Title:  MasterFormat®, Master List of Numbers and Titles for the Construction Industry

This publication contains a complete list of the Construction Specifications Institute's recommended taxonomy of section numbers and titles, as well as a key word index to aid in finding the appropriate section number. This is the one resource that should be on every spec writer's "must-have" list. Very useful when adding new sections that are not in your master, vetting sections from other sources, and scoping for best location. Also useful for coordinating between disciplines and between portions of the specification prepared by different consultants. Cross references in the document simplify coordination. 

The editions from 2004 on are similar but a significant departure from the 1995 edition. BSD SpecLink content is kept in sync with the 2004/2012+ Update; MasterFormat updates every two years. Note the Title Sequence Master Notes typically show the MF 95 legacy number where it existed under MasterFormat 1995 as an aid to those needing to transition or backdate to the older standard. The exceptions to this are where the older MF95 system simply ran out of numbers to address building automation system work results that currently fall in Division 25 and a few others.
