Thanks, Gents,
But according to one smallish pdf file that I send to a web based
tool, it was not a real pdf. Or, more accurately, it (the pdf to
speech program) couldn't decode it. I'll play around with this
more tomorrow. The problem with a lot of this electronic paper
is that the lines are sequeezed together. Makes scanning them
that much more difficult. Last month I read a book [book-book,
from the library!] with more ~1.5 spaces between lines, and even
tho the font was small, no problem in reading the entire text.
((FWIW: I'll find the URL of a piece on Hegelian ethics --PDF--
and see if the firefox speech site can grok that!))
