Contemporary Hagiography
Jerome included brief mention of Pope Damasus in his De viris illustribus.
You can also read the Life of Pope Damasus in the Liber pontificalis. The lives, however, were not contemporary at this date, but were surely using earlier sources.
Writings by and to Damasus
Damasus wrote many epigrams. Here they are in Latin. They have recently been translated into English, and although not in the public domain for many years, you can actually see quite a bit of it in the Amazon preview.
Here is an epitaph that Damasus wrote for her sister. It is here only in Latin, but with some translation helps. Damasus wrote a hymn to Saint Agatha, here in English, which can also be read on her Feast Day, and a hymn to Andrew.
Jerome served as his papal secretary and you can read this letter from Jerome to Damasus. Jerome also addressed his preface to his translation of the Gospels into Latin (the Vulgate) to Pope Damasus.
Damasus presided over the Council of Rome in 382 which issued the Canon of Sacred Scripture, also know as the Decree of Damasus, listing the books agreed upon as Scripture. Here it is in extended form, as the Decretum Gelasianum in 492.
