Macquarie Dictionary - PE1625 .M26 2005
"Since its first publication, in 1981, it has been progressively adopted by Australian schools, businesses and courts as their standard dictionary. The second edition was published in 1991 and it introduced encyclopedic content to many entries. The third edition, published in 1997, made use of an inhouse corpus of Australian writing, Ozcorp, to add a large number of examples of Australian usage, in a style reminiscent of the original Oxford English Dictionary. The fourth edition, published in 2005, increases the number of citations, includes etymologies for many phrases and pays particular attention to Australian regionalisms (Wikipedia)."
