Assessing grey literature use by researchers of Council for Scientific and Industrial Research (CSIR), India

The present study on the use of both external and internal grey literature by CSIR researchers shows that technical reports are most used followed by doctoral theses. It was found that engineering and physical sciences laboratories use more internal grey literature than chemical and biological sciences laboratories. These and other findings help is framing content development policy for technical grey literature, framing policies for internal grey literature archiving, designing digital repository framework to archive internally generated grey literature and improve access and devise ways to enhance their visibility and use

Discovery of the Acoustic Faraday Effect in Superfluid 3He-B

We report the discovery of the acoustic Faraday effect in superfluid 3He-B. The observation of this effect provides the first direct evidence for propagating transverse acoustic waves in liquid 3He, a mode first predicted by Landau in 1957. The Faraday rotation is large and observable because of spontaneously broken spin-orbit symmetry in 3He-B. We compare the experimental observations with a simulation of the transverse acoustic impedance that includes the field-induced circular birefringence of transverse waves.Comment: 4 pages in RevTex plus 3 postscript figures; new version includes: minor corrections to the text and an updated of list of reference

Open source software based information services at CSIR-NAL

R&D library and information centers play important role in fulfilling information needs of its scientists and technologists. With the advent of ICT, roles and services of Information centers and information seeking behaviors among its patrons shifted dramatically towards e- environment. Cost of the software tools available to implement web based information services is not affordable for libraries and information centers in developing countries. Best possible solution for this problem will be adopting open source based software tools in libraries. This paper highlights various electronic information services implemented using open source software at CSIR-NAL

Grey literature archiving pattern in open access (OA) repositories with special emphasis on Indian OA repositories

Purpose: This paper aims to examine the grey literature archiving pattern at open-access repositories with special reference to Indian open-access repositories. Design/methodology/approach: The Bielefeld Academic Search Engine (BASE) was used to collect data from different document types archived by open-access repositories across the world. Data were collected by advanced search and browse features available at the BASE on document types, the number of repositories by country wise and Indian academic and research repositories. Data were tabulated using MS Excel for further analysis. Findings: Findings indicated that open-access repositories across the world are primarily archiving reviewed literature. Grey literature is archived more at European and North American repositories compared to rest of the world. Reports, theses, dissertations and data sets are the major grey document types archived. In India, a significant contributor to the BASE index with 146 open-access sources, reviewed literature is the largest archived document types, and grey literature is above world average due to the presence of theses and dissertations at repositories of academic institutions. Originality/value: Grey literature is considered as valuable sources of information for research and development. The study enables to get insights about the amount of grey content archived at open-access repositories. These findings can further be used to investigate the reasons/technology limitations for the lesser volume of grey content in repositories. Furthermore, this study helps to better understand the grey literature archiving pattern and need for corrective measures based on the success stories of repositories of Europe and North America

Building Indian Language Digital Library Collections: Some Experiences with Greenstone Software

With its diverse cultural and linguistic heritage, India today produces significant volume of digital material in Indian languages. This has been facilitated by increasing availability of word processing systems supporting Indian languages and their use in various areas including e-governance; education and research; and mass media. There is need for digital library software for organizing and provision of access to this material. Such software has to meet two prime requirements: Indexing and searching of documents in Indian languages (full text and metadata), and customizing the collection user interface in Indian languages. Further the software should be able to handle Indian language material in different encoding formats and fonts. Majority of Indian language material available online today seem to follow one of the three encoding strategies: ISO 8859-1 and Windows 1252 series character sets, with custom fonts; ad-hoc (font-specific or user defined) encoding schemes; and Unicode character set. Search and retrieval requirements would include features such as word truncation and alphabetical sorting. Cross-language material searching is an advanced search requirement. Greenstone is a very popular open source software used today for creating digital library collections. Main objective of this study was to assess capabilities of this software in creating Indian language digital library collections with above mentioned requirements for indexing, searching and display. We gathered five sample collections in two Indian languages Hindi and Kannada, in different encoding formats, for this study. For each of these collections, we assessed the multilingual support of Greenstone with respect to collection building; search and retrieval; and interface design. We used the Collector approach of Greenstone to build the five collections. We could successfully build the collections. Limitations were found in handling metadata in Indian languages using the GLI approach. We present details of internal mapping of character sets carried out by Greenstone during collection building process. We could successfully carry out simple keyword and Boolean searches on these collections. We discuss details of search features. Viewing results requires installation of suitable fonts at the operating system level and configuration of the browser. We found limitations in sorting. Greenstone does not support crosslanguage searching. In terms of users interface, Greenstone has in-built support for customizing the interface for well known languages. It also supports designing customized interface for other languages. We could successfully design desired user interface for the test collections in Hindi and Kannada. Overall, Greenstone appears to be a versatile software for building Indian language digital library collections, with some limitations

A study of research publications of top NIRF ranked engineering institutions in Karnataka

The study evaluates the research performance of top-six NIRF ranked engineering institutions in Karnataka. The study uses scientometrics indicators like publication and citation growth, AGR, RGR, DT, citation productivity of open access publications, and document types. The analysis revealed that publication productivity increased after the introduction of NIRF in 2016. The average citations of all the institutions increased, and MS Ramaiah Institute of Technology (MSRIT) recorded the highest 1.7 citations per paper, followed by Visvesvaraya Technological University (VTU) with 1.69 citations per paper. The decreasing trend of relative growth and increased doubling time reveal that the institutes are reaching their saturation point in their publication productivity. The open-access articles' average citations are higher than non-OA articles. The Rashtreeya Vidyalaya College of Engineering (RVCE) open access articles received the highest citations, 11.8 average citations—nearly four times higher than closed access articles, with 2.58 average citations
