- Library of Congress numbers (Things)
"See? I told you. It's a Library of Congress number."
"Am I the only one who misses good old Melvil Dewey?"
Melvil Dewey (1851-1931) was most famous for inventing the Dewey Decimal System, in which all knowledge is divided into ten main classes, although he was also one of the founders of the American Library Association (and apparently, he was anti-Semitic and a big fan of the ladies). The ten classes of the Dewey Decimal System go from divine (philosophy and religion) to mundane (history and geography). The ten classes are then subdivided into ten divisions, which are themselves subdivided into ten sections. The decimals help keep it fairly simple to navigate. The Library of Congress Classification, on the other hand, uses letters to sort the books in most research and academic libraries. It's more library-specific than Dewey, which is more knowledge-based, but that quality also makes it harder to add new categories to the Dewey system than to the LoC. The LoC system would be applied to the Hearst library since it's an academic library, but if Logan really misses Dewey that much, all he'd have to do is go to any public library for a reunion.
