Without trawling on wikepedia I think you will find it was always a York newspaper publication, and it had a sister rag called the Yorkshire Gazette. They had a printing works right on the river Ouse in York, which is still in existence, albeit as two bars and a cinema. The building still sports The Yorkshire Herald cast into the river frontage copings. It subsequently became The Yorkshire Evening Press and is now known as just The Press and swopped over to being a morning-only edition. The old names live on in The Gazette & Herald newspaper which the company produces weekly, principally for the rural area of Ryedale to the north and east of York.
Even thouigh it was by then owned by Westminster Press in London, it was locally famous for still having the news print paper being delivered direct in massive rolls by barge up the river from Hull, right up until the mid-1990s, and was the last commercial traffic on the river to York.
