In the following classified list the standard books are collected which may properly be consulted as bearing on the general subject-matter of constitutional law or history. The date of the first publication is usually given, but the number and date of the last edition, if there has been more than one, is not specially indicated, unless it is deemed important. Some works of a general character are here mentioned which are not cited in the chapter references. Monographs and articles in periodicals cited in the chapter references as furnishing interesting discussions on special topics are not included in this list, but are sufficiently described in the references under the chapter headings.
