Thank you. I agree that they should be capitalized. Unfortunately where I had been inquiring previously, I was getting mixed responses; some yes & some no re: capitalization; some saying just the first word of the chapter title which made no sense to me whatsoever. Thanks again for your response.
Traditional rules of capitalisation are frequently ignored for stylistic reasons by authors and publishers. You'll see not only uncapitalised chapter headings but also book titles in lower-case letters.
(Incidentally, '&' doesn't look good in standard text.)
Thank you for your feedback. I'm old school and firmly believe that all titles should be capitalized. I agree, it doesn't look good in standard text. I don't think it looks good in lower case either as it just doesn't stand out like it should. Thanks again!
