What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

Some of my posted answers to questions of using pyparsing are very detailed, and at some time in the future, I would like reuse some of them as material in a copyrighted ebook or book. Can I do this, given that posts on SO are under the CC-wiki license? And can someone else do this with my answers, publish my answers in their publication?

Standard I am not a lawyer; this is not legal advice disclaimer applies.

When you write your posts, you hold the copyright. As such, you have final control over who can publish the material. When you post them on the Stack Exchange network, you grant a non-exclusive perpetual CC-BY-SA license to Stack Exchange. What this means is that anyone can reuse and modify your material's posts so long as (1) they attribute you appropriately, and (2) their work also has a CC-BY-SA license.

However, you are not bound by the CC-BY-SA license, since you are the copyright holder. Therefore, you can continue to use your work in any form you choose, including publishing them in a book.

This, however, does not stop anyone from finding the original posts on Stack Exchange and reusing them from here (following the attribution guidelines), as they have the Creative Commons license you granted when you published the material on Stack Exchange. Any new material, however, would be entirely protected since you have not granted CC-BY-SA on those.
