The steady two-dimensional laminar boundary layer flow, heat and mass transfer over a flat plate with convective surface heat flux was considered. The governing nonlinear partial differential equations were transformed into a system of nonlinear ordinary differential equations and then solved numerically by Runge–Kutta method with the most efficient shooting technique. Then, the effect of variable viscosity and variable thermal conductivity on the fluid flow with thermal radiation effects and viscous dissipation was studied. Velocity, temperature and concentration profiles respectively were plotted for various values of pertinent parameters. It was found that the momentum slip acts as a boost for enhancement of the velocity profile in the boundary layer region, whereas temperature and concentration profiles decelerate with the momentum slip.

Numerical Solution is applied to find the solution of the boundary value problem.

Velocity, heat transfer analysis is done with comparing earlier results for some standard cases.

The systematic literature review aims to highlight the transformative influence of mobile technology in reshaping library services for Library and Information Science (LIS) professionals and users.

The selection of relevant literature utilized the PRISMA-20 guidelines and a systematic literature review, wherein 39 articles were meticulously examined from a pool of 198. The inclusion and exclusion criteria were applied to articles retrieved from the Scopus database and Google Scholar, focusing on data from 2018 to 2023 and excluding all the literature except journal articles.

The results demonstrate a significant awareness among LIS professionals and users regarding adopting mobile-based library services. Nonetheless, the adoption of mobile technology in libraries faces impediments from internal and external factors. These challenges encompass the need for coherent policies and practical issues such as insufficient financial resources, limitations in infrastructure, unpredictable electricity and Internet connectivity. The study also highlights concerns related to data security, the digital divide, a shortage of IT experts and inadequate staffing. The findings suggest that libraries must navigate this evolving landscape to provide improved and more accessible services to their users.

This study addresses a gap in the existing research by contributing to the literature on using mobile technology for accessing library services and resources. The findings aim to assist LIS professionals in developing plans, policies and strategies for implementing mobile-based library services.

The results of this study contribute to improving and expanding current mobile-based services in libraries, ensuring that information and resources are universally accessible “on the go environment.”

The purpose of this paper is to explore legal information requirements of the legal community in India for a proposed online legal information system tailored to the Indian environment.

A needs assessment survey was conducted using a structured questionnaire circulated among 750 respondents from eight institutions in Delhi. A total of 397 filled-in questionnaires were personally collected by the investigator, showing a response rate of 52.9 per cent. All these questionnaires were selected for analysis and interpretation of data. Responses to 45 questions were analyzed and presented in the form of tables and figures using various statistical techniques.

The findings of the study show that majority of the respondents felt they faced a number of problems in using online legal resources such as accessibility of legal information in legal resources, lack of online help features, description of legal information sources, search screen too confusing and poor website design. In addition, respondents highlighted that access instructions on the online resources are not clear. Lack of expertise and insufficient knowledge of information and communication technology in using legal databases are also major hurdles. Majority of the respondents are somewhat satisfied in using open-access and commercial legal information resources and not aware of open-access resources in the field of law. Model online legal information system (OLIS) was designed and developed based on the findings drawn in the needs assessment survey to empower the common man with legal resources at no cost, and foster research in the field of law.

The model OLIS contains only a sample collection. It is expected that the proposed system will be implemented on a wider scale, so that lawyers, research scholars and common people can benefit.

The findings of the study will help libraries to subscribe to legal information resources and to design robust OLIS suitable in the Indian context. It is anticipated that the needs assessment survey of OLIS will help government agencies and law libraries to understand the problems of the legal fraternity in accessing legal information.

The present study designed a model OLIS for the Indian environment (www.olisindia.in) to aid the legal community in India, enabling them to save their valuable time. This system will help and foster interdisciplinary research learning and can be used as a tool for learning the basic concepts, as well as help deliberate on the emerging areas in the field of law.

This study aims to discuss the metadata structure of an online legal information system (OLIS) developed to suit the Indian environment. The OLIS is accessible online at www.olisindia.in. It contains several types of legal information resources to help lawyers, research scholars, students and the common user. The open-access OLIS helps the users to get the required information expeditiously. Dublin Core (DC) metadata standard was selected to create records in the OLIS because of ease of use and high adoption rate.

The OLIS was designed using the system analysis and design method after a needs assessment survey conducted in eight major legal organizations in Delhi. The OLIS, accessible at www.olisindia.in, was accessed to identify and validate the metadata elements with the DC metadata standard.

This paper discusses in detail the metadata structures of the OLIS. The system contains 15 types of resources relating to judicial and legislative information. Each database has a different metadata framework so that information desired by the legal community can be retrieved with precision and quick recall. In addition, a number of functions, such as latest news, online help, Frequently Asked Questions, query submission, online discussion forum for help and video tutorials, have been integrated into the OLIS.

The study guides law libraries and library professionals to follow metadata standards in building an open-access database and also provides a legal resources metadata framework that enables them to select suitable resources for their libraries.

The study confirms that the metadata elements set for managing judicial and legislative information are different compared to other types of scholarly information. The study can help newly established law university libraries to build legal information systems to suit their environment and satisfy the information needs of the diverse law community.

This paper aims to present recently published resources on information literacy and library instruction providing an introductory overview and a selected annotated bibliography of publications covering all library types.

This paper introduces and annotates English-language periodical articles, monographs, dissertations and other materials on library instruction and information literacy published in 2016.

The paper provides information about each source, describes the characteristics of current scholarship and highlights sources that contain unique or significant scholarly contributions.

The information may be used by librarians and interested parties as a quick reference to literature on library instruction and information literacy.

The purpose of this paper is to identify the most popular places, gadgets, searching tools and techniques adopted by users of Dr Y.S. Parmar University of Horticulture and Forestry (DYSPUH & F), Nauni, Solan, Himachal Pradesh, while searching electronic information resources (EIRs).

A survey was conducted with the help of a structured questionnaire used as a data collection tool.

It is found that department/office chamber (42 per cent), hostel (29 per cent) and home (26 per cent) prove to be the most popular places of access. Majority of users use laptops to access and read EIRs. Among all popular platforms, users of DYSPUH & F library prefer to use “search engines”, and “Google” proves to be the number one search engine. Majority of users search the information through “title” followed by “keywords/subject terms”. The users are not yet well-versed with most of the advanced search techniques, as less than half of them are able to use only Boolean operators, and less than 10 per cent of them claim to know other search techniques. Majority of users have learnt to use information search and retrieval skills through self-study.

Only one agricultural university of northern India was surveyed; hence, the results cannot be generalised for the entire northern region of the country.

The findings will help the library authorities to see what are the prime areas of concern so far as the search discourse and accessibility of e-resources is concerned.

No such survey has been conducted in the University till date.

The purpose of this paper is to examine the use of e‐journals by the users of IIT Delhi and Delhi University.

Survey research was conducted to access e‐journal use among IIT Delhi and Delhi University users. A stratified random sample method was used for selection of respondents. The survey was conducted through a structured questionnaire taking a random sample of 300 users (PG and PhD) from different disciplines of IIT Delhi and Delhi University libraries and the response rate was 66.66 per cent. The questionnaires were administered personally among the users of IIT Delhi and Delhi University during the survey period (March‐May 2011).

From this survey it was found that most of the users are aware of e‐journals and they are not only using them for building and updating their knowledge but also for collecting relevant material for their study and research purposes as information can be acquired expeditiously through e‐journals. The main aim of consulting these journals is for retrieving information regarding research, publishing research papers and manuscripts, assignments, presentations, seminars, and largely to update their own knowledge. However, this study also reveals several inherent problems especially with the use of e‐journals e.g. slow downloading as revealed by maximum IIT Delhi and Delhi University users. Other mechanical deficits like non‐availability of a particular issue, lack of training and limited access to terminals are also present while using e‐journals.

The present study consists only of e‐journal users of IIT Delhi and Delhi University. The geographical coverage is restricted to Delhi. The responses have been taken from users and the data have been collected during the months of March‐May 2011 only.

The problem is selected by the investigator to understand the use of e‐journals by IIT Delhi and Delhi University users so that libraries can make further improvement in their e‐journal services depending upon the results and suggestions.

The paper provides suggestions derived from the analysis of data which in turn will help to enhance the use of e‐journal services and fulfill the needs and requirements of users in the libraries of IIT Delhi and Delhi University.

This study aims to investigate the quality level of the leading three Public Administration Institutes’ (PAIs) websites in the Arab world.

A convenient sample of 203 Jordanian Government employees answered the questionnaire that assessed five quality dimensions (content, navigation, interface design, accessibility and educational purpose) for each website.

The website of PAI of Kingdom of Saudi Arabia recorded a high level in all quality dimensions, whereas the website of PAI of Jordan recorded moderate quality in all dimensions except for accessibility; the website of PAI of Egypt recorded a high level in all quality dimensions except for the educational purpose. Based on the qualitative analysis, participants agreed that the PAI website has the best quality, accessibility, navigation and design compared with the Egyptian and the Jordanian PAIs websites.

Designers of PAI websites should consider end users’ needs and regularly assess the website’s usability. PAIs developers should also establish more interactive portals to provide transparent and effective electronic services to users. The findings are significant in helping policymakers better understand the importance of distance training and learning using websites and platforms.

Developing a high-quality website enhances the relationship between the government and its employees, consequently establishing the credibility and trust of citizens in public services.

To the best of the authors’ knowledge, this is the first study that measures the quality of PAI websites in the Arab world. The findings provide more cross-culture evidence for the e-government and digital literature in helping policymakers develop more technology interactive platforms.

The purpose of this paper is to highlight the importance of quantitative and qualitative analysis of the usage of e‐resources in academic libraries. It also describes various studies undertaken to study the users' behavior and attitude towards e‐journals.

The paper provides a comprehensive review of the recent published literature on the importance of the usage statistics of e‐resources subscribed to by the academic libraries.

The findings show that the usage statistics help in studying and evaluating the users' behavior in an online environment. The library services can be extended and modified, to reflect user interests suiting the users the most, in the light of the evaluation and analyses done.

The paper has pertinence and wider implications for library staff engaged in providing e‐resources' services to readers.

The purpose of this paper is to identify the frequency at which the users of agricultural libraries of Northern India tend to use the e-resources and explore the time they invest on average in a day in using e-resources. An effort has also been made to examine the state wise, university wise and user category wise tendency w.r.t. the frequency at which they use e-resources and the average time in a day they spend on their use.

A survey was adopted to conduct the study and a questionnaire was used as a data collection tool. The investigator also interacted with the librarians through telephone and also resorted to the e-mail communication to substantiate the responses and seek certain clarifications thereof. Statistical Package for Social Science was used to analyse the data on an empirical basis. χ² test was used to derive an association between the variables and test the level of significance thereof.

It is found that the users of North Indian agricultural libraries have got a great tendency to use e-resources as majority of them are seen to use them “daily” and “2-3 times a week”. They prove to be voracious, prudent and sensible users in the sense that they spend 2 hrs in a day, 1 hr in a day and even 3 hrs in a day on usage of e-resources and thus go at par with the use pattern recorded in other domains of knowledge across India. No remarkable difference is witnessed among different categories of users w.r.t. frequency of use and the time spend on use of e-resources.

This study has been conducted on e-resources only. Response to a similar set of questions need to be collected from the same library users to consolidate the facts about the print form of information and thus carryout a comparative study.

This is first work of its nature in Northern India with domain as agricultural libraries. The outcome of the study will enable the librarians to judiciously decide about the proportion at which the two formats of information resources need to be acquired and the facilities the libraries need to create for adequate, smooth and reliable access to two formats of information.
