“One of the most important classes of Search Books is those included in the category of Annotations. They are important and valuable, in that they often purport to give, in very condensed form, some indication of the law, deduced from the cases or statutes, as well as to point out where similar cases can be found.” William M. Lile et al., Brief Making and the Use of Law Books 84 (3d ed. 1914).
