Technical Notes - e1
Remembering ELHILL - e2
The National Library of Medicine will discontinue its Z39.50 server to the MEDLINE data (back to 1966) and the PREMEDLINE data effective December 13, 1999. This server communicates with the ELHILL command language, mainframe online system which is being discontinued for billed public access on September 30, 1999. (Read the March-April 1999 NLM Technical Bulletin article announcing this demise online at: http://www.nlm.nih.gov/pubs/techbull/ma99/ma99_elhill.html) In consideration for those organizations that may be providing Z39.50 MEDLINE/PREMEDLINE access to their users, NLM will continue to support its server until nearly the end of the calendar year through the completion of the December 9912 (EM) update of MEDLINE data. In mid-December, NLM changes to the new indexing year using the new edition of Medical Subject Headlings, all of which would require significant changes to the Z39.50 server. There is no Z39.50 replacement currently planned for the MEDLINE data. NLM provides free Web access to all its databases and users have been encouraged to transition to the Web for more than a year. PubMed, Internet Grateful Med, LocatorPlus, and TOXNET on the Web provide free access using state-of-the-art search engines (http://www.nlm.nih.gov). Please direct questions to NLM Customer Service at: firstname.lastname@example.org.
The Print and Electronic Journals in MEDLINE Fact Sheet [This link has been removed because it is no longer valid] describes NLM's policy for indexing journals issued electronically or in print or in both media. For related information on this subject, please review the article in the March-April 1999 NLM Technical Bulletin, Citing Articles in Journals Published in Print and on the Web, (http://www.nlm.nih.gov/pubs/techbull/ma99/ma99_electronic.html).
Because ELHILL public billed access will terminate on September 30, 1999, there are several points to clarify about NTIS (National Technical Information Service) billing of ELHILL services.
These plans refer to ELHILL online services only. NTIS billing for DOCLINE services and MEDLINE licensees will continue.
At the end of July, the following search capabilities were added to PubMed:

Correction to the September-October 1998 NLM Technical Bulletin Article Titled MeSH Coming Attractions
The article titled MeSH Coming Attractions (http://www.nlm.nih.gov/pubs/techbull/so98/so98_mesh.html), as published in the September-October 1998 NLM Technical Bulletin contains the following erratum:
The text should read: Abstract was changed to Meeting Abstracts. The September-October issue has been corrected to show the plural form.
As announced in the May-June 1999 Technical Notes [http://www.nlm.nih.gov/pubs/techbull/mj99/mj99_technote.html#tri], the TRI97 (Toxic Release Inventory 97) file became available on TOXNET on July 21, 1999. On that day TRI87-94 and the TRIFACTS file were removed from TOXNET due to budget constraints. Please see the original technical note for more information about the TRI files.
The HealthSTAR ELHILL file configuration changed on July 29, 1999. In the new file configuration, HealthSTAR contains citations from 1992 forward and HealthSTAR75 contains citations from 1975-1991. Two years of data (1990-1991) were moved from HealthSTAR to the backfile, because the current file had run out of the space needed for the addition of new data. The messages you see when you connect to these files in ELHILL will NOT be changed, that is they will continue to show the past years of coverage.
The IGM HealthSTAR search screen year range pull-down menu has changed so that the current file shows the correct start date of 1992, rather then 1990.
