Why do we careabout the Library of Congress
Classification System?
• It is used to organize the books in our library.
• It is a great example of:
• 2nd order of order organization
• taxonomy
• A really BIG organization project that shows issues that small projects don’t have to deal with
Library of Congress Classification
• 21 classes (categories) that books can be lumped in to
• Further subclasses
• Topics
Compared to Dewey:
• http://www.loc.gov/catdir/cpso/lcc.html
• https://en.wikipedia.org/wiki/Library_of_Congress_Classification
• Less idealogical and more practical
• It show how ONE COLLECTION is divided, not how the world’s information is divided.
Example:
HD 30.2 W4165 2007
• CLASS H: SOCIAL SCIENCES
• Subclass: HD: Industries. Land Use. Labor.
Example:
HD 30.2 W4165 2007
• HD28-9999 Industries. Land use. Labor
• HD28-70 Management. Industrial management
• 30.2 Electronic data processing. Information technology.
Including artificial intelligence and knowledge management

Lab Exercise:• In the pod you are sitting at examine the book given to
your group.
• Have one person start a post titled “LCC Lab”. Include the names of everyone in your group. Record notes on the group’s work.
• Use the LCC system to assign a class and subclass to your book. (Don’t look it up yet, that will come later.)
• Pick a couple of possible alternate classes or subclasses and discuss why these may be better fits.
Lab Exercise:
• Now, look up your book in the library’s SearchIT! tool
• http://bit.ly/SearchIT
• Compare their choice to your choice
• Compare the subject headings to the classification
• What do you think about the differences?
