Reasonable Time and Commercial Price
See also: Unpublished works, Separately published, Out of print works
Reasonable Time and Commercial Price is the standard used in the Copyright Act to determine whether or not more than 10% or 1 chapter of a literary, musical, dramatic or artistic work can be copied for educational purposes or under Fair Dealing for the purpose of research & study.. If the work is not available at a "reasonable time and normal commercial price" then more than 1 chapter or 10 % can be copied.
The Copyright Act does not specifically define either reasonable time or commercial price. Copyright Agency Limited (CAL) has indicated that a reasonable or 'normal' commercial price is what you would be asked to pay for the item from a book seller if it was new. CAL has also indicated this means you do not have to buy the leather-bound edition if available or second-hand copies. CAL advises that for textbooks a 'reasonable time' is six months; for other types of works CAL regards 30 days as a 'reasonable time'.
