DIGITAL LIBRARY

1. introduction to digital library

.A digital library is a collection of digital artifacts, such as books, articles, images, videos, and other types of media, that can be accessed and used through a computer or electronic device. Digital libraries can be created and maintained by individuals, institutions, or organizations, and can be made available to the public or restricted to a specific group of users. They can also be in various forms such as online, offline, or hybrid. Digital libraries can provide access to a wide range of information, making it easier for people to find and use the resources they need. They also have the potential to improve access to information for people in remote or underserved areas, and can help to preserve and make available cultural heritage materials

1.1. purpose of digital library

The purpose of a digital library can vary depending on the specific library and the organization or group that manages it. Some common purposes of digital libraries include:

1. Providing access to a wide range of information, including books, articles, images, and other types of media, in a convenient and easily searchable format.

2. Preserving and making available cultural heritage materials, such as historical documents, manuscripts, and photographs.

3. Improving access to information for people in remote or underserved areas, who may not have easy access to physical libraries or other sources of information.

4. Facilitating research and scholarship by providing access to a wide range of scholarly resources and tools for data analysis and visualization.

5. Providing a platform for digital collections and digital archiving, allowing the preservation and sharing of digital materials in perpetuity.

6. Supporting education by providing access to educational resources such as textbooks, videos and online courses.

7. Supporting the work of government and other organizations by providing access to public records and other information.

8. Supporting the work of community organizations, by providing access to information and resources that can help to promote social and economic development.

1.2. Historical background of digital library

The idea of a digital library has its roots in the early days of computing, when researchers began to explore the potential of using computers to store and manage large collections of information. The first digital libraries were created in the 1960s and 1970s, and were primarily used by researchers in the fields of computer science and library science.

One of the earliest and most influential digital library projects was the Project INTREX, led by Douglas Engelbart at SRI International in the 1960s. This project aimed to develop a system that would allow researchers to access and share information more easily. Another early project was the Interlibrary Loan Photoduplication Service (ILLPS), established in the 1970s by the Library of Congress and the National Library of Medicine. This project aimed to digitize and make available copies of books and other materials held by libraries around the country.

In the 1980s and 1990s, advances in technology, such as the development of the Internet and the World Wide Web, led to the creation of more sophisticated digital libraries. Some of the most notable digital libraries developed during this time include the Online Computer Library Center (OCLC) and the National Science Digital Library (NSDL).

The development of digital libraries continued to evolve with the advent of new technologies such as the increasing use of cloud computing, big data, and artificial intelligence, which has made it easier to manage and share large collections of digital information. Today, digital libraries are widely used in many different fields, including education, research, government, and business, to provide access to information and resources that are not easily available in traditional libraries

1.3. Nature of digital library

A digital library is a collection of digital materials, such as books, articles, images, videos, and audio recordings, that can be accessed and used by users through the internet. Digital libraries can include a wide range of materials, such as primary sources, scholarly works, and government documents. They can be created by institutions such as libraries, museums, and archives, as well as by organizations and individuals. Digital libraries can offer a variety of services, including search and retrieval, preservation, and access to a wide range of materials. They also allow users to access materials remotely, which is particularly useful for people in remote or underserved areas. Additionally, many digital libraries are also open access which means that the materials are freely accessible to all users without any restriction.

2. DIGITAL INFORMATION RESOURCES

Digital information resources refer to the various types of digital content that are available to users through the internet. These resources can include a wide range of materials such as:

· Audio and video materials: podcasts, webcasts, music, and videos in various formats such as MP3, MP4, etc.

· Images: photographs, illustrations, maps, and other visual materials in various formats such as JPEG, PNG, etc.

· Databases: collections of data in various formats such as CSV, JSON, etc.

· Web resources: information and resources available on the World Wide Web, including websites, blogs, and social media platforms.

These resources can be accessed through digital libraries, online databases, and other websites. They can be used for research, education, personal use and professional development.

2.1. Meaning of information resources

Information resources refer to the various types of materials that contain information, including both digital and non-digital resources. These resources can include:

· Books, journals, newspapers, and other print materials
