Seeing the underlying value of having a unified interface to update users about library services and activities, most libraries have developed library portals. The paper aims to evaluate the contents and services of top ten NIRF ranked university library portals and score them in the classes of Excellent, Good, Average and Poor. Further, the study aims to investigate the most preferred type of content available on Indian university library portals. The top ten NIRF ranked university library portals were evaluated using a checklist based framework covering broad categories such as Information about general, information about the library’s physical collection, Information about subscribed e-resources, information regarding the library’s services, and Information regarding the use of social Web technologies. Findings suggest that six of the selected library portals were rated in the ‘Average’ class(scores 40-60 %), which shows that most of them lack essential user-oriented information. JNU’s library portal carries maximum information for their users scoring maximum University Score of 28(62.22 %). Among the selected library portals 49.23 per cent prominently provide information about the library’s collection, followed by general information(46 %) and information regarding library services(35.33 %). Only one portal exploits social networking features. The study report that the Indian university library portals suffer from issues like currency, transparency, visibility of collection, availability of online services, and uniformity. The findings of the study will help the portal development team to select the most common category of content describing information about services and facilities available on library portals. The existing portals can also improve their interface based on the findings of the present study. Assessment of existing university library portals of the national top ten university library portals in India is the first attempt to evaluate this kind of sample. The study’s value lies in its evaluation framework, that’s minimal in nature covering the minimum information categories that must be available on any university library portal.

This paper presents a careful review of studies underlining the impediments in digitization and digital preservation of cultural heritage resources faced by library professionals, archivists and project managers in digitization projects. A systematic and structured literature review based on the conceptual and empirical published studies on digitization and digital preservation is done to sieve out the barriers and challenges of digitization projects. The findings of the study revealed that most digitization projects suffer with impediments such as, inadequate funding, lack of national-level digital preservation policy and absence of technical infrastructure while digitizing and preserving the cultural and heritage resources. The originality of the paper lies in presenting the prominent constraints in digitization and preservation of cultural and heritage resources in consolidated manner otherwise scattered in several case studies. The findings will be of high significance for librarians and digitization project managers at the planning stage of their digitation projects.

PurposeThe purpose of the study is to evaluate certain characteristics of the videos of the software Koha and DSpace posted on YouTube. Since YouTube has the potential to provide the content creator to share their knowledge and experience through their content which has become much more beneficial to the information seeker. Nowadays, people search for queries or tutorial videos on YouTube very often to earn a better understanding of the term. Sentiment analysis of the viewers' opinion of the videos is another purpose of this study.Design/methodology/approachDataset for evaluating the characteristic of the videos of Koha and DSpace was extracted by using Webometric Analyst by creating YouTube API. Once retrieval of data was completed, a manual verification was enhanced to filter out spam videos unrelated to the scope. After the confirmation of authentic relatable videos, seeking the video's id as query, the comments per video were extracted using Webometric Analyst. For opinion mining, the Parallel Dots API web service was used in Google Sheets as an addon function. The sentiment, multilingual sentiment, emotion, intention and word frequency of the viewers' opinion was examined with the help of certain default functionalities.FindingsWebometric Analyst extracted a total of 461 and 397 videos of Koha and DSpace, respectively, uploaded on the YouTube platform. The findings of the study indicate that the growth rate of videos on Koha is decreasing, while the number of videos uploaded on DSpace is gradually increased in the last 10 years. The highest number of videos posted in 1–20 min duration category with mostly high definition (HD) with standard YouTube license and prominently in the English language. The sentiment analysis of the total extracted comments on Koha and DSpace videos found to be 2043 and 862 comments, respectively, among whom “Positive” comments are mostly found and with “Happy” emotion can be highly detected with most supportive “Feedback” intention on both Koha and DSpace videos. The top word frequency signifies that the users of both the software are using the comments section of the videos on YouTube to ask and provide troubleshooting help to each other.Research limitations/implicationsThe present study has some limitations too; the dataset for the study includes only those videos whose title, description or keywords sections had the query terms “Koha” or “DSpace” there are chances that some videos would have been left out from the dataset related to these software.Originality/valueThis is the first paper to evaluate the characteristics and sentiment of both the videos Koha and DSpace. Through this, the popularity, likeness and dislike and the impact of the contents of the videos uploaded will be disclosed, and creators can make an improvement by referring this, and the seekers will adapt to the use of correct and authentic information.

The thought of Ambedkar, explicitly or implicitly, has fascinating ecological dimensions. His ideas on the relationship between human beings and nature are useful to put equity at the centre stage of environmental discourse. Environmental problems and degradation for Ambedkar are not only because of over-exploitation of natural resources, but also due to iniquitous access of different social groups to the resource base. Particularly on the issue of access to drinking water to socially marginalized sections such as Dalits, Ambedkar reflected deeply in his intellectual and activist life. This article proposes that the ecological dimension of Ambedkar's thought offers a theory of environmentalism from below which is useful to capture differential impact of environmental problems on socially marginalized sections in general and Dalits in particular.
