You pay only for the actual costs of searching the databases. For example, a five-minute search on MEDLINE may cost $2.00 including Telecommunications charges (based on an average cost of $22/hour for MEDLINE during prime time). You can print citations on your printer or have them printed overnight at the National Library of Medicine and mailed to you the next day. These "offline prints" cost you $0.18 per page for most databases. A typical page contains eight or nine citations without abstracts and two or three citations with abstracts. Average cost of most MEDLARS databases is $15/hour non- prime time; $22/hour prime time. Offline prints are $0.18 per page. Fees for the toxicology databases, which include royalties, range between $48 and $95/hour, with offline prints charges between $0.41 and $0.66 per page. MEDLARS® access gives you MEDLINE, the world's leading bibliographic database of medi- cal information, covering nearly twenty years and over 3,000 journals. The most sought-after database in medicine, it contains the informa- tion found in the publications Index Medicus, International Nursing Index, and Index to Dental Literature and is available on many online systems. Each article in MEDLINE is carefully analyzed and indexed by the National Library of Medicine (NLM) using MeSH® (Medical Subject Headings), NLM's 15,000 term medical language thesaurus. In addition to MEDLINE, as a MEDLARS user you have access to specialized databases in the fields of Health Administration, Toxicology, Cancer, Population Studies, Medical Ethics and more. A complete list of database descriptions appears at the back of this brochure. Connect In Seconds The equipment you need to access the MED- LARS system is rapidly becoming standard in almost every hospital, medical library, clinic and doctor's office. All you need is a terminal or microcomputer with telecommunications soft- ware, a modem, a telephone line and a printer. Nearly all equipment brands currently available can be used. Once you have applied for and received a MEDLARS User ID Code, it's as easy as dialing a local phone number and making a connection.

MEDLARS EDLIIE Databases The following case has been adapted from a reported case in NLM's files: A resident at a hospital in the midwest is faced with a sudden emergency. Lightning has struck a baseball field and three young boys are brought to the hospital in different stages of injury. The resident turns to MEDLINE. She begins her search using the MeSH Main Heading LIGHTNING, and precedes it with an asterisk to indicate that she wants only articles in which lightning is the main point. & She refines it further by specifying articles on CHILD (ages 6-12) and ADOLESCENCE (13-18) and only in ENGLISH. Five articles are retrieved from the current file. She prints out the citations and the abstracts. The titles and abstracts give her some basic infor- mation and she decides to examine two articles further. These she finds in the hospital library. Less than an hour after the boys' arrival, she is ready to begin treatment. WELCOME TO THE NATIONAL LIBRARY OF MEDICINE'S ELHILL RETRIEVAL SYSTEM.

Records for MeSH Headings include the scope of the heading, its position in the MeSH hierarchical structure, the date it became a heading, previous indexing notes, as well -- MEDLARS as additional information useful in indexing and searching. Records for Subheadings include descriptions of their use as well as indications of which categories of MeSH Headings they may be used with. Chemical Term records contain in- formation including systematic name, synonyms, phar- macologic action, CAS Registry Numbers and enzyme codes, for chemicals occurring in MEDLINE but which are not MeSH Headings. Name: NAME AUTHORITY FILE (Short form: NAF) Subject: Authority records for over 185,000 names, series, and uniform titles used as headings in bibliographic records resident in CATLINE and AVLINE.

Name records provide detailed infor- mation on a name, the name's relationship to other names, as well as cross-references. The series authority records provide information on NLM's treatment of a series; cross- references and notes are also provided whenever applicable. Since 1981, all names used in cataloging have complied with Anglo-American Cataloging Rules, 2nd ed. (AACR2), and many existing names have been reevaluated to agree with AACR2 form. AACR2 names identified in the NAF comply with national standards and may be used in a bibliographic record.

Location symbols for approximately 150 resource and selected major biomedical libraries in the RML Network appear for about one-third of the titles in the file. SERLINE is used as the journal authority file to MEDLINE, POPLINE, and HEALTH for the serial titles which are indexed for these databases. The List of Journals Indexed in Index Medicus, and Index of NLM Serial Titles, and the List of Serials Indexed for Online Users are produced from SERLINE. Health Sciences Serials is a quarterly microfiche edition of the SERLINE file. TOXNET (TOXicology data NETwork) TOXNET is a computerized system of toxicologically- oriented databanks operated by the National Library of Medicine as part of the MEDLARS system. This mini- computer based system includes a variety of modules used by NLM to build and review records. For outside users, TOXNET offers a sophisticated search and retrieval pack- age, which permits efficient access to valuable data, drawn from numerous sources, on toxic and otherwise hazardous chemicals. Currently operating on TOXNET are the follow- ing three files: CCRIS (Chemical Carcinogenesis Research Information System) CCRIS is a scientifically evaluated databank developed and maintained by the National Cancer Institute (NCI), con- Name: TOXLINE (TOXicology information onLINE) Subject: Bibliographic citations covering the toxicological, pharmacological, biochemical, and physiological effects of drugs and other chemicals.
