Another "couple" of books are from Richard Graves.
The "10 Bushcraft Handbooks" are still very popular and seem widely available on the internet.They were first published in 1952.
Bush Ropemaking,
Bush Hutmaking,
Snares and Traps,
Impoverished Campcraft,
Time and Direction,
Travel and Gear,
Food and Water in the Bush,
Firemaking,
Tracks and Lures and
Knots and Lashings.
Lesser known is his 1944 book "Bushcraft; How to Live in Jungle and Bush" also by Richard Graves, but written with the pseudonym
"Wontolla" to protect his identity (during WW2).
There is a very good write up on Richard here:
