Edward James Nolan, A Short History of the Academy of Natural Sciences of Philadelphia (1909)
“ The several series of the publications form 151 volumes. The output for the year 1908 amounted to 1,936 pages and 133 plates. It is gratifying to know that the quantity of the matter published is in no sense at the expense of its quality. The importance of the Academy is measurably dependent on the discoveries announced in its publications. They are the organs of speech of the society by means of which it holds communication with naturalists in all civilized countries. They encourage the student to labor, for investigation would be purposeless if the results could not be given to the world. ”
