Control vs. propagation 23
"Which path is right for you? It depends on your objective.
Educational content is meant to be shared and an All
Rights Reserved license is going to reduce your reach. If
you need to retain full control over your content in the
hopes of getting paid, that’s OK. But don’t pin this to
false hope. You’re not going to get paid unless you’ve built
up sufficient authority. The more you restrict your
content, the more you reduce your chances of building
authority.”

All Rights Reserved
(default)
24
“All rights reserved” is the default. 24
Option: Creative Commons
(two C’s instead of 1 C)
(www.creativecommons.org/licenses/)

“Some rights reserved” is an alternative. 25

35
You let others copy, distribute, display, and
perform your copyrighted work but for
noncommercial purposes only.
NC :: Noncommercial
36
You let others copy, distribute, display, and
perform your copyrighted work as long as
any derivative work is licensed under the
same license.
SA :: Share Alike
37
You let others copy, distribute, and display

NonCommercial-ShareAlike 3.0 Unported License. This license
is available at creativecommons.org/licenses/ by-nc-sa/3.0/.
You can see what the author considers commercial and
non-commercial uses of this material as well as license

29 - 31 contain excerpts from the copyright detail.
Custom license example 40
“ • If you are printing a limited number of copies of all or part of
this book for use in a course (e.g. like a coursepack), then you
are granted CC-BY license to these materials for that purpose.
• If you are a teacher at a university and you translate this book
into a language other than English and teach using the
translated book, then you can contact me and I will granted you
a CC-BY-SA license to these materials with respect to the
publication of your translation. In particular you will be permitted
to sell the resulting translated book commercially.
If you are intending to translate the book, you may want to
contact me so we can make sure that you have all of the
related course materials so you can translate them as well.”
Custom license example 41
“Of course, you are welcome to contact me and ask for
permission if these clauses are not sufficient. In all cases,
permission to reuse and remix this material will be granted as
long as there is clear added value or benefit to students or
teachers that will accrue as a result of the new work.”
How can you simply integrate
open licenses into your work?
42
1. License your own work.
2. Use openly licensed works.
3. Attribute authors of the works
from step 2.
4. Share your work publicly
online.
