Purpose – The purpose of this paper is to explore various types of research materials in Indian institutional repositories. Design/methodology/approach – The repositories are identified from the Registry of Open Access Repositories (ROAR). The repository sites were visited to collect the data necessary for the study. Findings – The present study reveals that barring a few repositories the collections of most of the repositories are very low. The percentage of archived materials is high for journal papers, and moderate for conference papers/thesis. However it is very low for preprints/working papers, teaching resources and patents. Originality/value – The study provides an overview of archived material in institutional repositories in India.

AbstractPurpose -The purpose of this paper is to evaluate the interoperability of ten open access repositories in the field of computer science and IT. Design/methodology/approach -The repositories are identified from the OpenDOAR directory of OA repositories. Five documents from each repository are searched in ten search engines/data discovery tools (OAIster, Scirus, Google, MSN, Yahoo, All the Web, Ask, Altavista, AOL and Gigablast) for determining the visibility of repositories. The documents from each repository are selected randomly using the function sample ( ) of R software. Findings -None of the repositories in the study are fully interoperable (the visibility of repositories in search engines/data discovery tools range from 4 per cent to 92 per cent). OAI-PMH compliance enhances the visibility of the repositories considerably. Google and MSN retrieved the highest number of documents from the repositories and Gigablast the least. Originality/value -The paper will encourage the repository administrators to improve the visibility of their repositories keeping in view the indexing policies of various search engines to ensure maximum research impact.

The present study attempts to ascertain the proportion of missing web references of 5-10-year-old research papers of the five leading open access (OA) journals in library and information science. The results suggest that the number of web citations has increased from 41.60% of all citations in 1998 to 53.32% in 2002. But a substantial quantity of web citations (32.09%) was found to be missing. The percentage of missing web citations goes on increasing with each passing year -ten-year-old publications having the highest number of missing citations, i.e., 39.96% and five-year-old publications having the lowest number of missing citations (25.89%). 0.92% of citations had moved to a new URL address and 74.14% of missing citations resulted in an HTTP 404 (page not found) error.

Purpose -This study aims to examine the performance of Indian research Institutions' websites using webometrics by investigating their visibility, traffic ranks, number of links, time on site, Indian/Foreign users and page ranks besides focusing on the two designed hypotheses. Design/methodology/approach -The Council of Scientific and Industrial Research (CSIR) directory (www.csir.res.in/external/heads/aboutcsir/lab_directory.htm) is used to identify the research institutions in India. The directory lists 40 research institutions across India. However, Alexa did not offer required information for some of the websites due to very high traffic ranks, and accordingly the list is reduced to 21 research institutions. The data collected were analysed and tabulated to reveal findings in accordance with the desired objectives. Findings -The results reveal that global traffic ranks, number of page views, number of links and time on site of Indian research institutions are low. However, the page ranks are to some extent satisfactory. The traffic ranks of Indian research institutions differ significantly, whereas no major difference in the page ranks is found. Further, the results show that Indian research institutions' websites have not been able to attract foreign visitors given the calibre and reputation of these institutions. Originality/value -The results of this study will be useful for website administrators of research institutions in India and across the globe.
