Online tables of contents for books: effect on usage.
OBJECTIVES: To explore whether the presence of online tables of contents (TOC) in an online catalog affects circulation (checkouts and inhouse usage). Two major questions were posed: (1) did the presence of online tables of contents for books increase use, and, (2) if it did, what factors might cause the increase? METHOD: A randomized and stratified design was used in tracking usage of 3,957 book titles that were previously divided into two groups: one with TOC and one without TOC. Stratification was done for year of imprint, location, subject, previous use, circulating or non-circulating status, and presence of TOC. The use was tracked by the online catalog statistics in the InnoPac online catalog for fourteen months. RESULTS: The study found that tables of contents do increase usage. It also showed a correlation in the size of the effect based on the currency of the titles. In general, even after adjusting for all of the variables (publication date, location, circulation status, subject, and previous use), the odds of a title being used increased by 45% if the titles had online tables of contents, a statistically significant impact at the 0.05 level. CONCLUSIONS: This case-control study presents new information about the impact on circulation and inhouse use when tables of contents for books are added to the online catalog record. The study helps to establish the positive role of tables of contents in online catalogs. The research establishes TOC as a major parameter that can be successfully studied using quantitative methods. The study also provides information professionals with some guidance on when enhancement of TOC is likely to be most effective in increasing the use of existing collections.
Applications of Raman spectroscopy to library heritage.
This work reports some different applications of Raman spectroscopy, a high sensitive non-destructive technique, to the conservation of Library Heritage. By Raman spectroscopy we were able to detect the chemical mechanisms leading to cellulose degradation, identifying the different functional groups formed during the paper ageing. This kind of information is fundamental to choose a suited restoration treatment. A second reported application is the identification of pigments used to decorate paper and parchments. We report some results obtained from analysis of a XV and a XIII century illuminations.

Medical serials control systems by computer--a state of the art review.
A review of the problems encountered in serials control systems is followed by a description of some of the present-day attempts to solve these problems. Specific networks are described, notably PHILSOM (developed at Washington University School of Medicine Library), the UCLA Biomedical Library's system, and OCLC in Columbus, Ohio. Finally, the role of minicomputers in present and future developments is discussed, and some cautious guesses are made on future directions in the field.
Evolution of a processing system in a large biomedical library.
The processing system used in the UCLA Biomedical Library is modest in size and still under development. Its origins date back to a batch mode serials control system begun in the mid-1960s. This was converted to an on-line system which currently has modules for check-in, updating and retrieval, claims, bindery preparation, and invoice information. Titles can be retrieved at the terminal by search of any word in the title, by subject heading, language, country of publication, and type of publication. The system is adaptable to network use and at present is shared with one other library. To the serials system has been added a computer-assisted cataloging and card production system. The latter utilizes serials nucleus software as well as design for data input and data storage. In-house listings and coding procedures overlap in a general way. Work is under way on further integration of the two processing subsystems and a feasibility study has been completed for addition of a subsystem for acquisitions which will combine and adapt features of the other two; for example, information retrieval characteristics from both, catalog coding and programs for acceptance of data, serials programs for claims, and other output programs. Cost benefits of the subsystems are described and discussed.
Conversion of the periodical collection in a teaching hospital library to microfilm format.
The Martland Hospital Library converted many of its periodical backfiles to 16 mm microfilm cartridges. Some details of program implementation, user reactions, costs, and problems are discussed. In a teaching hospital library microfilm in cartridge format has been well accepted by patrons, in part because the need to read from a projection screen has been minimized by granting liberal printing privileges.
The PHILSOM system--one user's experience.
The University of Texas Health Science Center at San Antonio joined the PHILSOM system, a comprehensive serials control network, in 1971. The experiences of the library in using the system are described. The major benefit of the system has been multiple copies of the holdings list which have made the serial records publicly accessible and significantly increased their value. Tallies of these lists' use indicate that more than half of serials-related questions are now answered directly by the users. The effects of PHILSOM on the procedures of the serials department--processing, claiming, bindery, and personnel are described. Costs to the network and the UTHSCSA Library are briefly summarized.

Bibliographic control of audiovisuals: analysis of a cataloging project using OCLC.
The staff of the Quillen-Dishner College of Medicine Library cataloged 702 audiovisual titles between July 1, 1982, and June 30, 1983, using the OCLC database. This paper discusses the library's audiovisual collection and describes the method and scope of a study conducted during this project, the cataloging standards and conventions adopted, the assignment and use of NLM classification, the provision of summaries for programs, and the amount of staff time expended in cataloging typical items. An analysis of the use of OCLC for this project resulted in the following findings: the rate of successful searches for audiovisual copy was 82.4%; the error rate for records used was 41.9%; modifications were required in every record used; the Library of Congress and seven member institutions provided 62.8% of the records used. It was concluded that the effort to establish bibliographic control of audiovisuals is not widespread and that expanded and improved audiovisual cataloging by the Library of Congress and the National Library of Medicine would substantially contribute to that goal.

Research databases: a new direction in collection development.
A need for centralized access to biomedical databanks was identified at the Medical University of South Carolina. The library has taken a leadership role in administering selection, acquisition, storage, and dissemination of access to these databases. A discussion of established policies and procedures is included. The appendix describes the biomedical databanks and search software selected.
Accessing the biomedical literature: the South Dakota Med-Fax Network.
Librarians developed a plan for a medical information network based upon the needs of South Dakota physicians as revealed in a 1984 survey. The South Dakota Med-Fax Network received private funding in 1987 and became operational in 1988. The Network incorporates interactive simultaneous remote on-line database searching (ISRS) and telefacsimile transmission to expedite the identification and delivery of medical literature to South Dakota physicians. At present, the Network is composed of sixteen institutional sites. Individual physicians may establish their own sites if they provide an IBM compatible personal computer with a modem and purchase a telecommunications software package. The Network will provide training and follow-up support. Use patterns to date demonstrate that telefacsimile transmission is instrumental in reducing significantly the time necessary to deliver journal literature and that ISRS searching is the method of choice in the Network's remote sites.

Developing a preservation policy and procedure statement for a health sciences library.
The preconditions for creating a preservation policy document in a health sciences library are an existing preservation policy for the institution of which it is a part and administrative support for preservation. The assumption underlying preservation activity, from the formulation of general guidelines to the detail of operating procedure, is that collection development and preservation are complementary functions. Documentation of operational procedures in some detail should be a part of the statement. Since preservation activity cuts across functional library structures, all management staff should be involved in the planning process and be made aware of their responsibilities. The creation of a preservation policy statement will highlight unaddressed issues, procedural inadequacies, and differences in staff perceptions of priorities, but a written statement provides a framework for setting priorities and making decisions.
