REPORT OF THE SECRETARY 113 



They supervised the 17 W. P. A. employees assigned to the library 

 in such tasks as cleaning, repairing, and binding books, putting 

 pamphlets into binders and lettering them, renovating plates and 

 maps, typing cards, filling out acknowledgment forms, mounting 

 aeronautical clippings, sorting and filing duplicates, and assisting 

 with the cataloging. 



They effected special exchanges of duplicates with the libraries of 

 the Massachusetts Institute of Technology, Marine Biological Labora- 

 tory, Woods Hole, Staten Island Association of Arts and Sciences, 

 American Museum of Natural History, United States Patent Office, 

 and the following colleges and universities: Brown, California, 

 Catholic, Columbia, Duke, Harvard, Michigan, North Carolina, 

 Pennsylvania, Princeton, Stanford, Williams, and Yale. By these 

 transactions they placed many publications not wanted by the Insti- 

 tution where they would be useful and obtained many that were 

 needed in the collections. Among the latter were Forges and 

 Furnaces in the Province of Pennsylvania, issued by the Pennsyl- 

 vania Society of the Colonial Dames of America; The Cannon 

 Collection of Italian Paintings of the Renaissance, mostly of the 

 Veronese School, by J. Paul Richter; The African Republic of 

 Liberia and the Belgian Congo, Volume II, edited by Richard P. 

 Strong; A Guide to the History and Historic Sites of Connecticut, 

 in 2 volumes, by Florence S. M. Crofut; Practice of Tempera Paint- 

 ing, and Materials of Medieval Painting, by Daniel V. Thompson; 

 Eclipses of the Sun, third edition revised and enlarged, by S. A. 

 Mitchell ; A Catalogue of the Epstean Collection on the History and 

 Science of Photography and Its Applications Especially to the 

 Graphic Arts, by Edward Epstean; Benjamin Franklin's Own Story, 

 by Nathan G. Goodman; Roman Glass from Karanis, by Donald B. 

 Harden; Annual Review of Biochemistry, Volume VII, edited by 

 J. M. Luck and C. R. Noller; and numerous volumes and parts of 

 the Meddelelser om Gr0nland. 



The staff continued the revision of the files of society and engineer- 

 ing publications in the natural history and technological libraries of 

 the National Museum, thus making these important sets more avail- 

 able for use. The work with the latter was expedited by the arrival 

 of the steel shelving that had been ordered toward the close of 1937. 



They finished recataloging the sectional library of botany and 

 began that of administration. 



And they spent even more time than usual identifying for the 

 scientists of the Institution obscure citations found in the literature 

 of their respective subjects, and providing data, including not a few 

 bibliographies, for letters in answer to requests for information 

 received from different parts of the country.
