An official announcement is expected from the five publishers today.
The group is reported to be seeking a permanent chief executive and will focus on developing common standards for digital editions in a concerted effort to make money from online content.
The publishers are thought to be strongly considering developing their own e-reading platform to combat Amazon's Kindle, which takes 70 per cent of revenues and retains most of the reader data. This has angered publishers who want control of the data so they can form closer relationships with their readers.
The news comes after Hearst last week said that its Skiff online service (formerly known as FirstPaper) will launch next year, selling digital versions of newspapers and magazines for a variety of devices. Additionally, Time Inc last week showed an online demonstration of a digital edition of Sports Illustrated.
Condé Nast and News Corp have both also been looking at various digital editions. These include Condè Nast developing a version of Wired suitable for e-reading and tablet computer devices.
News Corp has previously said it is interested in developing an e-reader of its own.
