Books of authority is a term used by legal writers to refer to a number of early legal textbooks that are excepted from the rule that textbooks (and all books other than statute or law report) are not treated as authorities by the courts of England and Wales and other common law jurisdictions.

These books are treated by the courts as authoritative statements of the law as it was at the time at which they were written, on the authority of their authors alone. Consequently, they are treated as authoritative statements of the law as it is at the present time, unless it is shown that the law has changed, and may be cited and relied on in court as such.

The statements made in these books are presumed to be evidence of judicial decisions which are no longer extant. The primary reason for this practice is the difficulty associated with ascertaining the law of the medieval and early modern periods.
