PurposeThe paper seeks to examine the use of electronic information services (EIS) among the users of the Indian Institute of Technology (IIT) Library in Delhi, India.Design/methodology/approachBoth questionnaire and observational methods were used for data collection where 300 valid samples were collected. The analysis of data collected covers awareness of EIS services, use of e‐journals, advanced search facilities, acquaintance with electronic information sources, the purpose of using e‐information, problems faced by the users while using EIS, infrastructure facility available and satisfaction level of users.FindingsThe study found that Boolean logic and truncation are the most often used search facilities by IIT users. Lack of printing facilities, terminals and trained staff are the major reasons that would discourage users from accessing the EIS. The survey also reveals that some 60 per cent of users face difficulties while browsing e‐information.Originality/valueThe paper provides suggestions for the further improvement of EIS to fulfill the information needs and requirements of users at the IIT Library, Delhi.

The Z‐DNA forming potentiality of native calf thymus DNA using spectrophotometric measurements and diethyl pyrocarbonate reactivity have been investigated. The [image omitted] value was evaluated from absorbance ratio for B‐ and Z‐DNA and compared with the values obtained for native DNA. The results suggest that native DNA undergoes B‐ to Z‐/Z‐analogous transition to an extent of 20 per cent under constraint conditions. Possible Z‐DNA formation was also characterized by hyper‐reactivity of native DNA towards diethyl pyrocarbonate in aqueous solvent. The thermal melting profile of native and modified DNA and nuclease S1 digestibility data, in addition, reflects B‐ to Z‐/Z‐analogous transition in native DNA.

Purpose The purpose of the study is to assess the familiarity and utilization of open access resources among library users of Cochin University of Science and Technology (CUSAT), Kochi, and Pondicherry University (PU), Puducherry. Design/methodology/approach Data for the study were collected via a well-structured questionnaire. For this study, 250 questionnaires were administered among library users of each CUSAT and PU through incidental sampling. From CUSAT and PU, 180 and 160 questionnaires, respectively, were considered for data analysis. Findings The study reveals that majority of the respondents, i.e. 77.78 and 80 per cent of CUSAT and PU, respectively, believe that they are familiar with the concept of open access (OA). 70.56 per cent respondents from CUSAT and 71.88 per cent users from PU are aware that their library has an OA repository. However, majority of the respondents, i.e. 65 and 70.63 per cent users from CUSAT and PU, respectively, use OA resources. Among OA resources, electronic theses and dissertations are the most preferred ones consulted by 56.67 and 62.50 per cent respondents, respectively, from CUSAT and PU. 60.56 per cent respondents from CUSAT followed by PU (52.50 per cent) cited “screen reading” as a main barrier in accessing OA resources. Originality/value Both the universities under study have created and maintained the OA institutional repository for disseminating their institutional intellectual output. This study explores awareness and use of OA resources among library users of CUSAT and PU. The study concludes with some suggestions for utmost utilization of OA resources among library users.

Purpose -The purpose of this paper is to determine the extent to which research scholars at Central Science Library, University of Delhi are aware and make use of e-journals. Design/methodology/approach -A survey was designed to collect basic information about the level of use of electronic journals as well as other factors contributing to and associated with their use. A well-structured questionnaire was administered among research scholars to collect the necessary primary data, keeping in view the objectives of the study. Findings -The findings clearly reveal that more than 60 per cent of users in the Central Science Library are using e-journals weekly for the purpose of research. Printed journals are consulted by the majority of users compared with e-journals. Keyword is the most popular search method for searching e-journals among research scholars, whereas the date of publication carries the least percentage among all the options. However, if is found that slow downloading of PDF files is the major problem that would discourage users while using e-journals.Research limitations/implications -The present paper consists only of e-journal users and the geographical area is restricted to the CSL at the University of Delhi. The scope of the paper could be extended to additional centrally funded universities. An intra-comparative study could also be made between some select central and state universities for users of e-journals. Originality/value -There are a number of studies on the use of e-journals, but this is the first of its kind within Delhi University. As such, it should pave the way for research in other Indian universities as well as elsewhere.
