The West Virginia University library has just received a collection of letters as a gift from Dr. Harold N. Moldenke, Director of the Trailside Nature and Science Center at Mountainside, New Jersey, oldtime friend, classmate and colleague of Earl L. Core. These letters are a selection from his personal files of correspondence with scientific workers in all parts of the world over the past forty years, selected with a view of preserving the authentic signatures of these distinguished scientists, and, wherever possible, also a sample of their normal handwriting. This collection will be of considerable value to students of cheirography in years to come, as well as to biologists and historians of the future as a typical cross-section of the botanists, zoologists, and other natural scientists who were most active in the 1922 to 1962 period of history. There are some 1300 letters in the collection, from 1175 scientists of 69 countries.
