Microbook, as described in 1943

Anthony Boucher in his science-fiction book from 1943, One Way Trip, writes:

There were even microbooks in the rocket, with a small pocket-model viewer; there was hardly space for a projector.

Possibly, Boucher thought of the microbook as a kind of a small electronic device.
