Worse yet, the .pdf format requires a copy of Adobe Acrobat Reader
(admittedly
downloadable for free if you go looking) in a version equal to or newer than
the one used to create the file...and you CAN'T use "Edit, Copy" to save
the piece you were looking for, because a .pdf is just a PICTURE of
text...not text! This means you have to save the entire .pdf on your
HD, use Acrobat Reader to access it and manually copy the text you
are interested in! This is something like making sound recordings
available in a proprietary format with limited fidelity...
