DELNET Developing Library Network(Full Notes,With Questions )

Developing Library Network
Delhi is growing as a major center of information resources in India. These resources cater both to the specialized and the general users. They are located in activities, information and documentation centers, institutional libraries, research libraries, government libraries, public libraries, department libraries besides the libraries of the universities, colleges and schools. During the recent years, increase in information has led to increase in the demands of the users. It has been noticed that in this area of information explosion, libraries in India are generally ill-equipped to handle and retrieve information effectively, the financial resources and the space requirement for housing library collection are limited in almost all of the libraries. No a single library can afford to house every necessary document even in the area of its interest. Resource sharing, thus assumes great importance at this juncture the option left with the forward looking librarians has been to promote the sharing of resources by automation and networking. With this objective, in January 1988, the India International Center initiated efforts for the establishment of Delhi Library Network (Now Developing Library Network).
                     DELNET is the first operational library network in India. It was started as a project of the India International Center in January 1988 with the initial, financial and technical assistance by National Information System for Science and Technology (NISSAT), Department of Scientific and Industrial Research, Govt. of India. It was registered as a society in June 1992 under the Societies Registration Act of 1860 and is currently being promoted by the National Informatics Center (NIC), Planning Commission, Govt. of India and India International Center, New Delhi.

             DELNET has been established with the prime objective of promoting resource sharing among the libraries through the development of a network of libraries.

DELNET Activities/Services
1. Promotion of Database Creation
For effective networking, standard bibliographic data should be available in machine readable form with the libraries. So, efforts were made from the very beginning to promote the standardization of databases in the DELNET libraries. Experts were sent to the libraries to solves day-to-day problems. A panel of experts was seeing maintained for this purpose. Regular meetings of the librarians and computer specialists were organized to discuss mutual problems and the areas of cooperation. Nevertheless, there have been some libraries in Delhi that took keen interest in database creation on their own. But the practice of regular meetings for database creation and resource sharing continue. DELNET provides technical assistance to member libraries in the following areas:
  • creation and maintenance of bibliographic databases

A major breakthrough has been achieved by DELNET with the launch of DELSIS, a powerful library networking software. DELSIS (DELNET System for Information Services) is an integrated modular system, which supports DELNET online databases.
It has been developed by DELNET on a Relational Database management System called BASIC plus, a product of Information Dimension Inc. of USA, which has been provided to DELNET courtesy National Informatics Centre, New Delhi. It handles not only the Online Public Access Catalogue (OPAC) but also has the administrative tools for building up the union catalogues on BASISplus. It provides powerful and extensive facilities for online enquiries for books, serials, biographical details about the specialists and supports the cataloguing of books in Indian languages.
Features of DELSIS:
  • DELSIS is a user friendly menu driven package
  • Its versatile options allow the users to retrieve the information quickly.
  • It contains the modules for Online Public Access Catalogue as well as the modules for the creation of databases e.g. addition, deletion, inserting of records etc.
  • The Online Public Access Catalogue (OPAC) components of DELSIS can meet the needs of the users, irrespective of whether the user has little computer experience or is familiar with using computers to perform various library tasks.
DELNET has released the DEL-WINDOWS version 1.0 after the successful creation and implementation of DELSIS Unix version. It is an efficient tool for creating and retrieving bibliographic databases and catalogues.
DEL-WINDOWS can convert the simple PC into a powerful management information system.
Some of the salient features are:
  • It is simple and easy to use. The novice library professionals and end users can interact with the software without any prior training.
  • It is user-friendly with adequate windows-menus for data inputting and search capabilities.
  • It provides the option for creating the bibliographic records either using ECF or the MARC format.
DELNET has opened a new chapter in the information retrieval procedure by devising a new database access mechanism through DELSEARCH. It is an off-line remote database access system through E-mail. It is the first of its kind and is the most economical and user-friendly remote database access system. It helps institutions, information specialists, research scholars, librarians and users interested in bibliographies and tutorial information on South Asia. It allows them to search the DELNET union catalogues through E-mail and is a great tool for research scholars. The software is developed on UNIX platform and allows the users to send their search requests through E-mail. As soon as the query is received by the system in the form of an E-mail, the respective databases are searched for the query word and the results are returned to the addressee immediately. The searching of the database does not require any human intervention and the searches are done by the system automatically.
The Future of DELNET                                                                                                
DELNET is very promising. Its membership with India and outside India is going to take a quantum jump. The DELNET databases are growing in number and size and as a variety of information on South Asia is becoming available through DELNET, it is expected that all institutions outside India specializing in South Asian studies to take DELNET membership. DELNET databases are going to be accessible through INTERNET which will made accessibility very fast. INTERNET users in India are increasing and it will increase DELNET presence in different parts of India. DELNET has already created software, viz. DELDOS and DEL-WINDOWS for creating MARC records.
These software will so on be developed to perform library operations as well. There developments are likely to give more revenue to DELNET and provide justification for more and more libraries to join DELNET. As a resource, it is hoped the DELNET will grow faster as a service based resource sharing model in India.
