Please remember that, in general, a general permission to copy is NOT a waiver
of copyright. So those manuals for which there is a permission to copy ARE
still under copyright (assuming they were in the first place, which is likely).
What you have there is a specific permission granted by the owner (the
copyright holder), which allows you to do the things granted, but doesn't allow
you to do other things. For example, there may be permission to copy and
distribute the document as it stands; that permission may (or may not) include
permission to OCR it and distributed the resulting text in different forms.
But it may very well disallow creating derived works.
On the other hand, if an owner did indeed release a work to the public domain,
then you can do anything you want with that work.
This may not matter very much in practice, but if you want to apply copyright
correctly, you'll want to be careful to use terms like "public domain" and
"still under copyright" accurately.
