You can scan them with OCR software, but if you want the results to be
accurate, you have to carefully edit the results, which is what I've
done with a number of documents and reports (and in one case a
complete book) at my site. It's a pain in the tuchas, but I have some
proofreading and editing experience, so it's not a big deal for me. It
may not be feasible when you're dealing with the volume of documents
that the Weisberg Archive contains.
Not to mention that, in the case of Weisberg's own voluminous
correspondence, you're dealing with a guy who insisted upon doing
everything with a beat-up, old typewriter, with all kinds of
misaligned characters, typos, misspellings, cross-outs, and
handwritten corrections: truly an OCR nightmare! (The personal
computer was not for him. Around 1997 or '98, I sent him an index I'd
created for his book OSWALD IN NEW ORLEANS -- I was a rabid conspiracy
theorist at the time and thought OINO was a REALLY IMPORTANT BOOK --
and a floppy disk with the file in various formats. When it came to
the computer stuff, he told me, it was all Greek to him, the
difference being that at least when it came to the Greek language,
there were a few words he could recognize here and there.)
I only had just a very few written and telephone exchanges with him,
and they weren't always pleasant (I think Walt Brown once said
something about how getting a tongue-lashing from Harold was all a
part of "earning one's wings" as a researcher), but, even as much as I
have come to disagree with him about so much, it's hard not to miss
that cantankerous, obstinate man who fought hard and sacrificed much
to wrench documents from the grasping hands of bureaucrats and share
his findings with anyone who asked.
