The correspondence of the brothers Pez comprises some 1150 letters from the years 1709–1763, held at the Abbey of Melk and in numerous other archives and libraries throughout Europe. The first two volumes, corresponding to about half the preserved letters, have been published:
Volume I (2010): 1709–1715 Open Access
On the basis of the already finished preliminary transcriptions and commentaries, the remaining volumes for the period 1719–1763 will be completed within the project "Benedictines, Church Reform, and the State in Austria, 1720–1740" (2016–2018). Simultaneously, the edition will be converted into a fully digital format and combined with the digital Pez papers in a virtual research environment.
