This issue of Library Hi Tech contains a series of articles about the TULIP materials science journal access project, an unprecedented cooperative undertaking involving Elsevier Science Publishing and a number of major universities in the United States.

This article elaborates on the technical aspects of the TULIP project as it is developed and implemented at Elsevier Science to produce journal material in electronic formats and deliver this material to the collaborating universities. Other articles in this issue describe the different systems at those universities.

Outlines new database products appearing in the Gale Directory of Databases, a two‐volume work published twice a year. Provides figures for the distribution and percentage of new and newly implemented science, technology and medicine databases including name, vendor and medium. Briefly discusses these by each medium.

This paper aims to examine demand-driven acquisition (DDA) models that require an initial or minimum investment through the University of Wyoming’s experience with Elsevier’s Evidence-Based Selection model.

In an attempt to avoid title-by-title selection and a desire to explore an alternative to all or nothing e-book packages, the University of Wyoming Libraries (UWL) participated in Elsevier’s Evidence-Based Selection purchase model for 2011 and 2012 e-book content in the 2013 calendar year. After an initial investment, the library was given access to the content. At the end of one year, UWL was provided with use data for the content and could choose an amount of content to retain up to Elsevier’s established “access fee”.

Many studies have shown that print monographs in academic libraries do not circulate in high volumes. The use data for the titles included in the Evidence-Based Selection model was congruous with studies of print monograph circulation. Through a review of the literature and an account of the UWL’ experience with Elsevier’s Evidence-Based Selection model, this paper advocates for libraries to exercise caution when considering a DDA model requiring an initial investment.

DDA is a purchase model that is becoming immensely popular, and in some libraries, the primary mode of acquisition. The value of this paper lies in the examination of a DDA model of a major academic publisher and the account of one library’s experience with that model.

The purpose of this paper is to explore whether the databases from a certain library are Pareto-compliant or not? If so, to what extent is the Pareto principle performance evident among these databases? The other purpose is to determine the differences in Pareto principle performance according to time change and database type.

Data on full-text downloads from six e-resources – Elsevier ScienceDirect (SD), Wiley Blackwell, Springer Journal, EBSCO Business Source Premier (BSP), American Chemical Society and American Institute of Physics (AIP) – for the period 2007-2013 were analysed; 42 samples were collected from these databases. The proportion of frequently downloaded journals from databases was selected as an indicator to determine differences in Pareto principle performance according to time change. The difference between the proportion of frequently downloaded journals and the classic proportion of 20 per cent was used as indicator to determine difference in Pareto principle performance related to database type.

There are 33 samples (78.57 per cent) which exhibited the Pareto principle. Four databases – Elsevier SD, Wiley Blackwell, EBSCO BSP and AIP – constantly exhibited the Pareto principle. The differences were not significant according to time change. The two multi-discipline databases – Elsevier SD and Wiley Blackwell – fluctuated more moderately than the two single-discipline databases – EBSCO BSP and AIP. Multi-discipline and single-discipline databases showed some differences in Pareto principle performance; however, these differences were not remarkable.

The Pareto principle confirmed that there were frequent and infrequent downloads of e-journals from e-journal databases. It was of great importance to analyse these to improve digital resources acquisition and user service.

This article reviews Scirus, Elsevier Science’s search engine. Scirus is advertised as the world’s first scientific search engine. It indexes freely‐available Web sites, as well as proprietary content owned by Elsevier and its partners. Scirus was awarded “best specialty search engine” by Search Engine Watch, and may spark a trend whereby other content providers index their content with discipline‐specific Web sites.

Presents a review on implementing finite element methods on supercomputers, workstations and PCs and gives main trends in hardware and software developments. An appendix included at the end of the paper presents a bibliography on the subjects retrospectively to 1985 and approximately 1,100 references are listed.

Citation is an important measure of quality, and it plays a vital role in evaluating scientific research. However, citation advantage varies from discipline to discipline, subject to subject and topic to topic. This study aims to compare the citation advantage of open access and toll access articles from four subfields of computer science.

This research studies the articles published by two prestigious publishers: Springer and Elsevier in the author-pays charges model from 2011 to 2015. For experimentation, four sub-domains of computer science are selected including (a) artificial intelligence, (b) human–computer interaction, (c) computer vision and graphics, and (d) software engineering. The open-access and toll-based citation advantage is studied and analyzed at the micro level within the computer science domain by performing independent sample t-tests.

The results of the study highlight that open access articles have a higher citation advantage as compared to toll access articles across years and sub-domains. Further, an increase in open access articles has been observed from 2011 to 2015. The findings of the study show that the citation advantage of open access articles varies among different sub-domains of a subject. The study contributed to the body of knowledge by validating the positive movement toward open access articles in the field of computer science and its sub-domains. Further, this work added the success of the author-pays charges model in terms of citation advantage to the literature of open access.

To the best of the authors’ knowledge, this is the first study to examine the citation advantage of the author-pays charges model at a subject level (computer science) along with four sub-domains of computer science.

In recent years, a growing number of libraries have canceled or unbundled their “Big Deal” journal subscriptions – those subscriptions that include a full package of digital journal titles for one discounted cost. This started as an affordability problem but has slowly morphed into a challenge from libraries demanding a new pricing structure that accommodates and spurs the growing open access movement.

The change has caused a variety of challenges for technical services units including the increased need for user data, increasingly complicated workflows as they manage partial subscriptions, new interactions with consortia, and ongoing campus conversations. Whether the library is seeking to simply unbundle due to budget constraints, or push for new models such as “read and publish”, there is a tremendous impact on the work of technical services units.

This chapter will explore the rationale and growth of the Big Deal, how it is breaking, four case studies on breaking Big Deals, a brief discussion of new transformative agreements, new challenges for consortia, and implications for technical services units moving forward.

Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.
