Proofreaders are paid a substantial fee for their work. From 1 April 2006, The NUJ's (National Union of Journalists) suggested rate for proofreaders is £17.50 per hour, though freelance proofreaders will negotiate fess with their clients.
Proofreaders will either check documents against copy, or perform a blind reading, which is looking through the work without checking against a copy.
Proofreaders are able to join the Society of Editors and Proofreaders, which offers training courses for proofreaders, offers to help proofreaders find work, and provides discounts, though a fee is required for membership. There is also a monthly magazine released by the society, which contains useful information for editors and proofreaders. The magazine is free to members, but non-members and retired members have to pay to subscribe.
