Library Genesis which is also called LibGen or Genesis Library, is a search engine for scientific papers and books on various topics. It allows you to access to paid content or books that are not digitized anywhere. In particular, PDF files distributed on Elsevier's ScienceDirect web portal are included. As of June 2018, the Genesis Library database claims to contain over 2.7 million books and over 58 million journal articles. No matter you're a student writing papers, a researcher searching for science reports, or a book worm finding nourishment for your mind, Library Genesis will satisfy you.
You can find almost any book and paper on Library Genesis. And when you find your targets, you can easily download them as PDF, WORD, EPUB, MOBI, DJVU, etc. In this post, we'll explain how it works, how you can get access to this amazing free library, how to use Library Genesis and how to download PDF books from Library Genesis for free.
The reason why Library Genesis is so powerful is it collects download links from it's 5 mirror websites. When a download mirror is broken or down, the site will fill up with another. In this way, Library Genesis almost guarantee accessible download links of every e-book you search for.
When you search for a book on LibGen, the search engine searches a few mirrors sites that actually hosts the book. When the search engine matches your search instruction with the book on those sites, you can get download links from the download mirrors. We'll show you how to download a PDF, EPUB, MOBI e-book from these mirrors in Part 2.
Step 3. Choose a PDF e-book from the search result. In the LibGen search result, you can see all files that the search engine has matched for you. The books are displayed by author(s), title, publisher, publish year, pages, language, size and extension.
LibGen provides more than one extension of their books, including PDF, EPUB, MOBI, WORD, etc. Generally speaking, EPUB and MOBI would be the most compatible format with e-readers like Kindle, iBooks, and Calibre Moon+ Reader. However, PDF is not only a compatible format for most readers and software but also more universal on document sharing and exchanging on the internet. So we highly recommend you to download the book as PDF format. If somehow you need to split the PDF e-book, you can use an online PDF Separator to achieve that.
Although Library Genesis is considered the most powerful free e-books search engine on the world, it has faced some legal disputes before and may be facing more in the future. It's always better safe than sorry, so we should collect some alternative sites as backup.
Project Gutenberg is an online library of over 60,000 free eBooks. You can read these e-books online or download them as EPUB and Kindle eBooks without any payment or registration. Project Gutenberg focus on older literature works for which U.S. copyright has expired, so they're more likely to avoid the legal dispute that LibGen has.
Open Library is a project for the collaborative creation of an online library based on a bibliographic database. The goal of Open Library is to create a website for every book published and the digitized version of paper books, most of which are PDF and EPUB formats. The e-books that Open Library contains covers a wide range of topics including Art, Science, Biographies, Religion, Music, Medicine, History, etc. To download a PDF or EPUB e-book, you'll have to register on Open Library first.
