Schultz was also on good terms with many prominent writers, including Knud Lyne Rahbæk, C. Pram, T. Thaarup, R. Nyerup and Jens Baggesen.

Among his most notable publications was an edition of Ludvig Holberg's Niels Klim in Baggesen's translation from 1789 with illustrations by Nicolai Abildgaard.

He immediately acquired a publishing house in Skindergade from P. M. Høpfner, who was both responsible for publications from University of Copenhagen and the Court.

Schultz moved his business back to Højbro Plads when a new building had been completed in 1797 and it soon developed into one of the largest Danish publishing houses om Copenhagen.

Among Schultz's most important publications from this period was Rahbek's edition of Holberg's complete works which was published in 21 volumes between 1804 and 1814.
