As an academic, my papers (I assume) have been cited. But only once do I remember a publisher, on behalf of a writer, contacted me to ask if they could reused (or republish) a chart I had created in one of papers - for a textbook. I gave them my permission and that was the end of it.
Now I am about to publish my first (non academic) book. I still have footnotes with citations, maybe 5-10 per chapter, but it never occurred to me to ask permission, as long as the citation was proper. The only time I asked for permission was when I printed a comic strip by a popular author.
So - for the other citations - do I need to get permission to publish a quote, or a small excerpt? (for instance if a sentence with an industry fact or statistic).
Clarification: I am asking about both citations (paraphrased in my own words) ... but especially quoted material.
Three examples:let's say an author wrote a book about blogging.
- In the first case his book is organized into 10 chapters, each with a title that colorfully describes his tenets of blogging. In my book, write:
Famous blogger Joe Smith, in his book "Blogging for Fame and Fortune" writes the 10 tenets of blogging: (list follows)
- Same example, except that, instead of chapter titles, inside the book, the author has the tenets listed explicitly. In my book. I write something similar, quoting the list.
- Same example - except in my book, I only quote or cite 3-4 elements of the list.
Which, of any of those do I need to get the other writer's permission (or his publisher's permission)? Or is justy proper attribution OK?
