I was assuming that is what you would say but wanted to make sure. When you write scientific papers you often do both, a direct quote with an attribution and then a hard reference to a published work. But beware the unverifiable personal communication.
Nobody minds being quoted as in attributable text. What we don't like is to read something that sounds very familiar only to realise later that we wrote it!
If I Google my name, I find masses of material of mine that has been taken from its original source and translated into many different languages - usually Eastern European or Chinese. I might not get paid but at least it's attributed, which is how it comes up on the search. How much stuff is not, I wonder?
It's also quite strange to find myself reviewing a book that is well written but know that the authors started out on their careers by cut & pasting my stuff!
I know of one successful professional who started off by showing the work of a now venerated British film-maker/underwater photographer as his own. No names, no pack drill but older Brits might know who I mean.
