There are four different types of texts which Liberty Fund has made available as part of the Online Library of Liberty website:
For titles in the first three categories listed above, no special permission from Liberty Fund is required for quoting material in papers and essays, or for limited photocopying and distribution for academic or other educational or non-profit purposes. The only requirements are that you include proper attribution on the first page of the document being distributed - e.g. for John Locke’s The Two Treatises of Government you would say one of the following:
For titles in category two and three, any reprint of material “for profit”, such as a chapter or a substantial section of an online book for inclusion in a book or other publication for sale, requires written permission from Liberty Fund.
For titles in the fourth category you must follow the specific requirements of the copyright holder whose work we publish online under license. This information can be found in the “Introduction to the Book” page under the section “Copyright Information.” In the case of the Collected Works of John Stuart Mill published under license from the University of Toronto Press, for reprint or copying permission you need to contact UTP directly. Under our contractual obligations with UTP we have placed the following declaration on the front page of every book and section of the online version of the Collected Works of John Stuart Mill:
The online edition of the Collected Works is published under licence from the copyright holder, The University of Toronto Press. ©2006 The University of Toronto Press. All rights reserved. No part of this material may be reproduced in any form or medium without the permission of The University of Toronto Press.
Thus, for reprint or copying permission you need to contact UTP directly. Liberty Fund cannot grant you this permission because it is not the copyright holder.
