in many books, when one part of the book mentions another part of the same book, or mentions the work as a whole, the name is set in small caps (sometimes typesetting small caps after transforming to title case), not italics and not roman type within quotation marks. for example, articles in "the world book encyclopedia" refer to the encyclopedia as a whole and to the encyclopedia's other articles in small caps, as in the "insurance" article's direction, at one point, to "see nᴏ-fᴀᴜʟᴛ iɴsᴜʀᴀɴᴄᴇ", "no-fault insurance" being another of the encyclopedia's articles.
