DDC 040-049: The Abyss

A Teach Me How To Dewey production

The Rundown:

Darkness. Emptiness. Eternally nothing.

This is the first and only unassigned ten-spot in all of Dewey. It used to be the home of Biographies, but most libraries separate biographies into their own section, leaving this vacant lot to the weeds. Of course, on the shelves the 030s and 050s will flow together seamlessly, but in our minds and hearts we all know and carry on the memory of the ancient denizens of the 040s.

The Rundown:

  • 030 General encyclopedia works
  • 031 Encyclopedias in American English
  • 032 Encyclopedias in English
  • 033 Encyclopedias in German
  • 034 Encyclopedias in French, Occitan & Catalan
  • 035 Encyclopedias in Italian, Romanian & related languages
  • 036 Encyclopedias in Spanish & Portuguese
  • 037 Encyclopedias in Slavic languages
  • 038 Encyclopedias in Scandinavian languages
  • 039 Encyclopedias in other languages

You want facts? They got your facts right here. Perhaps this section should be renamed “Bathroom Reading” as there are encyclopedias and fact books galore, including the perennial favorite Guinness Book of World Records and multivolume and multicolored World Book. Once the behemoths of research, this type of printed books seems to be either dead or dying as a primary resource for in-depth study. I feel like a dinosaur for remembering having the set at home and actually using it for school assignments. Despite their diminished status, I’ve come to see them as a great place for serendipity to reign. Open up to a random page and you’ll find something interesting or informative or even delightful.

Just imagine how differently Breaking Bad would have ended if Walter White had stocked his bathroom with encyclopedias instead of a personalized book of poetry. I’m not saying encyclopedias are better than poetry, but I guess I kind of am. Perhaps I’ll change my tune (or my verse?) when I get to the 800s.

DDC 020-029: Meta-Dewey

A Teach Me How To Dewey production

The Rundown:

  • 020 Library & information sciences
  • 021 Library relationships
  • 022 Administration of physical plant
  • 023 Personnel management
  • 024 No longer used—formerly Regulations for readers
  • 025 Library operations
  • 026 Libraries for specific subjects
  • 027 General libraries
  • 028 Reading & use of other information media
  • 029 No longer used—formerly Literary methods

We’re getting meta up in here. I suppose it’s fitting that the section on libraries should be towards the beginning. Imagine how much this section has changed from Melvil Dewey’s time until now. I wonder how blown his mind would be by the Internet and online catalogs. It’s something we modern users take for granted. I’m old enough to remember using card catalogs, but kids these days (\*shakes fist at sky*) don’t have a clue. Whether that’s good or not is debatable, I suppose, but so long as they’re using the library I’d call that a victory.

Speaking of victory, this section is the first thus far that has books I’ve already read, two of which are below. Yeah reading!

Bibliographies of all stripes serenade perusers of the stacks like the Sirens in The Odyssey, each its own rabbit hole of bookish delight. Be careful not to linger for too long here, though, as there’s so much more to see. (Although, if you’re already overwhelmed by the panoply of book choices before you, then perhaps a curated bibliography is a good place to start your reading adventures.)

This Is How We Dewey: A Primer

A Teach Me How To Dewey production


Ready for the Snapchat summary of Dewey? Here it goes:

The Dewey Decimal Classification (DDC) organizes library material in a numerical hierarchy by field of study. Each one has its own 100-level placement, called a class:

  • 000 – General works, Computer science and Information
  • 100 – Philosophy and psychology
  • 200 – Religion
  • 300 – Social sciences
  • 400 – Language
  • 500 – Science
  • 600 – Technology
  • 700 – Arts & recreation
  • 800 – Literature
  • 900 – History & geography

Each class has its own 10 subdivisions, which have their own subsections, which become more specific the deeper they go. So a book with a Dewey number of 300 will be more general than one with 301.355. Books are organized on the shelf in numerical order, with books with the same Dewey number organized alphabetically by author. (It’s a lot easier to understand when you see it on the shelves, so go visit your local library!)

A book’s Dewey number has two components: its class number (i.e. a number that designates its place on the shelves) and three letters, which usually are the first three of the author’s last name.

So in my library, David McCullough’s Truman has a Dewey number of 973.918 MCC, which got that because it’s in:

900 History & geography
– 970 General history of North America
– – 973 General history of North America; United States

The numbers after the decimal point identify the material more and more specifically by geography, subject, language, etc. And because David McCullough was the author, MCC is tagged onto the end.

That’s basically it. How an item gets cataloged fully – with subject headings, physical description, and all that extra info most non-library folks don’t care about – is both an art and a science, and one best left to professional catalogers because they actually enjoy doing it. But going forward, we’ll be just fine with the basic knowledge of what a Dewey number is and why it’s important for libraries.

Two-minute tutorial done. Let’s Dewey this!

Dewey is dead; long live Dewey

The Dewey Decimal Classification (DDC) is kinda weird. For today’s app-ified patrons, it’s not very intuitive and seems tattered, like one of the old books it classifies. But despite what the sayers of nay say, it’s not time to dump Dewey. Instead, we should try to get to know it a little better.

Librarians encounter Dewey every day while finding books for patrons, weeding the stacks of old books, and selecting new material for the shelves. Yet it can be a bit hard to understand at times, even for librarians. How can such a fusty system be made fresh again?

Teach Me How To Dewey exists for four reasons:

  1. To better familiarize library users with the library’s foundational organizational system (i.e. the thing that makes it all work);
  2. To shine a light into the stacks, so to speak, and show the people who don’t use libraries very often what’s available freely to them;
  3. To show why books and libraries are friggin’ awesome;
  4. To disseminate as many Dewey-related puns as possible.

I’ll tour through the DDC ten decimal points at a time, highlighting a few representative/intriguing/weird books from each section.

Libraries are full of amazing things. Here’s hoping Dewey will help us find them.
