I have been invited to submit a book chapter. The invitation email says:
Due to your involvement in the field, and the research you published in your paper, 'X', publisher 'Y' invites you to extend your work and offer a more comprehensive overview of your studies. Contribute a chapter to 'Z', an upcoming Open Access book edited by Dr.'W'.
Surprisingly, paper 'X' is completely unrelated to the Book 'Z'. The book is edited by a renowned professor, the publisher is InTechOpen.
What to do in such case? Can I select any of my published papers in journal for this purpose? Will it not create any copyright problems?
