Using a journal availability study to improve access.

PURPOSE: Identify journal collection access and use factors. SETTING AND SUBJECTS: University of North Carolina at Chapel Hill's Health Sciences Library patrons. METHODOLOGY: Survey forms and user interactions were monitored once a week for twelve weeks during the fall 1997 semester. The project was based on a 1989 New Mexico State University study and used Kantor's Branching Analysis to measure responses. RESULT: 80% of reported sought journal articles were found successfully. Along with journal usage data, the library obtained demographic and behavioral information. DISCUSSION AND CONCLUSIONS: Journals are the library's most used resource and, even as more electronic journals are offered, print journals continue to make up the majority of the collection. Several factors highlighted the need to study journal availability. User groups indicated that finding journals was problematic, and internal statistics showed people requesting interlibrary loans for owned items. The study looked at success rates, time, and ease of finding journals. A variety of reasons contributed to not finding journals. While overall user reports indicated relatively high success rate and satisfaction, there were problems to be addressed. As the library proceeds in redesigning both the physical space and electronic presence, the collected data have provided valuable direction.

Print versus electronic journals: a preliminary investigation into the effect of journal format on research processes.

PURPOSE: To begin investigating the impact of electronic journals on research processes such as information seeking, the authors conducted a pilot journal-use study to test the hypothesis that patrons use print and electronic journals differently. METHODOLOGY: We placed fifteen high-use print titles also available in electronic format behind the circulation desk; patrons were asked to complete a survey upon requesting a journal. We also conducted a parallel survey of patrons using library computers. Both surveys asked patrons to identify themselves by user category and queried them about their journal use. RESULTS: During the month-long study, patrons completed sixty-nine surveys of electronic and ninety surveys of print journal use. Results analysis indicated that fellows, students, and residents preferred electronic journals, and faculty preferred print journals. Patrons used print journals for reading articles and scanning contents; they employed electronic journals for printing articles and checking references. Users considered electronic journals easier to access and search than print journals; however, they reported that print journals had higher quality text and figures. DISCUSSION/CONCLUSION: This study is an introductory step in examining how electronic journals affect research processes. Our data revealed that there were distinct preferences in format among categories. In addition to collection management implications for libraries, these data also have implications for publishers and educators; current electronic formats do not facilitate all types of uses and thus may be changing learning patterns as well.

Language and country preponderance trends in MEDLINE and its causes.

OBJECTIVE: The authors characterized the output of MEDLINE papers by language and country of publication during a thirty-four-year time period. METHODS: We classified MEDLINE's journal articles by country of publication (Anglos/Non-Anglos) and language (English/Non-English) for the years 1966 and from 1970 to 2000 at five-year intervals. Eight English-speaking countries were considered Anglos. Linear regression analysis of number of papers versus time was performed. RESULTS: The global number of papers increased linearly at a rate of 8,142 papers per year. Anglo and English papers also increased linearly (6,740 and 9,199, respectively). Journals of Non-Anglo countries accounted for 25% of the English language increase (2,438 per year). Only Non-English papers decreased at a rate of 1,056 fewer papers per year. These trends have led to overwhelming shares of English and Anglo papers in MEDLINE. In 2000, 68% of all papers were published in the 8 Anglo countries and 90% were written in English. CONCLUSIONS: The Anglo and English preponderances appear to be a consequence of at least two phenomena: (1) editorial policy changes in MEDLINE and in some journals from Non-Anglo countries and (2) factors affecting Non-Anglo researchers in the third world (publication constraints, migration, and undersupport). These are tentative conclusions that need confirmation.

[The teaching health centers of Barcelona. The opinions of residents].

OBJECTIVE: To examine different aspects of the teaching health centres (THC) in the province of Barcelona as evaluated by the ex-residents (Exc-R) from general practice and community medicine (GP&CM). DESIGN: Descriptive study, gathering information by means of a self-administered postal questionnaire, with an addressed reply envelope. SETTING: Barcelona teaching unit (BTU). PARTICIPANTS: Eighty-one general practitioners whose qualifying years were 1987-89, 1988-90 and 1989-91, and who did their last residents year in the THC of the BTU. MEASUREMENTS AND MAIN RESULTS: There are significant differences (p < 0.05) between the various THC, in terms of: quality of teaching material and library; evaluation of the tutor in terms of attendance of classes and comment on medical histories; and average evaluation of tutor by the Ex-R. CONCLUSIONS: We propose that anonymous evaluations made by residents of their tutors should be generalised and used for, amongst other purposes, maintaining or revoking the accreditations of specific THC or tutors.

Combinatorial libraries of transition-metal complexes, catalysts and materials.

The design, synthesis and evaluation of transition metal containing combinatorial libraries has received much attention in the past few years. As a result, a variety of synthetic techniques have been developed, and rapid assays for metal ion binding have yielded new ligand classes displaying high affinity and selectivity. Research in catalysis has centered around lead optimization using much smaller parallel libraries because of the lack of a truly efficient reaction screening method. Materials science applications have also focused on spatially addressed libraries and have employed a variety of techniques to identify compounds with desired physical properties. Nonetheless, high-throughput characterization and reaction product detection methods must still be developed in order to realize the full potential of combinatorial chemistry for the discovery of novel metal-containing compounds.

Tomorrow's library.

The buildings in which we house libraries are like other special purpose structures; the needs they fill are significantly influenced by technology. A prime function of the library building is to house collections (of people, material, and systems) as well as collections of collections (networks). Electronic formats for library material offer new approaches to information service delivery. An example, the information access station, typifies how traditional functions can be reconfigured with respect to space. Flexible design can help ensure that tomorrow's libraries meet the users' needs, but we need to question all our assumptions about building design including those driven by our understanding of the browsing process.

An improved method for constructing a full-length enriched cDNA library using small amounts of total RNA as a starting material.

We have developed an improved method for constructing a full-length cDNA library using small quantity of material by modifying the original oligo-capping method. In our devised method, total RNAs are used in sequential oligo-capping steps directly without preliminary mRNA purification. Using this method, we constructed full- length cDNA libraries from 100 mg of total RNA. These libraries contained 8x10(5) to 8x10(6) independent clones with average insert sizes of 2.0 kb. Moreover, the number of full-length cDNAs containing the translation initiation codon ATG in the constructed libraries was estimated to 60-70%. In addition, 54% of the known cDNAs had a longer 5' end than the corresponding genes in the public database. Our results show that the method can be effectively used to construct full-length enriched cDNA libraries, especially, if starting material is limited.

The Medical Library Center of New York: a progress report.

An article published in the Bulletin in 1963 outlined the proposed program of the Medical Library Center of New York. This progress report describes actual functions of the Center and attempts to evaluate them after four years of experience. Details of adapting a building intended for other use, financing this cooperative enterprise, applying standard library techniques and equipment to an atypical library, and acquiring materials that complement, rather than duplicate, the collections of member libraries are given. New services, not envisioned in detail in the initial program, but initiated during this period of operation, are mentioned. The report ends with a tentative look into the future.

High-throughput characterisation of materials by photoluminescence spectroscopy.

An automatic system for high-throughput (HT) characterisation of large libraries of solid materials by photoluminescence spectroscopy is described. The system provides time-resolved transient emission spectra in the microsecond scale and can be employed for characterisation of materials of interest in the fields of catalysis and electroluminescence, amongst others. Here, we present its application to the optimisation of the ship-in-a-bottle synthesis of a novel electroluminescent polymer (PPV) and a photocatalyst (TP+), both encapsulated in large-pore zeolites.
