A crucial hub for the forging of new contacts was the Sodalitas litteraria Augustana which was founded in 1500 by Peutinger. This Augsburg-based society aimed at bringing together fellow humanists, exchanging ideas, and putting these into practice. One of its members was Matthäus Lang von Wellenburg to whom the Liber selectarum cantionum was dedicated. A number of printers from Augsburg also belonged to the association. Among those were Grimm and Wirsung. It was probably due to both the family relationship as well as the Sodalitas which connected Peutinger to both of the printers that led him to write the epilogue for the music book.
