“A Guide to Australian Monitors in Captivity” by Danny Brown— (Book) Published in 2012 and now out of print in every format except eBook, this has become something of a collector’s item for monitor keepers. It offers excellent advice on every facet of husbandry specific to Australian monitors, detailing what sets them apart from monitors from other parts of the world.

“Monitor Lizards: Natural History, Captive Care & Breeding” by Bernd Eidenmuller— (Book) This is published by Edition Chimaira, so you know it’s good. Thin enough to be digestible, thick enough to offer excellent insights into a variety of monitors including ackies.

“Reptiles & Amphibians of Australia, Updated Seventh Edition” by Harold G. Cogger — (Book) This is one hefty field guide, packed with detailed information on all Australian reptile and amphibian species described prior to October 2013 — including ackie monitors. Field guides are an invaluable resource for gathering the natural history information necessary to great reptile husbandry.
