Remember Classification Club? Everyone at the Manor is a life member, of course. And we're all rejoicing this week, as the news of another unfeasibly lengthy Dewey number continues to filter through the halls. Twenty-one digits? That's nothing. We'll see your "Rednecks in motion pictures" and raise you with a "Buhler Versatile Inc. Strike, Winnipeg, Man., 2000-2001." As every serious student of the Canadian tractor industry will appreciate, the best place for works on this subject is -- deep breath -- 331.892829225209712743090511. That's a whopping twenty-seven digits, and a clear contender for the title of Longest. Dewey. Number. EVER! It's one that we mapped the other day to a new subject heading approved by Library and Archives Canada in December 2005. The base number for strikes in extractive, manufacturing, construction industries and occupations is 331.8928. To this we added the numbers following 6 in 629.2252, which is the number for tractors, then T1—09 + T2—712743 for Winnipeg, and finally T1—090511 for 2000–2009 (as per the instructions at T1—093–099 Treatment by specific continents, countries, localities ...).
