MEDLINE Publisher: New file on legacy Dialog

MEDLINE^® Publisher (File 152), new on legacy Dialog, contains records with a status of “Publisher” extracted from the National Library of Medicine (NLM) PubMed database.

A “Publisher” record in PubMed is an initial version of a record prior to its distribution by NLM as a MEDLINE record. These records subsequently change status in PubMed to “In Data Review.” When the status changes in PubMed, the records are supplied by NLM for the first time as MEDLINE records and are added to legacy Dialog MEDLINE Files 154 and 155. Until now, the Publisher status records have not been available on legacy Dialog.

Now you can set up daily Alerts in File 152 to obtain the earliest version of NLM records destined for MEDLINE. Many Publisher status records are for articles published on the Web in advance of a journal issue’s release (i.e. ahead of print citations) that may not have the journal issue, volume or pagination assigned. Publisher records also do not contain descriptors, identifiers or CAS^® Registry Numbers.

MEDLINE: NLM prepares for 2013 reload

Preparation for the annual reload of MEDLINE^® on Dialog (Files 154,155) is underway. MEDLINE is reloaded every year because the National Library of Medicine (NLM) re-indexes relevant documents from the whole database with changed medical terms. Toward the end of November, the NLM provided updates that contained only RT=IN PROCESS and RT=IN DATA REVIEW records (no RT=COMPLETED records with Descriptors). In mid-December there will be a hiatus in the updating of MEDLINE on Dialog while adjustments are made to install the 2013 thesaurus after which daily updating will resume.
