Most recovery techniques rely on reducing the manuals moisture to a certain level and maintaining it there and the the best way I heard was to take to a facility that can freeze dry and vacumn dry in parallel. The contents of the Los Angeles public library was nearly destroyed but for using old aerospace facilities around the area to put large quantities of books into old vacumn test chambers with liquid nitrogen cooling, and some mods to the vacumn systems to tolerate the extraction of the moisture. Most computer manuals are printed on paper that shoulc be recoverable, since it basically is high rag based paper, w/o any applied coatings. The sort of papers used by magazines use either plactic coatings, or a very fine clay coating with treatment over paper to get the "slick" look, and those were nearly impossible to recover. (unless new techniques were developed since I last read, anyway). I don't know if you can do this with any resources you have, or know of, but the vacumn / freeze dry method is the best I have heard of. Of course be sure to pack it to guard against mildew and rot, or you won't have anything worth restoring either. Jim
