I have a number of pieces in my collection published by Prayer Book Press. Their material that I’m aware of seems to be Conservative, but not USCJ, which seems like an odd distinction, but there it is. I say this because it looks like that’s the tone of the content and because at least one of their works that I have was edited by Morris Silverman.
I just googled PBP. They’re located in Bridgeport, CT, it seems. Other than that, there’s nothing about them on the web except for their siddurim and machzorim. They have apparently on web presence. Does anyone know anything about them? Do they still exist?
