Note: JCGM 100:2008 is also available in HTML form from the JCGM portal on ISO's website.

The JCGM Working Group 1 (JCGM-WG1) is producing a series of documents to accompany the GUM. The first four of these documents have been approved and are available for download as PDF files. Printed copies are available for purchase from ISO.
