Rider also published a Basic Audio series by Norman H. Crowhurst, a prolific electronics author who later lived in Oregon. Volume 2, published in 1959, is nearly identical in style and size to the navy material; even the illustrations look like they came from the navy. Both BJTs and electron tubes appear in the 122-page book. While the content is not quite at an engineering level, it is hardly vacuous and makes for interesting perusal by engineers.
In 1962, Howard Sams (by then a Bobbs-Merrill company) published a "basic electronics series" on Transistor Circuits and also on Radio Circuits, both by a navy captain, Thomas M. Adams. Previous basic circuits books by him were based on electron tubes. These books did not have the navy style; they had more text than drawings, though the current flows on circuit diagrams were in color and were solid or dotted, to aid explanation. (See page 114 below, as an example, using the negative-current convention of the US Navy.) Although these books are also best suited for technicians, they are excellent examples of how to explain concepts clearly and simply, using good illustrations. Engineering authors could benefit from a perusal of these books when writing on electronics.
