The records in the MacMillan Bloedel Ltd. fonds span from 1866 to 2002. They represent the records of the three major predecessor companies, - Powell River Company; Bloedel, Stewart & Welch; and H.R. MacMillan Export - as well as records of the amalgamated corporations - MacMillan& Bloedel; MacMillan, Bloedel and Powell River; and MacMillan Bloedel Limited.
