Book availability as a performance measure of a library: an analysis of the effectiveness of a health sciences library.

User satisfaction as a measure of library effectiveness has been studied by using Kantor's branching technique. Cleveland Health Sciences Library, Cleveland, Ohio, was used as the center of this study. The study measured independently the user bibliographic information performance, collection development policy performance, acquisition policy performance, user catalog performance, circulation performance, library operation/functioning performance, and the user search performance. Each of these categories represented one or more of the factors of library performance that could account for the possibility of users' failure. The sample size consisted of 1000 requests for book titles. The book availability rates were 59.60% without the help of the librarian and 63.50% with the help of the librarian. The results indicate that a dynamic study of library policies at regular intervals by using the Kantor's method, which is easily reproducible, can maximize library resources for the most effective fulfillment of user demand.

Mechanization of library procedures in the medium-sized medical library. 8. Suspension of computer atalog.

A system for the substitution of a computer-printed book catalog for a card catalog was put to the test by making the former the sole means of locating material in the library, after four years of being used merely as an adjunct to the card catalog. It was found not suitable, and a new system is being devised in the light of the difficulties encountered. The reasons why the system broke down and the plans for the new one are described.

Time-shared computing. Implications for medical libraries.

Many library data processing systems are unresponsive to the needs of librarians because of the necessity to batch-process transactions in a computer center. Such systems tend to be reportoriented rather than information-oriented with resultant problems in the timeliness of information. Time-shared computing permits multiple users to process jobs simultaneously through on-line interaction with the computer. Such systems offer to the librarian the advantages of immediate access to information, costs shared with other users, and direct man-machine interaction. This tutorial paper describes time-shared systems with applications in the library. Problems concerning the cost and present state-of-the-art of time-sharing are discussed.

MECHANIZATION OF CATALOGING PROCEDURES.

The Columbia-Harvard-Yale Medical Libraries Computerization Project has put into operation its mechanized procedure for the production of catalog cards. Cards produced are in final form ready to be filed into a card catalog. Catalogers prepare copy on a worksheet from which punched cards are punched. An IBM 1401 computer processes the decklets of punched cards on magnetic tape to produce the expanded decklets of punched cards needed to print the various packs of catalog cards required to go into different catalogs. Next, the computer punches the expanded decklets of cards to operate an 870 Document Writer, which types out the catalog cards in final form. Cost of cards ready to file is 12.5 cents per card.

Through the looking glass: finding Internet sites to mirror your collection.

Many libraries are grappling with the new freedom to link to the Internet directly from a Web-based catalog. A conservative approach that locates only Web sites replicating a library's print holdings is described. Methods for locating URLs include reviewing front matter in reference materials, scouring the Internet for material produced both in print and full text on the Web, electronic mailing lists, publishers' promotional materials, conferences, and journal articles. Readers are encouraged to make links from the catalog to any original material produced in Web-readable form by the university, including dissertations and conference proceedings.

Three-way division combined with conversion to Medical Subject Headings(MeSH) in a medium-sized medical library.

Conversion to MeSH and other reasons are enumerated for the division of an undivided dictionary card catalog into a three-way divided catalog, consisting of Proper Names, Titles, and Topical Subjects sections. Methodology of division is described. Conversion from Library of Congress Subject Headings to Medical Subject Headings (MeSH) as an authority list stimulated such concurrent changes as (1) the introduction of a guide card system that eliminates typing of subject headings on catalog cards and (2) the adoption of a filing system that employs reverse chronological order for all types of sequential material in the Proper Names and Titles sections and for all material in the Topical Subjects section. The ancillary decisions, procedures, and methods necessitated by these major conversions are also described.

Low cost organization of a mental retardation facility staff library.

A mental retardation facility staff library of 700 volumes required complete organization. Two restraining factors were lack of personnel and limited funds. A plan was developed to classify titles according to Library of Congress, with the subject heading catalog predominantly based on Medical Subject Headings (MeSH). A cataloging service was located which produced custom card sets and book labels from CATLINE and MARC computer databases. Where necessary, MARC records were edited to alter LC subject headings to MeSH terminology. Organization was accomplished at an average cost per title of less than $1.50.

The NEOUCOM Cooperative Cataloging Service: development and review of the first four years.

The Basic Medical Sciences Library of the Northeastern Ohio Universities College of Medicine (NEOUCOM) provided a Cooperative Cataloging Service to fourteen of its affiliated hospitals' libraries since March 1978, using the OCLC system. Analysis of the first four years of service showed that the hospital libraries spent almost $30,000 to catalog more than 18,000 titles. Personnel expenses and other costs eclipsed the savings from a 31.3% duplication rate. Centralized bibliographic control control and the principal by-product of the service, a uniform, machine-related data base, provided the foundation for an on-line integrated library system to serve the consortium. The hospital libraries contributed 44% of the unique titles in this data base, which emphasis the need to share resources and continue cooperation.

Bone marrow stem cell protection from chemotherapy by low--molecular-weight compounds.

The stem cells of the bone marrow have the capacity for both self-renewal and derivation of all the blood cell lineages. Consequently, toxicity to these cells can result in neutropenia, agranulocytosis, thrombocytopenia, pancytopenia, or aplastic anemia. Many anticancer drugs adversely affect the bone marrow, and neutropenia is a common limiting factor in dose escalation. In this review, we discuss agents that appear to have potential as bone marrow sparing agents. Computerized catalogs of the National Library of Medicine and Medline were searched for reports on low-molecular-weight compounds that detailed effects on the hematopoietic progenitor cells. The most promising agents are the endogenous peptides p-glutamic acid-glutamic acid-aspartic acid-cysteine-lysine and acetyl-serine-aspartic acid-lysine-proline, and the exogenous compounds amifostine and ammonium trichloro[dioxoethylene-O,O']tellurate, but several others are also discussed. These compounds preserve stem cell function in the presence of antineoplastic drugs of diverse pharmacological classes, and they do so by various mechanisms of action. Their present status in clinical practice is also detailed. More needs to be learned about their mechanisms of action and therapeutic potential, but the results are encouraging for some of these compounds and more clinical trials should be expected.

Serine protease inhibitors expressed in the process of budding of tunicates as revealed by EST analysis.

To identify genes expressed during budding of the tunicate Polyandrocarpa misakiensis, we isolated and sequenced 624 clones from a directionally constructed cDNA library to prepare a catalog of expressed sequence tags (ESTs). A total of 233 ESTs matched genes of known sequence in the SwissProt database. About 24% out of them showed high similarity to ribosomal proteins, twice the value (12%) of pre-budding animals. ESTs involved in the respiratory chain also appeared with significant redundancy, suggesting that tunicate budding is accompanied by the enhancement of energy conversion as well as protein synthesis. Serine protease inhibitor (serpin) afforded another striking example of a gene that was highly expressed in the process of budding. The deduced amino acid sequences of five serpin cDNAs all had two consensus signatures of the Kazal's type of secretory protease inhibitor, one of which had an active site for trypsin and the other for elastase. In line with this, recombinant GST-fusion protein showed both trypsin and elastase inhibitor activities. In accordance with the EST analysis, the hemolymph taken from the budding stage showed the highest activity of trypsin inhibitor. We discuss a possible role that Polyandrocarpa serpins may play in bud development by counteracting trypsin-like serine protease, which could facilitate dedifferentiation of formative tissues.
