Do I need permission to reproduce text quotations from other sources?
It is the custom and practice in academic publishing that short extracts of text may be reproduced without formal permission, on the basis that:
the purpose of quotation is objective and evidenced scholarly criticism;
the quotation is reproduced accurately, either within quotation (“ ”) marks or as displayed (indented) text;
full attribution is given.
As an author, you are required to secure permission to reproduce any proprietary material, including text, where the above exceptions do not apply (e.g. for illustrative purposes, a poem or song in full).
