Trinity Mirror is to publish a series of regional magazines to mark the centenary of World War One telling each the story of each region’s part in the conflict.

The publisher is digging into its national and regional archives to compile a series of national commemorative magazines with five companion inserts for each of its main publishing regions.

The inserts will cover Merseyside, Manchester, the Midlands, the North-East and Wales and will focus on the war effort in that particular region.

The first part of the collection of bi-monthly magazines went on sale this week.

The Mirror had a significant number of staff photographers embedded with the troops in the trenches between 1914 and 1918.

Thousands of the images they secured – previously stored for the best part of a century in their original glass negative format – have now been digitised and made available for the project.

Fergus McKenna, head of licensing and syndication at Mirrorpix, said: “Our new WW1 series is yet another fantastic example of how our national and regional Trinity Mirror businesses work together to deliver first class products.

“I’m especially proud because this is the first major publishing project we have undertaken since our group archives were brought together into a single library in late 2013. The Mirror World War 100 collection perfectly illustrates our unique history as a publisher and highlights what a special asset our archives are.”
