About this Collection

Twentieth-Century Legal Treatises


Nineteenth-Century Legal Treatises, which allows the researcher to trace the evolution of modern law in the United Kingdom, as well as in the United States, concluded with the publication of unit 69. In all, over 14,000 titles were filmed from the holdings of the law libraries at Harvard, Yale, Columbia, and York universities.

Twentieth-Century Legal Treatises contains works on the subject of law printed in the United States and the United Kingdom during the twentieth century. The scope of this collection will allow the researcher to continue to trace evolving modern law into the 20th century--an important development for Anglo-American legal scholarship. The legal treatise tradition of the 19th century continued into the first decades of the new century and access to these materials in their original form has become increasingly difficult for modern scholars. The deterioration of book paper and heavy use over many years has literally destroyed or rendered most of the remaining copies unusable. The microfiche edition will assure the preservation of these valuable and elusive publications.

The Twentieth-Century Legal Treatises collection consists of titles on a 49-frame positive microfiche, with a ratio of 24x. This film, employing a silver halide emulsion, meets all industry standards for archival permanence. The microfiche heading has been designed to industry standards. The eye-legible, abbreviated title of each work is centered on the top line of the Document Description Area, with the author and imprint date appearing directly beneath. The information contained in the right-hand field of the heading, the Sequential Information Area, offers identification unique to the work: the sequential fiche number for the entire collection, the number of fiche cards corresponding to that title, the sequential card number for the title, and the range of pages filmed on the card. The Identification Area is left blank for local library information.

The first row of each fiche card contains the bibliographic and source information as well as a three-part identification number. This alphanumeric target consists of the following: a US or UK designation, the numerical subject category of the item assigned by the Harvard Law School Library, and the sequential number within each category. The subject categories range from 01 to 99 and each signifies one of the classification codes assigned by the Harvard University Law School Library. A numerical listing of the subject categories appears in the appendix of this guide. For example, US/92/8 indicates that the item has a United States imprint, is classified under category 92, or Equity according to the appendix, and is the eighth item filmed in that subject category.
