How to Impress Even the Most Exacting Bluebooker[H]ere is a list of some of the more obscure Bluebook rules. As their presence on this list indicates, these rules are hard to find, ometimes only by actually leafing through and scanning the Bluebook. Furthermore, these rules are not necessarily intuitive—after all, why, for example, do prepositions with five letters have to be capitalized in headings, but not those with only four? However, errors in the application of these (and other) Bluebook rules are apparent to experienced Bluebookers such as editors, judges and their law clerks, and law firm recruiters and partners. Thus, it may be worthwhile to familiarize yourself with—and, if necessary, simply memorize—some of these rules.*
