Awesome catch, Anya! I ran into just a few sentences from him in an old perfume book, and they were completely revelatory! This is great - thanks for doing this.
Your PDFs were fine. You can probably get away with smaller files at lower image resolutions (especially on the 48-pager) without too much loss of image quality. I would try to keep them below 4-5 MB if at all possible - otherwise they're very difficult to mail or download over a bad connection. It's OK to experiment - that's what even a geek would do.
I'll come back after reading. In the meanwhile, please thank Michel for his generosity in sharing this material!
