It has been nearly 50 years since the publication of the original <i>Plan</i> and <i>Bibliography</i> (1954) by Hans Kurath (<i>Plan</i>) and his colleagues Margaret S. Ogden, Charles E. Palmer, and Richard L. McKelvey (<i>Bibliography</i>). This new edition of the Plan is a complete reshaping and rewriting of Kurath's original, with an up-to-date history of the project and a comprehensive guide to the entries and their constituent parts. The <i>Bibliography </i>contains all of the items used in the print dictionary, combining the original <i>Bibliography</i>, the supplement published in 1985, and the additions made between 1985 and 2001, when the last fascicle was published, and amounts to some 5,400 items, including over twenty-five percent again as many as in the original, with notes on date and title changes and where they occurred in the dictionary.<br>
