MasterFormat® users: As you know, the content of the old website was recently moved to the CSI website. This should improve and speed access for users using single sign-on, but as with any website upgrade, there have been one or two minor bugs.

Among these is the tool which converted MasterFormat® 1995 numbers to current edition numbers. This tool which many users have relied upon is not yet ready to be used on the CSI MasterFormat® site. We anticipate it being available soon, but we didn’t want any users to be confused or spend time trying to locate it.

If you need immediate access to a transition tool, one is included as a download with purchase of the full edition of MasterFormat®
