These books form most of the U of G Archives collection of the No. 4 Wireless School Reference Library.   Several of them are from the Royal Air Force or Royal Canadian Navy.    Most are about electricity, electrical apparatus, radio antennae, telegraphy, and radio direction finding (not radar).   There are no books here about "Radar", which was <i>top secret</i> in 1941.<br><br>Books courtesy of the University of Guelph, McLauglin Library, Archives and Special Collections.
