It was founded in London, in 2002 by former St Austin Press editor Ashley Paver and other young Catholics who had previously worked in publishing and printing.
[1] The original objective of Baronius Press was to raise the quality of traditional Catholic books in order to make them more appealing to a wider audience.
Baronius Press aimed to achieve this goal by retypesetting classic Catholic books (rather than republishing facsimiles) and binding them using high quality coverings such as leather.
In 2004, Baronius Press published a new 1962 missal in cooperation with the Priestly Fraternity of St. Peter, bearing an imprimatur from Bishop Fabian Wendelin Bruskewitz, for use at the traditional Roman mass.
On 29 September 2016, Baronius filed a civil lawsuit against TAN Books, a North Carolina–based Catholic publisher, and its parent company, Saint Benedict Press.
TAN elected to reprint again Fundamentals in 2013 in hardcover, prompting Baronius to file suit against Saint Benedict Press for copyright violation.
