Many articles on here say that a particular book is available on Project Gutenberg. This post contains some basic information that someone who is unfamiliar with the enterprise may find useful.
Project Gutenberg websites host thousands of free-to-read books that are in the public domain. Their copyrights have expired. They can be read online in various languages, formats and editions. Books can even be downloaded from the digital library.
There is a lot of general information about Project Gutenberg in Wikipedia and on the Project websites themselves. It is best for interested people to go direct to the sources and look at the rules, the catalogues and the search and other options, but I want to say a few things about my experiences of using this wonderful resource.
I prefer paper books, preferably with the original illustrations, but have little space for a library of my own. Project Gutenberg is an ideal place to find the classics, some old friends and books whose printed versions are very expensive or unavailable. Some of the eBooks even have illustrations.
I may want to refer to certain books from time to time; going to Project Gutenberg saves me from having to keep getting them from the public library or storing my own copies. It is often much easier to search the digital copies for remembered topics or phrases than it is to try to find something in a printed book.
