This article tells you about scanning anything larger than A3 in the library.
You can scan things larger than A3, but this is not self-service. Large format scanning is available in the Map Library on the first floor of the library. Bring your materials to be scanned and a USB stick, and one of the librarians will be able to help you. Each floor in the library also has two A4 scanners, and the top floor has an A3 scanner.
Unlike A4 and A3 scanning, there is a charge for large format scanning, which is deductible from your printing account. It will usually come to £2 per scan, regardless of size, resolution or scan mode.
Please note that all scanning must comply with copyright law.
