The collection of Bernard Free Library was increased by the publications in various subjects from west countries which were added by Sir John Jardine and Professor Childers from the Pali Department of Yangon University. U Po Hmyin and U Myo from Yangon also donated palm-leaf manuscripts and parabeik, and books in Mon, Myanmar and Pali languages for value of 10000 kyats of that period.
