Helping School Librarians Understand Dewey 300 Social Science

Posted on March 25, 2021 by Barbara Paciotti

If your school library collection is like mine, the 300 Social Sciences takes up large part of your Dewey area. What boggles the minds of students, teachers, and School Librarians alike is the mish-mash of disparate topics with an arrangement that doesn’t make much sense. Plus, the 300s seem to have many books that belong in other Dewey sections!

As a lover of the Dewey Decimal Classification system and a college major in the Social Sciences, I hope to help you understand this Dewey Class…and suggest some changes that might better serve your students and teachers.

THE METHOD OF ASSIGNING DEWEY NUMBERS

Remember that Dewey Decimal Numbers are assigned by discipline, that is, the field of study—the profession. How does that differ from subject?

Subject asks, “What is this about?” and is the topic of a book—the informational content inside.
Discipline asks, “Who is this for?”—who will use this—and assigns a Dewey number so those folks find their professional information in one place.

A particular subject, then, can be assigned more than one Dewey number depending on which profession uses the material for their own purposes. Here’s a DDC example of a simple water report that can apply to 5 different Dewey numbers:

Use 333.91 for monitoring to protect water quality, 553.7 for chemical & biological status, 363.6 for assuring compliance with standards, 628.1 for technical aspects of water treatment, and 628.93 for effectiveness of sewage treatment. (Abridged 15, p65.) [edited for brevity]

Also keep in mind that books for more than one discipline or subject are assigned the lowest Dewey Decimal number that includes all disciplines—using the rule of two or the rule of three. This explains why the 300 section is so large: its numbers are lower than 6 other Dewey Classes, so multiple subject/discipline books are placed in the 300s rather than where we might need them for our school curriculum.

Visit my blog posts on Dewey 590s Animals for more about disciplinary alignment, and Let’s Put Dewey Decimal Books Where Students Can Find Them for more on the rules of two & three.

WHAT DOES 300 SOCIAL SCIENCE REALLY INCLUDE?

Calling the 300s “social sciences” may be a slight misnomer: the social sciences include geography and history which Dewey places in the 900s, as well as psychology which Dewey places in the 100s. Thus, of the 7 social sciences, only sociology, anthropology, political science, and economics are in the 300s.

Since these four disciplines are about social relationships and the organization & function of human societies, I’ve chosen a more specific name for this Dewey number which students understand better than the generic “Social Sciences”:

Dewey 300 – Society, Government, and Culture

Unfortunately, the materials for these 3 broad headings are not necessarily in contiguous divisions and sections, so here’s the 300 divisions each one encompasses:

Society: 300 Sociology & anthropology and 360 Social problems & services
linebreak
Government: 320 Political science, 330 Economics, 340 Law, and 350 Public administration & military science, and 380 Commerce, communications & transportation
linebreak
Culture: 370 Education & 390 Customs

NOTE: You probably won’t have any 310s in your school library because it’s just for statistical records.

SOCIETY

300 Sociology & anthropology
The 300s begin with society, specifically sociology & anthropology. If we consider psychology (the 100s) as the social science of the individual, then 300-307 is the social science of groups. It includes behaviors like bullying, gangs, prejudice & discrimination; interactions such as social change & civil disobedience; and relationships between individuals, groups, and communities. It does have one section important for School Librarians:

305 Groups of people introduces those used throughout the rest of the 300s by age, gender, social class, race, ethnicity/ancestry, occupation, and illness/disability. School Librarians need to build this section with high-quality, equity-sensitive resources because it can so strongly influence the minds of our students.

360 Social problems & services
This division may be, I suspect, the one that gives School Librarians the most headaches. It’s categorized according to type of problem and how the service is provided:

for specific groups of people (according to the groups in 305),
as governmental services such as public safety, crime & punishment,
by public & private societies & clubs,
by commercial insurance services,
by associations.

Some books in this division are victims of the rules of two or three, such as substance abuse and mental & physical disorders. I relocated many of these to appropriate higher numbers for better student access.

363 Other social problems and services
If the 360s are problematic, this section is particularly exasperating for School Librarians. Like any “other” section of the 300s, it’s a dumping ground for disparate topics. To understand what’s covered in this section, think of it as the basic needs of Maslow’s Hierarchy: physical needs for human survival, and our need for safety & security.

363 begins with Public safety from hazards, followed by police services with crime investigation & forensics, and ‘safety’ from moral ‘problems’, like alcohol, gambling, prostitution, pornography, homosexuality, drug trafficking, and abortion. The public safety portion ends with another dumping ground—363.3 Other aspects of public safety which has just about everything else, from censorship to terrorism to gun control to firefighting.
linebreak
363.34 Disasters is actually disaster relief, and school libraries may have sizeable sections here on earthquakes & volcanos, floods & tsunamis, and other earth & weather-related disasters. I relocated many of these to 551 Earth science so they’d be together for science class assignments.
linebreak
363 ends with physical needs and the services that provide for it. This section includes housing, public utilities like water treatment, food supply issues including malnutrition of the poor & famine, and population issues like family planning & birth control, sterilization, and over-population.
linebreak
363.7 Environmental problems is another perplexing spot, because so many popular school topics about environmental protection are crammed in here. I added additional numbers (below) to better define the different topics:

Description	Dewey number
Environmental problems	363.7
Sanitation – waste control, recycling	.72
Pollution	.73
By source – oil, toxic chemicals, acid rain	.738
Of specific environments – air, water, soil Global warming from CO2 (greenhouse effect) & ozone layer depletion (You may find ozone books in .738 due to the rule of 2 regarding refrigerants, but I moved mine here because it’s a global issue of the atmosphere.	.739
Noise pollution	.74

GOVERNMENT

It’s no surprise that 320 Political science, 340 Law, and 350 Public administration & military science align with the 3 branches of U.S. government. (Be aware that other countries may not have this structure, but most of those books are in the 900 section. )

320 Political science includes civil & human rights, the political process & elections, relations between nations, and the legislative process, hence, books about the U.S. Congress.
340 Law covers international, constitutional, regional/state, economic, criminal, and civil law, and includes the United Nations, the U.S. Constitution & Bill of Rights, and the U.S. Supreme Court.
350 Public administration covers the executive branch—the U.S. Presidency, the Cabinet, and management of departments or agencies such as national security, justice, foreign affairs, health & education, and those with economic or environmental oversight. 355-359 military science covers all branches of the military, which is administered by the head of state.

MAKING THE 300’S MORE STUDENT-FRIENDLY

330 Economics
Economics is probably nestled between 320 and 340, because legislatures (320) set taxes and budgets. This division also includes careers, money, banking, credit cards, the stock market, and taxes. (You may also see books on socialism & communism because they are economic-based systems, but I prefer all books on types of government together, so I relocated mine to 321.)

School Librarians need to know that 330 also covers economic development and management including that of natural resources, so that’s why we find a sizable group of books in 333.7-333.9. I actually added decimals to my books to differentiate between the different topics, according to the table below:

Description	Dewey number
Economics of land & energy	333
Land, recreational & wilderness areas, energy	333.7
Conservation & protection	.72
Land	.73
Grasslands	.74
Forest lands	.75
Rural lands	.76
Urban lands	.77
Recreational & wilderness areas	.78
Energy – alternative, renewable	.79
Primary forms of energy – solar, nuclear	.792
Secondary forms of energy – renewable	.793
Photovoltaic energy	.796
Subsurface resources – nonrenewable	333.8
Fossil fuels	.82
Geothermal	.88
Other natural resources	333.9
Water energy – hydroelectric	.91
Wind energy	.92
Biofuels, biodiversity, wildlife refuges	.95

380 COMMERCE, COMMUNICATIONS, TRANSPORTATION
This division may seem redundant with topics in 330 Economics; however, this division is for regulatory aspects (law & public administration) and public consumption—the socio-cultural perspective of ‘products’ & ‘people’, that is, services that sustain or benefit our way of life. Here we find:

domestic & international trade
the infrastructure for communications—postal, telegraph, computer, wireless (radio, television, satellite), and telephone
the infrastructure for transportation, including railroads, waterways, air traffic, roads, local mass transit, and pipeline transport of utilities.

You may see here books that are topical with those in the 600s, and they may get increased circulation by relocating them there.

CULTURE

Near the end of the 300s we find the two divisions relating to culture and it’s institutions.

370 Education
Education is how our culture and traditions are passed down from adults to children. Most books with this division number will be about teaching, so will be shelved in our Professional collection. You may, however, want to do as I did, and build a circulating group of books on schools for the historical time periods our students study in their social studies classes, and books on study skills topics.

390 Customs, etiquette, folklore
This is the division we probably think of when we refer to “culture”. It differs from 300 Sociology & anthropology in that 300 is about groups & institutions, whereas this division is about our personal or informal way of life. We find here sections on personal adornment such as clothing & accessories, cosmetics, jewelry, and body alteration like tattoos and body piercing.

We also find sections on customs for home & family life, death, and special occasions, like marriage, festivals, birthdays, and holidays. Interestingly, it’s also where we find such arcane topics as cannibalism and taboos. The topics may seem similar to 306 Culture and institutions, but 306 is about behaviors and interactions, whereas these sections are for specific celebratory rituals.

398 Folklore, especially 398.2 Folk literature can be a sizable section in school libraries, and if yours is not well organized, you might want to read my post Let’s Put Dewey Decimal Books Where Students Can Find Them. I offer alternate numbers to group these books according to how our students study folklore.
linebreak
At 398.8 Rhymes and rhyming games we find Mother Goose and other nursery rhymes, as well as lullabies and jump rope rhymes. If your school library serves PreK, you may want to build this section and relocate related books from other areas to make it easier for you and your teachers to find them all together.

WHEN THE 300’s ISN’T THE RIGHT PLACE

Many School Librarians get frustrated with the Dewey Decimal Classification system and want to “genrify” it like we do our fiction literature. I believe this is because they don’t understand the purpose of DDC:

“works that are used together to be found together.”

It’s that purpose of DDC which gives us the freedom to change a Dewey number. Since our disciplinary use is different than career professionals, we can locate books where they will better serve the needs of our school curriculum.

For example, one DDC rule of two/three victim is U.S. slavery before the Civil War. Books on this subject can be found at 2 places in the 300s:

306.3 Culture/economic institutions if the content is slavery as an established socio-economic culture of the time.
326 Slavery and emancipation if the content is about abolitionism and antislavery movements, the political issues of that time period.

I didn’t like either location, so I changed all these books to a little-used but legitimate DDC number where students would find the books within the historical time period:

973.71 Civil War – Social, political, economic history

This number already includes the Underground Railroad and the Emancipation Proclamation, so now all U.S. slavery books are together. After relocating the books, students easily discovered them there and even thought I’d bought new ones!

So, School Librarians don’t have to give up Dewey for radical organizational changes to make their school library more student-friendly. For additional creative ways to use DDC, get my new E-book How to Make Dewey Decimals Student-Friendly found at No Sweat Library, my Teachers Pay Teachers store.

Let’s Expand Our View of “School Library Orientation”

Posted on August 19, 2019 by Barbara Paciotti

School Librarians know the importance of our students’ first library visit, so at the beginning of each school year, “school library orientation” becomes a hot topic on library listservs, social media, and blogs. Folks request ideas, asking, “What can I do differently this year?”

A couple years after I simplified and customized my school library orientations with English Language Arts classes, I came to an astounding realization:

EVERY subject-area’s “first” library visit of the school year is a “library orientation” for THEM!

I’m suggesting that you don’t need to keep trying new things every year with the same subject class. Rather, expand your view of what “library orientation” means and customize an “orientation” lesson for every grade level and subject area in your building!

Allow me share how I developed a series of “library orientations” that brought 6th grade ELA, Social Studies, Math, Science, and Elective classes into the library at various intervals during the first several weeks of school. Once you try this, I know you’ll love it, and your subject area teachers feel pretty special having their very own unique library orientation customized to their content. (Even an elementary librarian can focus each class’s visit on new library materials or features, so it’s a like another orientation.)

ENGLISH LANGUAGE ARTS “ORIENTATION”

I’ve written about how I simplified my 6th grade library orientation, so students aren’t overwhelmed with too much new information. Keep in mind that for lowest-grade-level, new-to-the-school students, our school library is completely new to them, and our lesson is “fresh” for them, even if we’ve done it a dozen times! Because each new year is a totally new group of students, I’m as enthusiastic about this lesson as I was the first time.

Our ELA classes begin the year studying narrative text, so we focus on how to choose one good book from the new-to-them Fiction area. My lesson is followed by plenty of time to browse the Fiction area of this “new” library, after which we have extended silent reading while I do a quiet invited checkout. This standard procedure establishes a reading culture for ELA’s every-other-week library visits for the rest of the school year.

SOCIAL STUDIES “ORIENTATION”

After the ELA visit, we can bring in other 6g subject-area classes and do a “library orientation” customized to their particular content. I’ve written about my Special Collections for Social Studies, so I have 6^th grade Social Studies classes visit a couple weeks after ELA to learn more about their “new” school library: the GlobeTrekkers Special Collection of fiction & Dewey books that support their study of World Cultures.

The first part of the lesson is returning books and a library expectations lesson, giving students a few policies & procedures for their “new” school library. Then I introduce Content Area Reading and why it is important.

Educators have learned that reading comprehension isn’t so much about word recognition as it is about conceptual understanding in context. That is, students become better readers as they accrue background knowledge of various topics, so the more they read, the more they know.

Yes, Dr. Seuss instinctively told us this years ago in his book
“I Can Read With My Eyes Shut!” and it just took brain researchers a while to confirm that.

Now I don’t tell all this to kids…I just tell them that the more GlobeTrekkers books they read, the better they’ll do in Social Studies and get better grades!

I show them how to identify GlobeTrekker books in the search results from our online book catalog, and when they hear they can check out a GlobeTrekker Dewey book and, if needed, a new fiction selection for their ELA class they are excited to begin browsing. We follow the same procedure—silent reading & invited checkout—which reinforces with Social Studies the reading culture that was established with ELA.

MATH “ORIENTATION”

I’ve also written how it makes sense to do our Dewey lesson with math classes which has students locate decimal numbers on the bookshelves. When 6^th grade Math classes enter the library, students are so puzzled about what they are doing here…with their math class? That, in itself, sustains engagement for students—who apparently have never done anything like this before.

Keeping the lesson focused on numbers makes it easy for students to relate the Dewey number they see in a book search to a location on a shelf, regardless of the topical content of the book. After the lesson there is plenty of time for students to browse for up to new books, either Fiction or Dewey depending on what they already have checked out. The 6g boys are especially eager to find their favorite informational books in this “new” school library: aliens, cars, sports, and drawing, as well as the Guinness and Believe-It-Or-Not books. And we continue our standard reading & checkout procedure, which reinforces with Math the reading culture we established with ELA and Social Studies.

Three customized lessons with 3 different subject area classes have progressively given our “newbies” what they need to effectively use their “new” school library.

We have imparted our policies & procedures when applicable, so students are not overwhelmed with too much new information to remember.
We have established our school’s reading culture of silent sustained reading (we call ours DEAR—Drop Everything And Read).
We have gradually built up the number and type of books students can check out, so during the early weeks of their new school experience they needn’t keep track of too many books.

SCIENCE “ORIENTATION”

By now our 6^th grade Science classes are well into their unit on Energy and are ready to begin their project on alternative energy resources. The timing is perfect for an introduction to our online subscription services for middle school, which are completely different from those in elementary school.

Most “newbies” come to us from feeder elementaries, but many are new-to-district students. Thus, I begin this “online library orientation” with Digital Citizenship and direct students to our online library resources webpage to prepare for the WebQuest lesson.

I’ve written about my guided WebQuest that introduces just 3 subscription services to 6^th graders—an encyclopedia, a periodical database, a topical reference e-book—with each segment looking only at the specific features of a service they’ll need for the project.

This is a full-period lesson, and each segment has students reading for content information and citing sources as they fill in the WebQuest worksheet (or HyperDoc). Students come away well-prepared to research their project, and I also provide a cart of books for the classroom to supplement the online tools.

To illustrate how favorably teachers respond to customized lessons, shortly after this, 6g Social Studies has an “online orientation” WebQuest using our countries of the world databases. Students gather country data into a spreadsheet app for comparison, and then learn to automatically generate a graph.

ART & SPANISH “ORIENTATION”

By this time we are through the first 9-week grading period, yet I’m not quite finished. Remember, any subject-area class that visits the library for the first time gets a “library orientation.” So, I begin the second grading period with a customized orientation for 6g Art and 6g Spanish. Because these 2 subjects alternate semesters, all 6g students receive this lesson during the first semester.

Both these lesson visits introduce Cloud Computing & Netiquette featuring our online email service. It is a guided lesson, similar to the WebQuest, that examines 3 features of the service: email, blogging, and discussion forums. I always let the other 6g teachers know when I do this popular lesson, so they can begin using the service for their own courses.

INFORMATIONAL CONTENT “ORIENTATION”

I’ve written, too, that making ELA and Math orientations about location allows me to bring other subject areas into the library for content-specific lessons. During the second grading period, 6g Science returns to the library during their Classification & Organization unit.

The lesson allows students to explore the Dewey 590 Animals section, whose disciplinary organization mirrors that of scientific classification, thus reinforcing content for both science & library. The lesson also reviews the parts of informational books so students learn ways to dig into a book’s content to find and extract what they need.

HIGHER GRADE LEVEL “ORIENTATIONS”

Lest you think I ignore our 7^th and 8^th graders, here’s a list of the “library orientations” I’m providing for them during this same time period:

7g & 8g ELA – Narrative Fiction & first book checkout
8g Social Studies – The American colonies, a U.S. History project
7g Math – adding/subtracting decimals & locating Dewey numbers
7g Social Studies – First Texans, a TX History cooperative learning activity
7/8 Theater – Multicultural folktales, creating one-act plays
7g Social Studies – WebQuest on European explorers, a TX History project
8g Spanish – Weather reports & introduction to video broadcasting
8g Health, 8g Careers – books, ebooks, online services & websites

I know you may not think of these as “orientations,” but if view each library visit as an entirely new experience for that group of students in that subject class, all our lessons become “library orientations.”

THE POWER OF “SCHOOL LIBRARY ORIENTATIONS”

I’ve discovered it doesn’t matter how good a librarian students have had before they arrive in our school. These “library orientation” lessons are always powerful because they are bite-sized pieces, scaffolded over time, helping students gradually learn—and remember—how to use every aspect of our library services.

To make successful, carefully crafted lessons, we must have a comprehensive view of each grade level’s total library experience, for both subject-area curricula and the library curriculum. I created my Curriculum Matrix for just this reason, and I keep it updated so it is always ready to be referred to.

Our attitude toward “library orientation” is a reflection of our mindset about our entire School Library Program. We want every student experience with us to be a memorable one, offering meaningful lessons that never get old.
