- Abstract
- This article focuses on the process of scientific and scholarly communication. Data on open access publications on the Internet not only provides a supplement to the traditional citation indexes but also enables analysis of the microprocesses and daily practices that constitute scientific communication. This article focuses on a stage in the life cycle of scientific and scholarly information that precedes the publication of formal research articles in the scientific and scholarly literature. Binomial logistic regression models are used to analyse precise mechanisms at work in the transformation of a working paper (WP) into a journal article (JA) in the field of economics. The study unveils a fine-grained process of adapting WPs to their new context as JAs by deleting and adding literature references, which perhaps can be best captured by the term sculpting.

- Abstract
- A review of recent developments in electronic publishing, with a focus on Open Access (OA) is provided. It describes the two main types of OA, i.e. the `gold' OA journal route and the 'green' repository route, highlighting the advantages and disadvantages of the two, and the reactions of the publishing industry to these developments. Quality, cost and copyright issues are explored, as well as some of the business models of OA. It is noted that whilst so far there is no evidence that a shift to OA will lead to libraries cancelling subscriptions to toll-access journals, this may happen in the future, and that despite the apparently compelling reasons for authors to move to OA, so far few have shown themselves willing to do so. Conclusions about the future of scholarly publications are drawn.

- Abstract
- This volume is the first book coherently summarizing the current issues in digital libraries research, design and management. It presents, in a homogeneous way, thoroughly revised versions of 15 papers accepted for the First International Workshop on Digital Libraries, DL '94, held at Rutgers University in May 1994; in addition there are two introductory chapters provided by the volume editors, as well as a comprehensive bibliography listing 262 entries. Besides introductory aspects, the topics addressed are administration and management, information retrieval and hypertext, classification and indexing, and prototypes and applications. The volume is intended for researchers and design professionals in the field, as well as for experts from libraries administration and scientific publishing.

- Abstract
- Zentrale Erwerbung von wissenschaftlichen Informationsressourcen im Netz der virtuellen Hybridbibliothek der Max-Planck-Gesellschaft »Excellent Information Services for Excellent Research« ist das Motto der Anfang 2007 gegründeten Max Planck Digital Library (MPDL). Diese ambitionierte Leitlinie würdigt die Relevanz eines modernen wissenschaftlichen Informationsmanagements für eine exzellente Spitzenforschung. Mit Gründung der MPDL wurde in der Max-Planck-Gesellschaft (MPG) ein entscheidender Schritt zur zentralen Unterstützung eines bisher weitgehend dezentralen Informationsversorgungsnetzes gegangen. Die Entscheidung zu einer Kombination aus zentraler und dezentraler Informationsversorgung trägt den Veränderungen Rechnung, die sich durch die Möglichkeiten der digitalen Welt ergeben haben. Intention der Neugründung ist jedoch nicht, ein unter der Prämisse der Institutsautonomie etabliertes, wohl durchdachtes Literatur- und Informationsversorgungssystem sukzessive durch eine zentrale Einheit abzulösen, sondern gemäß der Maxime der Subsidiarität Stärken von dezentralen und von zentralen Einheiten zu einem effizienten Gesamtsystem zu ergänzen. Der vorliegende Artikel skizziert das Netz der Informationsversorgung in der MPG mit dem Schwerpunkt auf der Versorgung mit elektronischen Medien des institutsübergreifenden Bedarfs. Dieser Schwerpunkt kennzeichnet eines der Hauptarbeitsfelder der MPDL, deren weitere Services und Arbeitsfelder kontextgebunden und ausgewählt vorgestellt werden sollen?

- Abstract
- A statistical analysis of full text downloads of articles in Elsevier's ScienceDirect covering all disciplines reveals large differences in download frequencies, their skewness, and their correlation with Scopus-based citation counts, between disciplines, journals, and document types. Download counts tend to be 2 orders of magnitude higher and less skewedly distributed than citations. A mathematical model based on the sum of two exponentials does not adequately capture monthly download counts. The degree of correlation at the article level within a journal is similar to that at the journal level in the discipline covered by that journal, suggesting that the differences between journals are, to a large extent, discipline specific. Despite the fact that in all studied journals download and citation counts per article positively correlate, little overlap may exist between the set of articles appearing in the top of the citation distribution and that with the most frequently downloaded ones. Usage and citation leaks, bulk downloading, differences between reader and author populations in a subject field, the type of document or its content, differences in obsolescence patterns between downloads and citations, and different functions of reading and citing in the research process all provide possible explanations of differences between download and citation distributions.

- Abstract
- We investigate the extent to which open-access (OA) journals and articles in biology, computer science, economics, history, medicine, and psychology are indexed in each of 11 bibliographic databases. We also look for variations in index coverage by journal subject, journal size, publisher type, publisher size, date of first OA issue, region of publication, language of publication, publication fee, and citation impact factor. Two databases, Biological Abstracts and PubMed, provide very good coverage of the OA journal literature, indexing 60 to 63% of all OA articles in their disciplines. Five databases provide moderately good coverage (22-41%), and four provide relatively poor coverage (0-12%). OA articles in biology journals, English-only journals, high-impact journals, and journals that charge publication fees of $1,000 or more are especially likely to be indexed. Conversely, articles from OA publishers in Africa, Asia, or Central/South America are especially unlikely to be indexed. Four of the 11 databases index commercially published articles at a substantially higher rate than articles published by universities, scholarly societies, nonprofit publishers, or governments. Finally, three databases-EBSCO Academic Search Complete, ProQuest Research Library, and Wilson OmniFile-provide less comprehensive coverage of OA articles than of articles in comparable subscription journals.

- Abstract
- Purpose The four major Subject Repositories (SRs), arXiv, Research Papers in Economics (RePEc), Social Science Research Network (SSRN) and PubMed Central (PMC), are all important within their disciplines but no previous study has systematically compared how often they are cited in academic publications. In response, the purpose of this paper is to report an analysis of citations to SRs from Scopus publications, 2000-2013. Design/methodology/approach Scopus searches were used to count the number of documents citing the four SRs in each year. A random sample of 384 documents citing the four SRs was then visited to investigate the nature of the citations. Findings Each SR was most cited within its own subject area but attracted substantial citations from other subject areas, suggesting that they are open to interdisciplinary uses. The proportion of documents citing each SR is continuing to increase rapidly, and the SRs all seem to attract substantial numbers of citations from more than one discipline. Research limitations/implications Scopus does not cover all publications, and most citations to documents found in the four SRs presumably cite the published version, when one exists, rather than the repository version. Practical implications SRs are continuing to grow and do not seem to be threatened by institutional repositories and so research managers should encourage their continued use within their core disciplines, including for research that aims at an audience in other disciplines. Originality/value This is the first simultaneous analysis of Scopus citations to the four most popular SRs.

- Abstract
- Purpose The purpose of this paper is to analyze the relationship between dissemination of research papers on Twitter and its influence on research impact. Design/methodology/approach Four types of journal Twitter accounts (journal, owner, publisher and no Twitter account) were defined to observe differences in the number of tweets and citations. In total, 4,176 articles from 350 journals were extracted from Plum Analytics. This altmetric provider tracks the number of tweets and citations for each paper. Student's t-test for two-paired samples was used to detect significant differences between each group of journals. Regression analysis was performed to detect which variables may influence the getting of tweets and citations. Findings The results show that journals with their own Twitter account obtain more tweets (46 percent) and citations (34 percent) than journals without a Twitter account. Followers is the variable that attracts more tweets (ß=0.47) and citations (ß=0.28) but the effect is small and the fit is not good for tweets (R2=0.46) and insignificant for citations (R2=0.18). Originality/value This is the first study that tests the performance of research journals on Twitter according to their handles, observing how the dissemination of content in this microblogging network influences the citation of their papers.

- Abstract
- The debate about access to scientific research raises questions about the current effectiveness of scholarly communication processes. This book explores, from an independent point of view, the current state of the STM publishing market, new publishing technologies and business models as well as the information habit of researchers, the politics of research funders, and the demand for scientific research as a public good. The book also investigates the democratisation of science including how the information needs of knowledge workers outside academia can be embraced in future.
