Both copies of the DIA report are now indexed by Google.
1. http://newenergytimes.com/v2/news/2009/2009DIA-08-0911-003.pdf
2. http://www.lenr-canr.org/acrobat/BarnhartBtechnology.pdf
Number 1 is in the original image-only format as released by the DIA.
But Google still finds text in it. I did a search for:
"Worldwide Research on Low-Energy Nuclear Reactions Increasing and
Gaining Acceptance"
With and without quotes, Google found both documents, and listed them
at the top of the page.
This confirms that Google does its own in-house OCR of image-only
documents. However, I think it is a good idea to convert image-only
files to image-over-text or text format, because that way I am in
control of the OCR and I can correct mistakes.
(As it happens, I am not in control of the OCR with the DIA document,
because I could not make corrections. The reasons are beyond the
scope of the discussion. Anyway, you can see the OCR errors in my
version of this document by copying and pasting sections of it. For
example, the first paragraph says: ". . . nuclear activity and
transmutation of ekments" instead of ". . . elements.")
