It was originally part of a single publication, the 1973-founded St Albans, Harpenden, Welwyn Garden City, Hatfield Review, but became a separate edition in 1983. It’s published by Review Newspapers, part of Newsquest (London). The editorial offices are in Watford.
It has no website of its own; the URL below redirects to the St Albans & Harpenden Review‘s website (which however has no separate pages for WGC and Hatfield).
It comes out on Wednesdays. An e-edition (of the St Albans & Harpenden Review) is also available free on the website.
