I'd be quite interested in owning a copy of "Modern Instrumentation Tape
Recording - An Engineering Handbook", but not 48 of them:

Remember that "instrumentation" recording is significantly different
than the kind of audio recording that is within the charter of this
newsgroup. Depending on your depth of experience and knowledge,
and what you are seeking to learn, this book may not be a very good
choice. (even if you could get just one).

Amazon lists five copies availble at prices ranging from 5-20 USD.

Instrumentation/logging recording is likely annother field that has
been completely taken over by digital methods.
