Creating a book based on an article (copyright issues) I've asked this question at math.stackexchange.com, but a comment proposed me to ask this question at  academia.stackexchange.com instead.

Here is my question:

Elsevier explicitly permits me to make a book based on my article published with Elsevier.

What's about other publishers? May these forbid me to make a book based on my earlier article?
If you need to publish the book and you have found one publisher that allows it.

Why do you seek more?

Elaborate what is wrong about Elsevier that makes you not to pursue it with them?
