December 10th marks the birthday of Melvil Dewey, best known for the organizational system named after him. Dewey was also a founder of the American Library Association.
Librarian confession time: I am less familiar with Dewey than with Library of Congress. I cut my teeth in academic and museum libraries, and they all use LoC, not Dewey. I know most librarian have Dewey committed to memory, they know their 500s from their 900s whereas I… have not a clue what those are. And that’s ok! You don’t have to have Dewey committed to memory to appreciate the impact he and his system have had.
There’s plenty of material out on the internet and in library publication around the history and development of the DDC (Dewey Decimal Classification). I’m not wading into philosophies on this one– its a living classification system, and one I don’t use every day. What I will note is that this system predates LoC by several decades, and it was a step forward from fixed locations for books based on accession date. That way lies biology next to Dickens next to Freud next to an Encyclopedia. Easy to find when things were added, less easy to research, oh, any given thing. If you’ve walked into a library– pretty much any library– you have benefited from relative location, whether the spine labels are DDC or LoC.
For the record, I did go find the table of Dewey numbers, and I’ll share it in case you need it (though any public library I’ve been in tends to have signage that says what the numbers mean, bless the librarian who came up with that.)
