Year-End Processing

MEDLINE® and MEDLINE Backfile ELHILL Configuration - 1999

During 1998 Year-End Processing, all citations published in 1995 or earlier will be pulled from MEDLINE and placed in the appropriate ELHILL Backfiles. The MEDLINE "front" file on ELHILL will cover 1996 forward and the 1995 citations will be moved into MED93. The primary dates of coverage for MEDLINE and its Backfiles on ELHILL for 1999 will be as shown below effective December 14, 1998:

Reminder to searchers: PubMed searches MEDLINE, PREMEDLINE® and all Backfiles at one time. Internet Grateful Med 2.6.1 now uses PubMed to search MEDLINE. So searchers who use the IGM and PubMed interfaces do not need to remember the Backfile configuration, because their searches will be run against the complete file unless they choose to limit to a particular year or range of years.
