Til ley Bethesda, Maryland 20014 301/496-6193 -2- NLM TECHNICAL BULLETIN - JAN 78 TECHNICAL NOTES PLEASE QUERY THE ON LINE NEWS FILES DAILY AT NLM FOR SPECIAL NOTICES AND MESSAGES Whenever applicable, the headings of each Technical Note will Include a reference to the section/page of the NLM On-line Services Reference Manual which is consid- ered roost relevant to the item being discussed (e.g., Manual I1-9). Users should keep 1n mind that the item may pertain to other sections of the Manual. TRAINING - In order to avoid conflicts with Federal holidays, the dates of two on-line services training classes have been changed: From Oct 9-13, 1978 to Oct 2-6, 1978 From Nov 6-10, 1978 to Oct 30-Nov 3, 1978. The complete schedule of training classes appeared in the July 1977 Technical Bulletin. SERLINE - An entry of "SER" in the Abstracting and Indexing field (AI) (Manual X) of SERLINE indicates that the journal was in the original group of 6,500 SERLINE journals. CHEMLINE If, while in the CHEMLINE file and attempting a "PRINT DETAILED, (Manual XIV) the message "CAN XXXXXX CONTAINS NONE OF THE ELEMENTS SPECIFIED" is received, the detailed unit record is too long for printing in the detailed format. To get around this message, do a "PRINT INCLUDE and specify the fields you want printed.

The on-line files have been updated to reflect this change. INDEXING - ACTION POTENTIALS, EVOKED POTENTIALS, MEMBRANE POTENTIALS - Indexing policy has changed. Please change the annotations in your MeSH to read NIM instead of IM. - TECHNICAL NOTE 231 - On page 13 of the September 1977NLM Technical Bulletin it was incorrectly stated that all previous indexing Technical Notes, through number 231, are available through NTIS. Technical Note 231 is no_t available through NTIS and is included with this bulletin as Appendix A. MEDLINE - BACK75 (Manual VII) - The BACK75 file of MEDLINE was created and made available to users via the "OFFSEARCH command on December 19, 1977. The file contains (1) citations with an entry date from 741205 through 751108 or (2) citations which have a 1975,or earlier, year of publication (YP), regardless of entry date. - (IM) DATA ELEMENT - This is a reminder that searchers should use the (IM) data element, not the (ED) data element to limit retrieval to a specific month(s). For example: (1) to re-create October 77 SDILINE: SS 1 /C? USER: 7710* (2) to search only 1977 input: SS 1 /C? USER: 7701 OR 7702 OR 7703 OR 7704 OR 7705 OR 7706 OR CNT 1 USER: 7707 OR 7708 OR 7709 OR 7710 OR 7711 OR 7712* The (IM) data element was added to the records beginning with July 76 input. If segments of the file are needed before this date, call the MEDLARS Management Section Service Desk for entry dates. *Note: the qualifier (IM) is not required - NEW SPECIAL LIST C - Because of its importance to the program goals of the National Institute of Neurological and Communi- cative Disorders and Stroke, citations to certain literature that has not been accepted for Index Medicus will be indexed and input to MEDLINE as special list material. Because it relates to communication disorders, this will be designated Special List C. At the outset, this will include only eight journals starting with 1978 issues. -4- NLM TECHNICAL BULLETIN - JAN 78 TOXLINE/TOXBACK REGENERATION Sharon L. Valley, Ph.D. Specialized Information Services The TOXLINE/TOXBACK files are 1n the process of being regenerated. When completed, TOXLINE will contain Information from 1974 secondary sources forward, representing approximately 380,000 documents. TOXBACK will contain Information from secondary sources prior to 1974 and will contain approximately 350,000 documents. It 1s anticipated these files will be available by March 1, 1978. There will be some changes 1n the unit record description for the regener- ated TOXLINE/TOXBACK. Specifically, these changes are: 1. Page number (PG) will be eliminated as a separate, searchable element. The pagination will still print as part of the Source (SO) field. 2. Medical Subject Headings (MH) will not be directly searchable as (MH). They will, however, be textracted Into unlterms and be searchable as text words (TW),I.e.: (TW) THIN AND LAYER AND ALL CHROMATOG: Instead of (MH) CHROMATOGRAPHY, THIN-LAYER. 3. Medical Subject Headings Tree Numbers will not be Included 1n TOXLINE, since the vocabulary changes are not "file maintained" each year. This means users will not be able to EXPLODE MeSH terms or tree numbers 1n TOXLINE. The term(s) should be entered as text words (TW) Instead. 4. The year of publication (YP) will not be rangeable, but will be searchable as Individual years, I.e., a user maylimit a search to papers published 1n either 1976 or 1977, by entering: CORRECT 5 AND 76 OR 5 AND 77 where 5 equals search statement 5. Users will not be able to enter: INCORRECT 5 AND FROM 76 TO 77. The correct example 1s a more efficient use of the computer system for this type of query. The latter type of search would be more time consuming, therefore the ranging file for "year of publication" was not created. -5- NLM TECHNICAL BULLETIN - JAN 78 5. The source and time frame field (ST) will be 4 digits, and searchable, (YYMM as year month) I.e. 7G04 for the 1978, April update. 6. In the material supplied by Chemical Abstracts Service (CAS) there will be additional Chemical Abstracts Service Registry Numbers (RN), which were CAS Indexing Information but not Included In the earlier version of TOXLINE. These additional CAS Registry Numbers will appear 1n the searchable RN field, even though the chemical(s) may not be mentioned 1n the title or abstract, but do appear 1n the original document. 7. On an experimental basis, a new searchable field will be created that will contain unlterms from the title field (TI), andunlterms from the keyword field (KW) which are the Index terms from TOXBIB, IPA, etc. This newfield will have the search mnemonic of (KW). This field could be used If a searcher wants terms primarily In either titles or keywords, and not the abstract.
