Umm. Have you ever googled for something and had
it turn up PDF
files? I'd say fully a third of them that I run across contain
images of pages, not text.
How do you know it doesn't contain text? As described earlier in this
thread, the PDF file can be constructed with a "hidden" text layer
that is OCR'ed from the images so that text searches work. I bet that
Google just searches embedded text because they never find stuff on
bitsavers when you search for text.
