About Us

After decades of featherweight fluff and heavyweight heresy, Catholics are searching for substantial, reliable, and profound books to read. Os Justi Press was launched in 2016, initially for the purpose of creating handsome new editions of out-of-print classics and works of historic interest.

However, the Press soon began to be approached by scholars looking for a venue to publish their own work. Over time, we have prioritized the publication of excellent new books by formidable Catholic writers across all disciplines and fields—especially those who boldly engage with the challenges of our day.

In pursuit of that goal we have launched three major series: “Studies in Catholic Tradition,” “Theological Classics,” and “Liturgical History and Reform.” Os Justi’s catalog has now grown to over 100 titles in a wide variety of subject areas, including literature, history, linguistics, poetry, music, dogmatic theology, moral theology, Catholic Social Teaching, liturgy, devotion, and aesthetics.

Submissions

Os Justi Press is a compact organization with a limited publishing schedule. As a result, submissions are very likely to be turned down, not necessarily due to any fault in the submission but because of commitments already entered into and an inability to accommodate further titles in the schedule, which is planned out for about a year in advance. However, if, upon familiarizing yourself with our catalog, you believe you have a manuscript that would be a perfect fit for our press—particularly for one of our three series: Studies in Catholic Tradition, Studies in Liturgical History and Reform; Theological Classics (descriptions of which can be found at those links)—you may submit a proposal and manuscript. With few exceptions, Os Justi Press follows the Chicago Manual of Style. The cardinal rule for any submission is that none of the text has been generated by AI.
