E- Libraries 
An electronic library (also referred to as digital library or digital repository) is a focused collection of digital objects that can include text, visual material, audio material, video material, stored as electronic media formats (as opposed to print, micro form, or other media), along with means for organizing, storing, and retrieving the files and media contained in the library collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals, organizations, or affiliated with established physical library buildings or institutions, or with academic institutions.The electronic content may be stored locally, or accessed remotely via computer networks. An electronic library is a type of information retrieval system.

Z-Library (abbreviated as z-lib, formerly BookFinder) is a shadow library project for file-sharing access to scholarly journal articles, academic texts, and general-interest books (some of which are pirated). Individuals can also contribute to the website's repository to make literature accessible to as many people as possible. As of 22 October, 2021, Z-lib states that it possesses more than 8,930,000 books and 84,830,000 articles. According to the project's page for academic articles (at booksc.org), it claims to be "the world's largest e-book library", as well as "the world's largest scientific articles store". Z-library also describes itself as a non-profit organization sustained by donations.

ManyBooks was established in 2004 with the vision to provide an extensive library of books in digital format for free on the Internet. Many of the early eBooks are from the Project Gutenberg archives, which means you will be able to find a lot of classics on the site.

Over a decade later, we are still going strong in our mission to provide a valuable service to our readers. ManyBooks has grown into a platform where self-publishing authors have the opportunity to introduce their work to our community and new books are uploaded to our site daily - provided they comply to our quality standards.

In our daily newsletter, we keep our rapidly growing list of active subscribers up to date on the latest free and discounted eBooks that are available online. We always love to hear from our visitors, so if you have any questions or feedback, don't hesitate to contact our editor lisa.clifford@manybooks.net.

The ultimate goal of the Open Library is to make all the published works of humankind available to everyone in the world. While large in scope and ambition, this goal is within our grasp. Achieving it will require the participation of librarians, authors, government officials and technologists.

Imagine what a comprehensive, open library could be! A talented math whiz who lives in a rural community can explore the works of high math. An elderly person can have a large print edition of any book ever published. An innovative young scholar can publish a book directly to this great library on subjects that might not otherwise make it through the long and difficult publication process.

How can you help? Improve the records we have for the books you love – every record is fully editable by clicking the “edit” button on the page. If we don't have a record for a book, you can create one. If you're a library with digitized resources, tell us where they are and we'll point people to them.

Our hope is that libraries and individual book readers will join this project and together we can build towards universal access to all knowledge.

Project Gutenberg is an online library of free eBooks.
