Getting the BNC
You can download the BNC for free from the Oxford Text Archive.
The BNC used to be made available on optical disks until March 2014, and was distributed with a copy of the Xaira software. We don't support Xaira any more, and there are increasing problems with getting it to work on the latest hardware and software. Optical disks are going out of fashion, and faster networks mean that downloading the BNC is now a feasible option for most users. Offering it for download also means that we don't have to charge any fees.

If you really want to install the Xaira software, please visit the BNC XML and Xaira installation pages for instructions, but please note that the University of Oxford does not support the Xaira software.
