There are countless sites where you can download free books. Of course, the format for download is electronic, and the languages ??in which these books are available are diverse, with those written in international circulation predominating. However, you will find countless books written in Romanian as well. What's more, these sites are legal.
We offer you a short collection of sites that offer free books from all categories. We do not intend to exhaust the subject, so we invite you to bring us other suggestions in the comments section. The ones we recommend below are known from personal experience. You can read about GNU / Linux or topics related to history, science, art, religion, philosophy, etc., you have time.
Project Gutenberg (http://www.gutenberg.org/)
More than 45,000 books in electronic format can be downloaded or read online thanks to the project supported by (PGLAF) Project Gutenberg Literary Archive Foundation. The site was founded, according to Wikipedia, in 1971, by Michael Hart. Its purpose is to digitize, archive and distribute cultural works in public ownership.
The site is designed to be as intuitive as possible, there is even a top 100 of the most downloaded books, but also authors, updated daily, 7 or 30 days, as well as an offline catalog only good to download and studied at home, on tablet or computer. Under the field where you can search for authors or book titles I found a very useful tool that presents the latest books added to the site. Therefore, the Gutenberg Project is our first recommendation.
Free-Ebooks (http://www.free-ebooks.net/)
At this site it is necessary to register in order to make the most of what it offers. The categories are diverse, and the number of books available for free download is large. The site is intuitive and can satisfy the most demanding tastes in terms of diversity. EPUB or Kindle materials are also available for the VIP category.
Scribd (https://www.scribd.com/)
For Romanians, Scribd is more than known and used, regardless of whether you want to read about Ubuntu. Debian or Linux in general or about the work of a classic. As with the previous site, you must register and, among the existing subscriptions, you can download free content provided you upload something to the site. The diversity is great, and among the languages ??in which you can discover and download books is Romanian. You can also buy books.
Free computers Books (http://freecomputerbooks.com/)
As the title suggests, this site offers you an impressive collection of free books whose subject is related to the world of computers. Basically, in the over 150 subcategories you will discover books that address topics such as programming languages, mathematics, technical books, tutorials, etc.
Wikibooks (https://ro.wikibooks.org/)
This project does not offer you books in electronic format, but an impressive and diverse collection of information. Available in almost all important languages, including Romanian, the site aims to offer the best possible experience for everyone. According to its own description, posted on the site, Wikibooks is a free library, developed collaboratively by volunteer participants. Anyone can edit the pages in Wikimanuale, so that mistakes or inaccuracies that appear in articles dealing with topics that are familiar to you, remain only if you decide not to correct them.
Wikipedia (https://ro.wikipedia.org/)
There is nothing more to say about this site, accessed by almost every Romanian.
