I thought I would start this small corner of the internet off by mentioning an online community I've been visiting frequently of late - this being Librivox. (www.librivox.org)
I first encountered the Librivox site shortly after first discovering the works of H.P. Lovecraft, and looking for more information on the Cthulhu Mythos stories for which he is renowned. At the outset I was simply delighted to find a collection of multiple hours worth of his works recorded into mp3 format and ready to go. (Link) It just so happened that I was searching for something to occupy myself during the interminable twice-daily bus trips to which I was at the time accustomed, so this discovery on my part was welcome indeed.
So I proceeded to download this collection, and copied it to my iPhone to enjoy on my trips to and from work. Thoroughly enjoying the efforts of the volunteers, as I realised they were from the disclaimer inserted at the beginning of each recording, I resolved to visit the site myself and understand more about how this community.
The members of this community have taken upon themselves an ambitious goal. If I may quote their stated objective: "To make all books in the public domain available, for free, in audio format on the internet." I have always been passionate about reading, and so I read about exactly how they expected to undertake this task. I quickly found myself in concert with their stated mission of being an independent, not-for-profit volunteer group, whose members have recorded many works of fiction, poetry, etc. in a significant number of languages.
Since this first experience with Librivox, I personally have enjoyed a number of their recordings. As mentioned, I swiftly devoured the collected PD works of H. P. Lovecraft, and have latterly moved on to those singularly excellent works of Sir Arthur Conan Doyle - The various stories featuring none other than Sherlock Holmes. I have also recently purchased a new pair of headphones, such that I might personally contribute in some small way to this community with which I find myself so enamoured.
