They are! Alas, the first one I tried showed my some of the irritating
problems that get in the way of using such files as reliable scans of
original pages.

I tried various pdf software. The pages seem to be 'patchwork quilt'
reconstructions. This means it is almost impossible to know what rendering
dpi (if any!) would give a result which had no added degrading due to
rendering. And also gives no clue if the 'processing' done to clean up the
scan for getting a 'better' pdf by the creator has actually altered any
real details.

I realise some rendering / processing software does this to try and cut
down file size and 'look better'. But for archival/research purposes it
undermines confidence.

However the content is certainly interesting. And tends to look better
than
the examples on the americanradiohistory site.

I picked one at random (Micro-controlled radio-code clock) and thought he
has done an excellent job for most interested parties. Scan looks good and
even has accurate OCR of the text I checked.
