There is a good book on tape editing by Joel Tall.

Subject: [ARSCLIST] the birth of the ATR-100, tape-path tension, tape
editing from the aces at CBS Radio, etc
(remember to paste complete link into your browser)

Some scans from dB Magazine, including a 2-parter on the development of the
Ampex ATR-100, and a primer on tape editing tricks from one of the
old-school aces at CBS Radio.

Note that the Ampex 350/Lang editing carts shown in the CBS Radio photos
ended up being part of one of the best dumpster dives in NYC history, when
CBS dumped them all in the early 90's. I don't know this for a fact, but I
suspect Lang developed those editing carts for CBS Radio and then sold them
to others. They were shown in Lang literature from the mid-60's. The carts
contained a JBL or Jensen full-range speaker in the door, powered by a
Langevin 10W tube amplifier. I think some of the carts had Lang electronics
inside, some used Ampex 351 electronics with the VU meter and some controls
moved up to the panel behind the transport. The units I saw from the
dumpster dive were in very rough shape, but the Langevin power amps,
full-range speakers and parts from the tape electronics made for good eBay
fodder. The rollarounds are rock-solid. I still have one.

Also of interest is the followup to the CBS Radio article, from a former
audio man there. The story of Joel Tall inventing the editing block is
recounted. I have previously posted a scan of the liner notes of the
original 12" 78 multi-disk album of Edward R. Murrow's first "I Can Hear It
Now," which discussed using the great "new" medium of magnetic tape to
produce the recording, with Joel Tall being one of the mentioned editors.
Joel Tall of course patented, developed and sold the EdiTall splicing block.

As for the cover photo (the single JPG file), here's the caption (obviously
meant somewhat tongue in
"Chief Engineer Kurt Munkacsi of New York's Big Apple Recording Studio must
sometimes resort to extremely drastic means to adjust torque on his
machines. He can be seen in more normal pose on the cover of John Woram's
"The Recording Studio Handbook." Photo is by Ray Buchner."
