Library workings Survey

Hello friends!

I'm doing a class in cataloging and classification. I'm learning about the various classification systems, like the Dewey Decimal system.  I'm familiar with the way libraries in the USA classify books and I'm learning about the libraries in Scotland (because that is where my university is), but I'm curious to other countries.

In the United States, public libraries use the Dewey Decimal and the universities and national library (Library of Congress) use the classification system called the Library of Congress system.

What do the libraries in Canada use?  What about the rest of Europe? Other countries?

I don't guess it's really important that I know about other countries ways of library classification.  I guess I just need to know what they do in Great Britain (for my grades in class) and what they do in America since that is where I live and will work.  However, my class is really an international class.  I'm the only American with many from Great Britain, one or two Canadians, other Europeans, some Africans, and even folks from Asia.  It reminds me that there are many libraries in many countries with many languages and somehow all those libraries must classify their books.  I'm simply curious, but learning how the rest of the world libraries work can help me understand my own country.

I love this movie:  UHF.  Watch now and see Conan, the Librarian!
