Insubstantial portions

Insubstantial portions are important because they can reproduced without needing the permission of the copyright owner. Use of an insubstantial portion is not restricted to particular purposes such as fair dealing or educational purposes. An insubstantial portion is:

However, insubstantial not only refers to the amount but also the context. You cannot copy or reproduce a portion of the work that is key or central to the work even if it is less than one per cent. For example: a well known section from a book or a chorus from a song may be less than one per cent of the overall work but it would not be considered an insubstantial portion because of its importance to the overall work.

The insubstantial portions exemption does not apply to copying or communicating:

If copying or communicating an insubstantial portions for educational purposes in addition the conditions outlined above the following applies: a period of 14 days must elapse before a person relying on this provision can copy or communicate any other part of the same work & no other part of the work may be online at the same time. Non continuous passages of the work are considered different parts, so the portion copied must be a continuous extract. If the insubstantial portion is placed online it must be registered with the Copyright Office as part of the requirements of the Statutory Licence.

If copying an insubstantial portion, the source must still be acknowledged: see Moral Rights.

Quotations

Quoting from a work is not necessarily a breach of copyright. Most quotations would be considered insubstantial portions. However, you must acknowledge the source of your quotation. (Refer to Moral Rights and Citation Styles within the University). If you are planning to quote a large part of the work, it may be more than an insubstantial portion, and you may need to get permission for the reproduction.
