The 19 editor pages follow a similar format to the profile pages journalisted.com already offers individual journalists, featuring details such as education, employment and links to published work.
The site also plans to list awards won by each newspaper under the editor as well as formal complaints made about each newspaper under the editor via the Press Complaints Commission.
The profiles will also link to other sites that have biographical information, interviews or speeches given by the editor, according to an announcement on the MST site.
The new pages are part of an effort to make UK editors a little less "invisible", director of the MST, Martin Moore, said in a blog post.
"British national newspaper editors have the power to choose what should be read by over 10 million people in Britain everyday, have the ability to influence public policy, and are regularly invited to meetings at Downing Street and Chequers.
"Yet we know very little about them. So journalisted.com thought it would have a go at making them a little less invisible."
"These are works-in-progress, and as you'll see from some of the profiles, the information in the public domain is very sparse," he added.
"So we'll keep adding to them, and appealing to people to send us more information to fill in the many gaps."
The editors themselves can also go onto the site to edit and add details to their own pages.
