Practical Guide for the Householder & Air-Raid Warden - S. Evelyn Thomas

One of the very best overviews of Air Raid Precautions and how the various organisations within Civil Defence were run can be found in Samuel Evelyn Thomas's Practical Guide for the Householder & Air-Raid Warden (first printed in 1939 by James Askew & Son). The 90-page booklet is quite detailed with several illustrations (it also re-used colour copies of the ARP cigarette cards). It is a great reference for how the Wardens' Service was set up and run. It also gives a great run-through of how the various first aid groups were set up and run in towns and rural areas. 

The copy below is an original Fifth Edition (400th thousand) and goes to show how many were printed. Currently, I've seen editions with the eighth edition on the cover.

Evelyn Thomas was a Group Warden from St. Albans and a prolific writer who wrote articles that appeared in many of the ARP / Civil Defence magazines of the day. He also published a guide to the Civil Defence Act of 1939, a rare booklet called the "Handy War-Time Guide", "Tactical Training in A.R.P.", as well as "Incident Cards", a training resource for incident officers.

Well worth finding a copy and reproductions printed by the IWM are also available but contain only 32 pages.
