If I paraphrase a short excerpt from a book and identify the author and book in the paraphrase, do I need to receive permission from the author to publish his material? The book is 280 pages and the quote is approx 343 words.
Such a quote from a 280 page book would not give rise to a valid copyright infringement
The four factors judges consider are:
(a) the purpose and character of your use
Purposes such as scholarship, research, or education may also qualify as transformative uses because the work is the subject of review or commentary.
It Appears your book is "educational" in nature and you
add value to the original by creating new information, new insights, and understandings.
This factor leans toward fair use.
(b) the nature of the copyrighted work
You are using the quote in a commercial activity but, should your work prove successful, such quote alone would not be the likely cause. Restated, you are not relying on the "good will" associated with that quote to make money.
Also, authors enjoy the right to be the first to publish their work. If you somehow obtained this quote before the book was published, you might have a problem.
Since the book has already been published, not problem here.
At worse the factor is NEUTRAL
(c) the amount and substantiality of the portion taken, and
Clearly a 300 word quote from a 280 page is de minimus, UNLESS, one can reasonably contend those 300 words are the "Heart of the work". I do not see that being the case.
This factor leans heavily toward fair use.
(d) the effect of the use upon the potential market.
You act of quoting from that book is very unlikely to hurt the market for such book - you may even help the market for such book.
Leans toward fair use.
Based on the above, it is safe to conclude your quote would be protected by the fair use exemption to copyright infringement.
Also, what are the international laws about this. The book is being published in Australia and will be distributed worldwide. The excerpt is from a book published in USA.
The Berne Convention treaty is likely the controlling international authority.
Under the Berne Convention Treaty, the law of the country where a work is published is the controlling law. When you publish a work in the USA, USA copyright law applies. When you publish the same work in Australia, Australian copyright law applies.
