Should you receive royalties on derivative products?

Q: “Should I receive royalties on products such as Vango Notes and other derivative products?”

“I have a business textbook with Pearson/Prentice-Hall. I picked Pearson for this book because I really like the level of development they invest in new projects, and now that we are in the second edition, the book is doing reasonably well. With the second edition Pearson also launched a VangoNotes version of our book. This is how the Vango site describes them:

‘VangoNotes are exclusively for Pearson Education textbooks. Some VangoNotes subject texts may still be helpful, so browse by subject at Alternatively, your professor may be able to recommend a Pearson textbook that will be relevant for your class.’

I’ve listened to the material on my book and it could be a substitute for it (though in brief), and the quote above clearly suggests that Pearson/Vango view the resources as interchangeable. I don’t receive royalties on VangoNotes, even though it is essentially a summary version of the book, by chapter. Does anyone have some guidance for me as to what steps I should/could take to remedy this? I have talked with another Pearson author who has the same experience and concern. I also have experience with another publisher, Flat World Knowledge, which pays me a royalty on all derivative products related to my book, even study aids. My sense is that this is coming from the legal side of Pearson, not the editorial side, and I like working with my current editor.” [Read more…]
