A likely deal for the Boston Globe to print the Boston Herald was announced so long ago (last May) that you’re forgiven if you thought the tabloid was already being produced at 135 Morrissey Blvd.

In any event, the deal — which will cover most but not all of the Herald’s print run — finally became official yesterday. Some 50 union workers will lose their jobs. The Globe covers the story here, and the Herald here.
