The Society's manuscript holdings at that time were estimated to be 2,500,000 items, contained in 1,141 listed collections. Within the last decade, these holdings have increased approximately 60%, so that now some 4,000,000 items are to be found in 1,609 collec- tions. Furthermore, whereas in 1940 only 30% of the manuscripts were arranged for ready use by students, today 98% are so arranged. During the past ten years, we have also made every effort to improve the manuscript catalogue which has grown from 200,000 to 500,000 cards. In spite of this tremendous increase, the number of items covered by each card has been reduced from 12.5 in 1940 to 8.0 at present. This represents real progress, but much work remains to be done. Excluding our holdings of foreign manuscripts, which number some 200,000 items of considerable importance, our collections deal primarily with Philadelphia and Pennsylvania.
