Unfortunately there is no set definition for what is meant by commercial but the British Library and Copyright Licensing Agency (CLA) have issued a guidance note on the subject.
Visitors to the Library can make self service photocopies and complete the non-commercial copyright declaration form or, for commercial copies, purchase a copyright fee paid sticker for £9 (including VAT). Photocopies are then charged at 10p/A4 sheet and 20p/A3 sheet for members. Non-members are charged 20p/A4 and 40p/A3.
For users requesting a non-commercial photocopy to be sent out by post or fax, there is a separate form to complete which also has a section on it for providing payment details.
We have a separate form for requests for copies from Institution publications, including The Structural Engineer.
Users requesting a commercial photocopy to be sent out by post or fax will need to make their request using this form. A commercial copying fee of £9 (including VAT) will be charged in addition to the normal photocopying or faxing charge per page.
Please note that certain publications, notably British Standards and TRADA publications, are not authorised for commercial copying. A list of these excluded categories and excluded works can be viewed online.
Whichever form you need to use, please make sure that you read the conditions of the declaration that you sign as this is important legislation and it is your responsibility to adhere to it.
