This is a great time to be a reader.
Especially if you’re a fan of older works, classics and forgotten wonders that have slipped into the public domain, and one of the greatest resources for these books is Project Gutenberg.
Founded in 1971, the Project is dedicated to preserving and making books available via digital format and distributing them freely over the Internet. According to their Wikipedia page, as of 2013 they have 43,000 works in their collection. Most of their offerings are available in multiple formats; including PDF, HTML, and EPUB.
There are some real treasures available thanks to the Project; from swashbuckling classics like The Three Musketeers, and Captain Blood, to early science fiction works such as those by Jules Verne and H. G. Wells. Hard to find masters of the weird like Lord Dunsany and William Hope Hodgson also have stories available and for more contemporary science fiction you can acquire books by the great E. E. “Doc” Smith and H. Beam Piper.
In addition to the original Project Gutenberg there are two other affiliated projects worth looking into; Project Gutenberg Australia and Project Gutenberg Canada. Each has its own library and if you can’t find what you are looking for on one you may have luck with the others.
So grab your tablet, e-reader, or laptop of choice and dig in.
