This year, Holy Trinity Publications participated in the 75th Annual Frankfurt Book Fair in Frankfurt, Germany. The event lasted from Wednesday, October 18 to Sunday, October 22, 2023. Holy Trinity Publications has been exhibiting at this book fair since 2014, and this was the fifth time it had its own display. 

The Frankfurt Book Fair is the world's largest and longest running trade show in the book industry. Though the modern iteration of the book fair has been running for seventy-five years, its history can be traced back all the way to the 12th century. This year, 326 agencies representing thirty-one different countries are exhibiting. In 2023, the book fair hosted a record total of 180,000 guests.

The event gave Holy Trinity Publications opportunities for face-to-face meetings with industry professionals from all over the world, and opened up exciting opportunities for wider distribution, as well as the sale of foreign-language publication rights. This year one particular topic of wide concern and discussion was the impact of artificial intelligence on the work of publishing.
