Israel SciFi and Fantasy Book Club discussion

I had posted this question to one of my fantasy groups here but didn't get a response so maybe someone here as an answer for me.

So I've been reading a new epic fantasy anthology which I've really been enjoying and I've been particularly looking forward to reading the stories by Patrick Rothfuss and Brandon Sanderson, whose names on the book's author list is what really pushed me to read this book.

But then I got to Ruthfuss's story and it turned out to just be an excerpt from The Wise Man's Fear. Disappointed, I moved onto the story by Sanderson, and that too turned out to be an excerpt from the Way of Kings. Now I'm wondering if all of, or a majority, of the stories in this book are not original, after all, but just excerpts. It's hard for me to tell since I haven't read every book by every author in it, but if this is the case it would certainly lower my estimation of the anthology.

So my question is, for those of you that read a lot of fantasy anthologies, is if this is a common practice to include previously published excerpts from an author's other books in fantasy anthologies? I noticed that in UF anthologies most of the stories are related to the authors' main series, which doesn't thrill me, but at least those stories are original.

One question- what is the book name? I am aware of such a book that contains a story of Ruthfuss and one story of Sanderson about Wheel of Time, but not of Way of kings

That sounds like cheating to me. I haven't read anthologies for a long time, I don't like the uneven feel from so many different authors, but reading an excerpt feels like promotional material rather than a book I would pay good money for.

Eyalg: It's called Epic: Legends of Fantasy and I had been really excited about reading it because includes stories by many top fantasy authors like George R. R. Martin, Ursula K. Le Guin, Robin Hobb, Orson Scott Card, Tad Williams and, as I mentioned, Sanderson and Rothfuss.

And the excerpt from the Way of Kings was of one of the short intervals included between the main story lines.

Well that's one of the issues that I have with UF anthologies, they make me feel like I'm being manipulated into reading the authors' other books by making all of the stories involving characters from those books. In this case I got the sense that the publisher included excerpts from books by big-name authors to drive book sales, which is also really wrong, though since I haven't read every book by every author in it I can't tell if this is really the case or if Sanderson and Rothfuss were the exception, and this really annoys me. But I'm sure it would bother me even more if I had actually bought this book rather than having received it to review.

I think this is the generally with the collection of anthologies, there is a new collection that I heard about, that 16 out of 23 stories are related to earlier books.
