LibriVox fans, volunteers and curious tourists may like to visit Distributed Proofreaders and offer their services there, or just send them a note of thanks. This group does much of the background work that has allowed LibriVox to exist – they are the proofreaders who get gutenberg.org e-texts into shap to publish (oh that should be: “into shape”).
And to boot they are a totally volunteer, distributed group (we like that, a lot).
Here’s their FAQ … oh and for LibriVox readers who find typos in the gutenberg texts, here what to do to help.
