There are three situations where you can copy without limit.
5.1 Copying for the purpose of examinations.
Any amount can be copied for the purpose of setting examination questions, communicating the questions to the candidates or answering the questions.
5.2. Copying where the work is unavailable
You may copy any amount of a work (other than articles in periodical publications) for a course of education conducted by SP if you have carried out a reasonable investigation and you cannot obtain the work within a reasonable time at an ordinary commercial price. This may put you under the fair dealing defence. If you are in doubt as to whether you fall under this exception please contact the corporate lawyers.
Please retain the evidence of the investigations you made. The evidence should be filed as soon as possible in a file marked "Copyright - Commercially Unavailable Works Record" to be maintained by the Quality Assurance Manager of the respective schools/departments. The records have to be retained for 6 years.
5.3 Copying by a non-reprographic process (i.e. by hand)
You may copy any amount of a work for the purpose of a course of education provided
A. You are the one conducting or undergoing the course of education; and
B. The copying is by means of a non-reprographic process.
"Reprographic process" means a process for making facsimile copies, or involving the use of an appliance for making multiple copies, e.g. a photocopying machine. It includes any copying by electronic means as well.
Non-reprographic is therefore interpreted to mean by hand.
