People will soon be able to glimpse what life was for World War I soldiers after more than 300 war letters have been transcribed and put on a website.

The website, www.sincewritingyoulast.co.nz, also includes information on the soldiers as well as digitised images of the letters.

The war letters from four Southland World I soldiers have been transcribed by a team of dedicated volunteers and produced by the Invercargill City Libraries and Archives.

The work, which took the eight volunteers more than two years, follows the stories of Charlie McIntyre, Ernie McIntyre, Len Shepard and John Hall, with a combined total of more than 1700 pages of letters transcribed.

Invercargill Public Library archivist Rebecca Smith said the project was its way of commemorating the centenary of World War I.

"The website lets you discover first-hand the experiences of these men as they served our country in The Great War.

"The website will be available online for 10 years. It will not only provide students with a primary source at their fingertips, but will also be of interest to historians, military enthusiasts and adults in general," Ms Smith said.

The website will be launched on March 1.
