    The weakening relationship between the Impact Factor and papers’ citations in the digital age :

    « Historically, papers have been physically bound to the journal in which they were published but in the electronic age papers are available individually, no longer tied to their respective journals. Hence, papers now can be read and cited based on their own merits, independently of the journal’s physical availability, reputation, or Impact Factor. We compare the strength of the relationship between journals’ Impact Factors and the actual citations received by their respective papers from 1902 to 2009. Throughout most of the 20th century, papers’ citation rates were increasingly linked to their respective journals’ Impact Factors. However, since 1990, the advent of the digital age, the strength of the relation between Impact Factors and paper citations has been decreasing. This decrease began sooner in physics, a field that was quicker to make the transition into the electronic domain. Furthermore, since 1990, the proportion of highly cited papers coming from highly cited journals has been decreasing, and accordingly, the proportion of highly cited papers not coming from highly cited journals has also been increasing. Should this pattern continue, it might bring an end to the use of the Impact Factor as a way to evaluate the quality of journals, papers and researchers. »

    Leaving Elsevier’s « big deal »: an evaluation of the Italian National Institute of Health experience inside the Bibliosan Consortium :

    « In 2011 the Istituto Superiore di Sanità (ISS), the Italian National Institute of Health, has been forced, due to economic reason, to leave the Bibliosan Consortium contract with the publisher Elsevier. The contract, following the “big deal” model, provided for the maintenance of paper subscriptions and the payment of an additional fee for the whole electronic collection (more than 2,000 journal titles). The continuous increase of annual costs has led to unsustainable growth in costs and to the subsequent cancellation of the contract. This meant that more than 500 researchers of the Institute have suddenly had access to just 180 Elsevier current titles instead of the previous 2,000. The study traces the various stages which led to taking this unavoidable decision to cut about half of the Elsevier’s journals and analyzes its impact. »

    Beyond citations: Scholars’ visibility on the social Web :

    « Traditionally, scholarly impact and visibility have been measured by counting publications and citations in the scholarly literature. However, increasingly scholars are also visible on the Web, establishing presences in a growing variety of social ecosystems. But how wide and established is this presence, and how do measures of social Web impact relate to their more traditional counterparts? To answer this, we sampled 57 presenters from the 2010 Leiden STI Conference, gathering publication and citations counts as well as data from the presenters’ Web « footprints. » We found Web presence widespread and diverse: 84% of scholars had homepages, 70% were on LinkedIn, 23% had public Google Scholar profiles, and 16% were on Twitter. For sampled scholars’ publications, social reference manager bookmarks were compared to Scopus and Web of Science citations; we found that Mendeley covers more than 80% of sampled articles, and that Mendeley bookmarks are significantly correlated (r=.45) to Scopus citation counts. »

    Establishment of Institutional Mechanism for Building National Repository in Health Sciences :

    « National consolidation of published and unpublished literature in the field of biomedical sciences can playa major role in scholarly communication to help the end users in providing research published in the country.Institutional repositories are a good approach for a cost-effective publishing with a cooperation and participationof each institution for capturing, preserving, managing, and nurturing the discussion. In turn, metadata can be harvested centrally to access the digital information of common interest whereas individual libraries shouldable to preserve digital assets. Institutionalisation mode has been recommended for building national digitalrepository system for the country. The public funding should be provided to apex body so as to formulatethe requisite policies for the spread of open access movement in the country and also formulate a long termsustainable model for building national level system in the country. »

    Open Access to Scientific Information: A Review of Initiatives :

    « Open access journals are the one’s which are available online to the reader without financial, legal, ortechnical barriers other than those inseparable from gaining access to the internet. Some of the scholarlyjournals are subsidised, and some require payment. However, a number of challenges remain, such as highand rising subscription prices to scientific publications, an ever-growing volume of scientific data, and theneed to select, curate, and preserve research outputs. Open access benefits researchers, innovators, teachers,students, media professionals, and the general public. It promotes global knowledge flow for the benefit ofscientific discovery, innovation, and socio-economic development. »

    India’s Efforts in Open Access Publishing :

    « For a long time, India has been generating a great deal of scholarly resources in all disciplines. After independence, there was a lot of investment in science and technology, and S&T were used to leverage development efforts and to improve the standard of living. However, one in four Indians still lives below the poverty line. There is a considerable research effort in a wide variety of areas including science, technology, medicine, humanities and social sciences. Research is performed essentially in three sectors: (1) higher educational institutions, such as universities and deemed universities (2) laboratories under different government agencies such as the Council of Scientific and Industrial Research (CSIR), Department of Atomic Energy (DAE), Indian Space Research Organization (ISRO), Defence Research and Development Organization (DRDO), Indian Council of Agricultural Research (ICAR), and Indian Council of Medical Research (ICMR), and (3) laboratories in the industrial sector, both public and private.

    With difficulties such as lack of funds and infrastructure for good quality research, a very common problem for Indian scientists is access and visibility. The accelerating cost of subscriptions to academic serials has created a serials crisis in almost all libraries around the world, including India. Most Indian libraries cannot afford to subscribe to key journals needed by their users/scientists. As a result, it becomes difficult for researchers to have current knowledge. After spending so much effort on research and getting it published in journals, small or big, from around the world, their work is often not noticed by others elsewhere, even within India, working in the same and related areas. No wonder Indian work is poorly cited due to low visibility or circulation of such journals where their works have been published.

    To overcome both these handicaps, one possible solution may be the publishing through Open Access (OA). Open-access publishing is the provision of free online access to quality scholarly material that is available on « open domain, » and not having any restriction of copyright. Although the open access movement began before the advent of the Web, it became more widespread with the adoption of Web access in scholarly activities. The movement spread to all disciplines. There are many different models of open access publishing, for example sponsored OA, OA supported by author fees, and embargoed OA. The intention of all such models is to provide access to scholarly contents to clients. It is, however, assumed as one of the useful media to share research and getting wide visibility from around the world. Some countries like the UK and the US have made better progress, whereas many other countries are lagging behind. The primary goal of this study is to discover the present status of Indian open access ventures and help librarians to understand the opportunities in OA scholarly resources in India. »

    Digital Librarians and the Challenges of Open Access to Knowledge: The Michael Okpara University of Agriculture (MOUAU) Library Experience :

    « The development of Internet technology has provided academic and research institutions with a very high level of visibility on the web. As a result, teaching, learning and research is widely improved in the global society today. The intellectual call for knowledge and information dissemination by countless organizations and educational meetings has given birth to a terminology called open access. This initiative is aimed at bringing the knowledge society to a state of free access to all kinds of information and learning material using the Internet and ICT tools. The library plays an important role in sustaining the open access initiative (Das, 2008). Librarians who ensure the organization and dissemination of full-text content of knowledge materials to online communities are the digital librarians. »

    The Anatomy of a Data Citation: Discovery, Reuse, and Credit :

    « INTRODUCTION : Data citation should be a necessary corollary of data publication and reuse. Many researchers are reluctant to share their data, yet they are increasingly encouraged to do just that. Reward structures must be in place to encourage data publication, and citation is the appropriate tool for scholarly acknowledgment. Data citation also allows for the identification, retrieval, replication, and verification of data underlying published studies.

    METHODS : This study examines author behavior and sources of instruction in disciplinary and cultural norms for writing style and citation via a content analysis of journal articles, author instructions, style manuals, and data publishers. Instances of data citation are benchmarked against a Data Citation Adequacy Index.

    RESULTS : Roughly half of journals point toward a style manual that addresses data citation, but the majority of journal articles failed to include an adequate citation to data used in secondary analysis studies. DISCUSSION Full citation of data is not currently a normative behavior in scholarly writing. Multiplicity of data types and lack of awareness regarding existing standards contribute to the problem.

    CONCLUSION : Citations for data must be promoted as an essential component of data publication, sharing, and reuse. Despite confounding factors, librarians and information professionals are well-positioned and should persist in advancing data citation as a normative practice across domains. Doing so promotes a value proposition for data sharing and secondary research broadly, thereby accelerating the pace of scientific research. »

    The Accessibility Quotient: A New Measure of Open Access :

    « INTRODUCTION: The Accessibility Quotient (AQ), a new measure for assisting authors and librarians in assessing and characterizing the degree of accessibility for a group of papers, is proposed and described. The AQ offers a concise measure that assesses the accessibility of peer-reviewed research produced by an individual or group, by incorporating data on open availability to readers worldwide, the degree of financial barrier to access, and journal quality. The paper reports on the context for developing this measure, how the AQ is calculated, how it can be used in faculty outreach, and why it is a useful lens to use in assessing progress towards more open access to research.

    METHODS: Journal articles published in 2009 and 2010 by faculty members from one department in each of MIT’s five schools were examined. The AQ was calculated using economist Ted Bergstrom’s Relative Price Index to assess affordability and quality, and data from SHERPA/RoMEO to assess the right to share the peer-reviewed version of an article.

    RESULTS: The results show that 2009 and 2010 publications by the Media Lab and Physics have the potential to be more open than those of Sloan (Management), Mechanical Engineering, and Linguistics & Philosophy.

    DISCUSSION: Appropriate interpretation and applications of the AQ are discussed and some limitations of the measure are examined, with suggestions for future studies which may improve the accuracy and relevance of the AQ.

    CONCLUSION: The AQ offers a concise assessment of accessibility for authors, departments, disciplines, or universities who wish to characterize or understand the degree of access to their research output, capturing additional dimensions of accessibility that matter to faculty. »
