People at ebooksgratuits can clear for PG those books for which they have TP&V. They can clear many more books than you because they come first: if they have a book that is easily clearable, they clear it before you have a chance to chip in.... But to clear a book with rule 1 (pre-1923) it is not strictly necessary to have a pre-1923 book, it is sufficient to have a book that says that it reproduces the content of a pre-1923 book. For example, it can say that the book was originally published in xxxx. Something like "Unabridged edition" too might be enough, if you can prove, e.g. through a catalogue search, that the original was published before 1923. I have cleared books from modern reprints in this way. Then you have to follow the detailed instructions given in the PG FAQ, in http://www.gutenberg.org/faq/V-62 . Carlo Traverso
