I want to know the answer to the following question:
Which book of literature standards suggests capitalizing the first word and all nouns, pronouns, adjectives, verbs, and adverbs?
All the background I'm provided with is that "As regards publication titles it is, however, a common typographic practice among both British and U.S. publishers to capitalise significant words (and in the United States, this is often applied to headings, too).". Is that enough to answer the question?
Answer: no
