Thanks, I am using Book because I am running SWeave, which currenly Lyx only supports in Book,Report and Article. I believe this is changing in Lyx 2.0, but for now I am stuck with Book. anonchap works fine for the text, but it still leaves Chapter 1, Chapter 2 etc in the header. I have had a look at the documenation for anonchap and tocbibind and I can't see anything obvious to fix the header. Can you suggest an approach for the header. Thanks again, Graham
