PubMed: Have You Noticed More "In Process" Citations than Usual?

What's the deal? Are your Cubby searches finding fewer new citations than you expect? Why are there so many "in process" citations in your PubMed retrieval? It's "that time of year," the period when NLM staff are busy with end-of-year processing. During the next few weeks all 12 million MEDLINE citations will be reviewed, to update their MeSH descriptors with the 2003 vocabulary and make other changes system-wide. This processing is accomplished as quickly as possible, but generally extends through November and December. New "in process" and "as supplied by publisher" citations will continue to be added to PubMed daily. However, during the end-of-year processing period, newly completed, indexed citations are not upgraded to full-fledged MEDLINE status. For the next few weeks, they will remain in PubMed as "in process," i.e., without MeSH, publication type, subset, and other indexing-supplied information. To include the most recent information in your retrieval, do not use affected field qualifiers. If your stored Cubby strategy includes a qualifier such as MeSH or publication type, you may find no new records during this period. See the NLM Technical Bulletin article at http://www.nlm.nih.gov/pubs/techbull/so02/so02_endofyear.html for all the details.
