Legal History: The Year Books"More than 22,000 individual reports or ‘pleas’ have been printed, and others remain in manuscript. This database indexes all year book reports printed in the chronological series for all years between 1268 and 1535, and many of the year book reports printed only in alphabetical abridgements. Of these reports, all 6,901 from 1399 through 1535 have been fully indexed and paraphrased in this database." Compiled by David J. Seipp, Professor of Law at Boston University.
