Internet Grateful Med® Update

Internet Grateful Med Version 2.3 with the added databases: AIDSDRUGS, AIDSTRIALS, DIRLINE, HISTLINE HSRPROJ, OLDMEDLINE and SDILINE, became available online on July 23, 1997. These databases joined MEDLINE, PREMEDLINE, AIDSLINE and HealthSTAR to bring the total number of databases on Internet Grateful Med to 11.

The AIDSLINE database was updated on August 1, 1997 with 126 additional abstracts from the 11th International Conference on AIDS. The SI value for these citations is ICA11 and the Entry Month (EM) value is 9709.

While the bulk of the abstracts from this conference were entered into AIDSLINE and put on the Web in January 1997, these 126 late breaking abstracts were not indexed and loaded into AIDSLINE until August 1997.

Location Codes to be Deleted from SERLINE®

The following fields will be removed from SERLINE effective with the October 1997 update:

Regional Locator Codes (L1-L8)

Regional Locator Counts (K1-K8)

Region (RG)

The data in the SERLINE locator fields is no longer current and will not be updated due to technical constraints. Current holdings information is available via SERHOLD(TM), which serves as the basis for DOCLINE®, NLM's online interlibrary loan request and referral system for health sciences libraries. Descriptive information about libraries and other organizations which use NLM's Interlibrary Loan (ILL) services or are a part of the Regional Document Delivery Network is provided by the DOCUSER (DOCUMENT DELIVERY USER) database.

Expansion of Copy Cataloging

In June 1997, the Cataloging Section began using OCLC member records in copy cataloging of monographs and serials. This practice represents an expansion of copy cataloging, particularly for monographs, where NLM previously relied solely on copy available from the Library of Congress and the U.S. Government Printing Office. This expansion was made possible by the implementation of new NLM designed software which uses the OCLC Z39.50 client/server interface under an agreement with OCLC, Inc.

Users have been able to see bibliographic records for which NLM has provided copy cataloging based on OCLC member copy in its regular USMARC record distribution since July 3, 1997. In conformance with USMARC record content designation, any such records distributed to NLM licensees may be easily recognized by the coding of the USMARC field 040 (Cataloging Source).

NTIS To Charge $5.00 Per Quarter for Deposit Accounts

In June, the National Technical Information Service (NTIS) notified all Deposit Account holders that effective July 1, 1997, NTIS was imposing a $5.00 quarterly service charge ($20.00 annually) for all Deposit Accounts. This includes those used for MEDLARS searching, or for other purposes (ILL, ordering government documents, etc.). Quarterly Deposit Account statements reflecting MEDLARS account activity for July, August, and September 1997 will carry this $5.00 service charge. NLM urges you to consider changing to either free MEDLINE via Web-based PubMed or Internet Grateful Med or changing your billing method to credit card payment to avoid these service charges. You must notify NTIS in writing to close your account, and request a refund of funds deposited, and/or to switch to credit card billing. Please include your NTIS Deposit Account number and the name on the account in your letter; this information can be found on the NTIS invoice. You may send your written notification in one of the following ways:

Surcharge Eliminated

For many years the Library has charged foreign users, as non-U.S. taxpayers, a surcharge that represents their proportional share of the costs of creating the databases. The surcharge has applied to users of the NLM databases whether access was direct to NLM from outside the U.S. or through MEDLARS licensees who provided products or services to users outside the U.S.

The Library recently reviewed its pricing policies in relation to the worldwide free Web access and the spirit of the U.S. Government's Administration's Global Information Infrastructure. That initiative encourages use of the Internet on a global basis. The Library has therefore decided that effective October 1, 1997 to discontinue charging users or licensees a foreign surcharge and urges all licensees to remove NLM's foreign surcharge from their pricing.

The ELHILL and TOXNET "SHOW COST" command displays will be changed to reflect this reduction in cost. Please watch the Online News and Broadcast for an announcement of when the change will be implemented online; it will likely take place sometime around October 1, 1997. Regardless of the date of the online announcement, all billed usage on non-Web based MEDLARS databases will exclude the surcharge portion in the actual invoices, effective, October 1,1997 forward.
