The Implications For Publishing Of Electronic Document Storage And Delivery, Maurice B. Line

Proceedings of the IATUL Conferences

The electronic storage and delivery of serial articles will affect not only libraries and their users but publishers, whose main market is libraries. In particular, the ability of libraries to acquire individual articles rather than whole serials could destroy the viability of conventional published serials and result in the use of market rather than quality criteria in deciding which articles to accept for 'publication': the system would become user-driven rather than author-driven. The large investment required for electronic publishing might lead to the take-over of traditional publishers by large corporations whose interests were purely commercial. Data-bases handling the electronic texts …

The Changing Role Of Secondary Information Services, Stella Keenan

Proceedings of the IATUL Conferences

Secondary serial publications (abstracting and indexing services) are, by their nature, closely linked to the primary journal literature. They are affected by the publication pattern and processes of the primary serials, and developments in technology and communication facilities. In the 1960s and 1970s it was generally agreed that secondary services could be divided into disciplines oriented services and mission or project oriented services. This long established division is currently changing as secondary services have become increasingly flexible and more concerned than ever with user requirements.

Technological developments and the continuing economic constraints are exerting pressure on the abstracting and indexing …

Selective Article Delivery, G. A. Somerfield

Proceedings of the IATUL Conferences

Online searching of databases is rapidly changing traditional methods of information retrieval by making it easier to identify relevant single articles. The databases cover a wider range of journals than is of ten available in the local library, which is simultaneously tending to reduce its coverage in response to severe budget pressures. Consequently, many single documents are provided as photocopies through the network of major lending libraries since few publishers supply single articles other than reprints at the time the journal is published.

Virtually all of this document delivery relies heavily upon physical transport of a document from one place …

Periodicals Collections In Academic Libraries Of The Federal Republic Of Germany: Development And Managerial Aspects, Richard Landwehrmeyer

Proceedings of the IATUL Conferences

Academic libraries in the Federal Republic of Germany had, after World War II, to devote their main activities on collection development with emphasis on periodical collections. Circumstances recommended decentralized cooperative acquisition programmes coordinated and supported by the Deutsche Forschungsgemeinschaft. Besides these decentralized special collections, local serials collections developed in number and coverage to a fair standard: the traditional universities were enlarged, former Technische Hochschulen expanded to full universities, new universities were founded. Both local and regional/supra-regional activities led up to acceptable satisfaction rates. These were positively influenced by the creation of periodical holding lists (local, regional, national) , culminating in …

Open Access Use Of Serials Collections, Arja-Riitta Haarala

Proceedings of the IATUL Conferences

The paper reviews briefly use studies concerned with periodicals and serials collections from the point of view of methodology. A "bundling" method for the measurement of open access use of serials collection is presented . Results of a study carried out in 1979 at Helsinki University of Technology Library are reported. The sample consisted of 1487 titles. 212 titles formed a core group of serials. They cavered 50% of the total use. 50% of the sample cavered 90% of the usage. Language and subject distributions for serials not used and for the core group are also given. The care group …

Serials And "Grey Literature", Dieter Schmidmaier

Proceedings of the IATUL Conferences

"Grey literature" is literature which is not directly accessible. Its procurement, exploitation, storage and incorporation in information systems can only be carried out under complicated conditions.

Journals in the sense of "Grey literature" are:

1. (Scientific) journals published by universities, academies and research institutes, as well as periodic publications about the results of research issued by firms engaged in such work.
2. Journals and newspapers published by parties, organisations, associations, cooperatives, companies, libraries and museums.
3. Journals which do not contain original scientific contributions, as well as those issued by book clubs and other organisations which publish technical literature and also belles-lettres.

A Model For Storage Of Different Volumes Of A Journal In Electronic Data Processing: The Dortmund Online Library System Dobis, Martin Büren

Proceedings of the IATUL Conferences

The contribution deals with the processing of periodical volumes by the Dortmund Online Library System. As an integrated system DOBIS has to consider the divergent requisitions of circulation and cataloguing. For catalogue output it makes available bibliographically correct descriptions of the entire periodical. For circulation it provides information concerning the single periodical volume and its non-bibliographic data, e.g. status and circulation conditions. The bibliographic description and the affiliated volumes are connected in the data base by sorted references. By this means it is possible to show on the screen a list of the volumes belonging to a periodical in inverse …

The University Library Hannover And Technische Informationsbibliothek As A Library Of Last Resort - Or As A Library Of First Resort. Some Aspects Of The Operation Of The Largest Technical Library In The Federal Republic Of Germany, H. Drubba

Proceedings of the IATUL Conferences

Technische Informationsbibliothek Hannover (TIB) is one of the four central subject libraries in the Federal Republic of Germany. TIB was founded in 1959 and established in Hannover because here a fairly large and comprehensive technical library existed, the present University Library Hannover (UB Hannover).

Both libraries receive among themselves currently about 19.000 serials (among this number many of the Soviet 'Trudy' or 'Sbornik' type series). Not only the literature of technology is collected but also of the basic sciences (mathematics, physics, and chemistry). The serials are collected comprehensively, regardless of language, country of origin, or 'scientific' level, in fact a …

Computer Analysis Of X-Band Radar Data, D. J. Knowlton, R. M. Hoffer

LARS Technical Reports

Dual polarized X-Band Synthetic Aperture Radar (SAR) data were obtained for a test site in South Carolina containing a variety of forest and agricultural cover types, as well as water and urban areas. The optically correlated images were digitized with a scanning microdensitometer using a 40 µm aperture. Digital registration of the two polarizations was more difficult than anticipated due to geometric variations in the imagery. However, a successful registration was obtained, and a "degraded" 30 m resolution data set was generated in addition to the original 15 m resolution data set.

Computer analysis indicated a statistically significant look-angle effect …

Simple Methods For Determining The Accuracy Of Tumor Blood Flow Measurements Using Radioactive Microspheres In Rats, Rosanna C. Chan, Charles F. Babbs, Richard J. Vetter

Weldon School of Biomedical Engineering Faculty Publications

Two simple methods are presented that allow positive identification of the accuracy and precision of the microsphere technique and a quick verification of sphere entrapment in tumor vessels. A known flow of Ringer's solution from a motor-driven syringe is perfused through the rat's isolated systemic circulation from left ventricle to right atrium and collected in a funnel. Using this preparation, total blood flow in rats measured with radioactive microspheres injected into the left ventricle was 97% of actual flow. The coefficient of variation (standard deviation/mean) of the microsphere measurements was 0.22. In the same preparation, non-entrapment of microspheres in subcutaneous …
