I don't think this depends on whether the ebook is "commercially produced" or not. It depends on the software you are using to view/copy/paste.
For example, the Reading app I use on iOS, Marvin, allows you to "Copy+" or "Textshot".
Copy+ copies the highlighted section and allows you to add placeholders to the command line. You could add things like: title, author, chapter, definitions etc. Then you can paste all that info into another app.
Textshot creates a quote of the selected text + title, author, chapter info in the form of an image which can be pasted into another app.
Since Marvin is able to do this, then the answer to your question is "yes, it is possible". The real question is does the software/device you are using support that functionality.
