Although digital technology growth rapidly in the 21st century, but the importance of library is still there for its users. The rapid growth of information technology has considerably increased our capacity to process information and exponential growth in the information sector. The effect of information technology rises from its hallmarks such as enabling technology which can be applied in a different range of circumstances, the capacity of the technology increased very fast ; and the cost of the technology falling rapidly. Ambience of libraries needs to be changed because the documents of library is moving toward a digital platform and Internet access of library documents is becoming more user friendly. The implementation of modern technology in libraries is very important now. Keywords: Library, digital , knowledge, information technology. INTRODUCTION: The transformation from traditional library to digital library is a latest trend for the libraries in the present world. Digital library development requires in each sector executive and civil-society frameworks, to conjoin in promoting its creation and usage. Basic infrastructure for connectivity and interoperability, including funding, man power, workshop and leadership must be in favour of providing more digital projects . The new generation, which is known as millennials or netizens, is more user friendly in online working environments. The demands of the users have increased rapidly. Currently the users don’t want the content with place- based library services as they want library and information services beyond the four walls of the physical library. It is more desirable for the libraries to transform as per the expectations and demands of their user society. Libraries have to implement new technologies for providing innovative information services in order to retain their existing clientele and attract new ones. The fifth law of library science by Dr. S. R. Ranganathan “Library is a growing organism” is true to the environment of the modern library that means a library should be a dynamic institution that is never static in its perception. Types of Modern Libraries: According to the mode of services rendered to the readers; libraries are broadly divided into three types: i.Automated Library ii.Digital Library iii.Virtual Library i.Automated Library: An automated library system usually consists of a number of functional elements, such as acquisitions, circulation, cataloguing, series and an OPAC (Online Public Access Catalogue). An “integrated” library system is an automated system, in which all of the functional elements share a basic bibliographic database. Library work compries of a number of inter-related activities and the data generated during these activities are of repetitive in nature and useful in different sections. The Manual work involves recurring the same task in different sections of a library. The aim of automation is to consolidated these tasks and minimize reprise of work. ii.Digital Library: Digital library, is an online library, an internet library, a digital repository, or a digital collection of online database of digital objects that can include text, images, audio, video or other digital media formats accessible through the internet . It is also called a repository containing different content types ranging from research papers, reports and newspapers. Institutional repositories are not exactly digital libraries but digital collections that capture, collect, manage, disseminate and preserve scholarly work created by the members of an institution. The open source software movement has created digital library and institutional repository speeded the digital library creation process. Libraries are today playing an important role in the creation of institutional repositories because of open access feature. Digital libraries are store contents in electronic formats and manipulate large collection of these contents in very productive way. Research into digital libraries is research into network information systems, concentrating on how to
