BSI marks for copy preparation and proof correction
The British Standards Institution's proof-correction marks are recognised throughout Britain and increasingly around the world. Why reinvent the wheel when you can use something tried and true?
By arrangement with the BSI, the CIEP can now supply copies of its standard for proof-correction marks: BS 5261C:2005 – Marks for copy preparation and proof correction (extracted from BS 5261-2:2005).
Please note we are sorry we are unable to accept orders for the card during the coronavirus lockdown.
This useful 8-page list of the most up-to-date BSI marks, on laminated card, is an essential tool for all proofreaders and copyeditors.
The BSI charges £20.00 for each card. The CIEP charges substantially less:
- CIEP members: £4.00
- Others: £10.00
That's an 80% discount for CIEP members and a 50% discount for others.
The BSI cards may be purchased via the CIEP online shop:
There is a maximum order of 5 cards per customer.
