Durham Miners' Association records spanning more than 60 years of coal mining in the North East are now available to browse on the internet.
The minutes of meetings, accident reports and balance sheets have been digitised by researchers at the North East England Mining and Research Archive (Neemarc) at Sunderland University. They will be of use to genealogists tracing ancestors from the North East, as well as students and scholars.
The accident reports show how dangerous the profession was, with accounts of injuries suffered by miners, from those still in their teens to others well into their sixties.
The records also document the support offered by the Association - a branch of the National Union of Miners - to miners, including offering compensation to widows and children of men killed at work.
