, NLM's schedule for adding indexed citations to MEDLINE and PubMed is temporarily interrupted. Once the end-of-year activities are complete (tentatively targeted for December 2003), the normal MEDLINE/PubMed update schedule will resume, and PubMed will use 2004 vocabulary in the MeSH translation tables and MeSH database, as well as in the citation data. According to the normal MEDLINE/PubMed update schedule, MEDLINE citations are released and revised Monday through Friday, and these citations are then available to MEDLINE licensees and PubMed users Tuesday through Saturday.
|
|
</p>
|
|
|
|
<p>
|
|
<strong>Indexed Citations</strong><br />
|
|
On November 13, 2003, NLM expects to halt temporarily the addition of new, fully-indexed MEDLINE citations to PubMed. NLM indexing staff will continue to index citations, but these records will be held and not added to PubMed until the normal update schedule resumes.
|
|
</p>
|
|
|
|
<p>
|
|
<strong>In-Process Citations</strong><br />
|
|
During end-of-year activities, "in-process" citations will continue to be added to PubMed. As a result, the number of PubMed records labeled [PubMed - in process] will temporarily increase. These citations do not have MeSH terms, but NLM performs issue level and subsequent citation level quality control reviews that are released to PubMed in advance of the MeSH headings being added.
|
|
</p>
|
|
|
|
<p>
|
|
<strong>Searching</strong><br />
|
|
A search limiting terms to fields affected by indexing (e.g., robotics [mh] AND review [pt]) does not retrieve in-process or publisher-supplied records (see <a href="#fields">list of fields added, changed, or supplemented during indexing</a>).
|
|
Therefore, during end-of-year activities when we are not adding completed, indexed citations to MEDLINE/PubMed, such searches–including those stored in the Cubby–may not retrieve new records for some weeks. To retrieve new, in-process records during this time, you should avoid limiting searches to affected fields (e.g., robotics review). Note that the search terms are not tagged in this example.
|
|
</p>
|
|
|
|
<p>
|
|
By December, the in-process citations that are within the scope of MEDLINE and that have been indexed since November 12, 2003 will be replaced as indexed citations with 2004 MeSH terms, Publication Types, etc. Searches, including Cubby Stored Searches, containing tagged search terms will then retrieve all applicable MEDLINE records.
|
|
</p>
|
|
|
|
<p>
|
|
<strong>Corrections on Hold</strong><br />
|
|
Also as of November 13, 2003, corrected citations for MEDLINE journals (e.g., because an author name was misspelled) will not be released to MEDLINE. NLM staff continue to correct completed citations and these will replace the incorrect citations in MEDLINE when the normal update schedule resumes.
