Internet, computer-based worldwide information network. At the dawn of information age, professionals are experiencing new vigor in field of information collection, processing and retrieval. The internet considered as the electronic mobile library in cyberspace provides an almost universal infrastructure for accessing the information with almost global reach. The Internet is composed of a large number of smaller interconnected networks called internets. These internets may connect tens, hundreds, or thousands of computers, enabling them to share information with each other and to share various resources, such as powerful supercomputers and databases of information. During the 1990s the Internet has grown tremendously in the number of people using it and the amount of information contained on it. According to the Internet Society, a non-profit society that studies and promotes the use of the Internet, 134 countries had full internet connection and an additional 52 countries had limited access (for example, e-mail only) in 1996. Surveys performed by International Data Corporation and Matrix Information and Directory Services found that as of beginning of 21st Century there were between 53 and 57 million users of the Internet worldwide.
Accessing the Internet
Access to the Internet falls into two broad categories: dedicated access and dial up access with dedicated access, the computer is directly connected to the Internet via a router, or the computer is part of a network linked to the Internet. With dialup access, a computer connects to the Internet with a temporary connection, generally over a telephone line using a modern--device that converts the electrical signals from a computer into signals that can be transmitted over traditional telephone lines. A modern is needed because computers are digital, meaning that their signals are made up of discrete units, while most telephone lines are analog, meaning that they carry signals that are continuous instead of discrete. Once a signal has traveled over the telephone line, a second modern is required at the other end of the line to reconvert the transmitted signals from analog to digital. A great many companies, called Internet Service Providers (ISPs), provide dial-up access to the Internet for a modest fee. Examples of ISPs are America Online (AOL), the Microsoft Network (MSN), and CompuServe.
Academic Libraries Present Scenario
Academic libraries include college and university libraries. Commonly referred to as research libraries, they are often used by students and research scholar as a quiet place for study and research. The same use behaviour is common to most academic libraries. The college libraries has to deal with information resources in variety of formats and attempting to select the most appropriate and economically viable formats for providing access to information in their libraries.
There has been a more change in the academic libraries due to the revolution in e-resources era. The networked information and access to information resources rather than holdings have become the order of the day, all over the world academic libraries besides, individuals subscribe electronic journals to meet their expectation.
The academic libraries of all sizes and types are embracing digital collection, although most libraries will continue to offer both print and digital collections for many years to come. New purchases and purchases of journals, magazines, and abstracting and indexing services are heavily weighted towards digital, while digital books (e-books) are only beginning to become a present library collection. Libraries prefer digital resources for many reasons such as digital collection save the space and are relatively easy to maintain.
Growth of Electronic Resources
The most rapidly changing pervasive and publicized aspects of library and information studies are the electronic resources. …
