It looks like a lively, lightly-moderated list here. As a long-term participant on Usenet as well as many email lists, this is nothing new to me and I feel perfectly welcome. :) My first question involves the book "On The Sensations of Tone" by Herman Helmholtz. I recently saw mention of it online and decided that since its copyright has long expired I might find it on the GP site. I don't see it, nor did I find the text elsewhere online, but further investigation (reading much of the PG FAQ) led me to this page with list of books in progress: http://www.dprice48.freeserve.co.uk/GutIP.html The relevant portion of that webpage is: Helmholtz, Hermann Ludwig Ferdinand von (31aug1821-8sep1894) The Mystery of Creation - Copyright cleared 23 Nov 1997 On the Sensations of Tone as a Physiological Basis for the Theory of Music - Copyright cleared 17 Sep 2003 How do I find the "real" status of this book, whose copyright was cleared seven months ago but is not yet online? If it's not actively being converted to text by someone else, I'd like to do it (as soon as I get my own physical copy). Apparently, I should email Mr. Price at the address indicated on that webpage to see what he might know, but I'd also like to know if I'm missing something in relation to this. Second question: Why are there two copies of Thomas Paine's "Common Sense" on the GP site? And a third: I just came across yet another copyrighted book online. All such books I've seen on the web are apparently put online legally by the author or with the author's permission. Is there a list of these books, perhaps as a part of an index of "all books online"? And yes, I know this is fairly tangential to the purpose of the GP, as most such authors generally choose to retain full copyright and have their books available ONLY on their sites, so they can have some control, such as using the site to advertise/selling physical copies of the book.
