This document defines and discusses digital libraries and e-libraries. It explains that a digital library is a collection of digital objects like texts, images, audio and video that can be accessed online or stored locally. Benefits include a vast selection of resources, instant global access, preservation of materials, and powerful search capabilities. However, digital libraries also face limitations such as reliance on internet access and electricity, inability to replicate the environment of a physical library, and copyright issues. In conclusion, digital libraries provide convenient learning access but are not suitable for all people and environments.
