Collocation and Controlled Vocabulary

Salutations!

My INFO 5300 Organization of Information class during the Fall 2022 semester was eye-opening to things I knew instinctively yet couldn’t articulate, as well as broadening for my horizons to what theoretical underpinnings support some cataloging decisions.

I connected effortlessly with the assertion that humans naturally organize information and laughed knowingly at the quip that people are either filers or pilers (Joudrey & Taylor, 2018, p. 2)! Collocation, that is “[organizing] to bring similar things or ideas together into groups…[such as] books on the same subject or sound recordings in the same musical genre” (Joudrey & Taylor, p. 3), resonated with me. Once I stopped reading the word as “collation,” putting pages in numerical order, and actually looked at it while remembering the definition provided, I realized collocation could be used to describe how my personal shelves are categorized; until now, I never had one term to explain why all my books on or by Laura Ingalls Wilder are together, followed by my dance/ballet books, with my DVDs grouped by genre and the actresses important to me. On my own, I connected the concept of collocation to a cataloger’s reliance on the Dewey Decimal System when working with a certain topic, such as the call numbers of all the juvenile books about pandas being J 599.789.

During further examination of Chapter 1 of Joudrey and Taylor’s The Organization of Information, I found the statement “controlled vocabulary ensures consistency in subject representation and allows for collocation” (p. 17), which validates my inclination. I was helping to train a new staff member yesterday, and we were looking at a MARC record with our director of youth services. We discussed how a child might want to search for “bunnies” in the OPAC, yet the Sierra catalog typically prefers the subject term “rabbits,” since that word is typical “librarian speak” as we call it. When searching for materials on raising pet rabbits, back in one of my elementary schools, I remember my young patrons would not get results for “bunnies” because Follett Destiny used only “rabbits.” Actually it seems more common nowadays than I anticipated for words like “bunnies,” “puppies,” and “kitties” to be the titles of some non-fiction books for children. It seems the publishing industry is becoming increasingly cognizant of childhood vocabulary trends. My public library’s OPAC yielded 206 different items across all branches and several formats featuring the word “bunnies” somewhere in the resource records through keyword searching; a search of “puppies” populated 559 results, while “kitties” offered a scant 40 results; the board book Bunnies by Gail Gibbons has its subject heading as merely “Rabbits–Juvenile literature.”

Dewey Book Tasting (Grades 3-5 Lesson)

Hello Everyone,

When my grades 3-5 classes were discussing New Year’s Resolutions, I shared mine: to read 10 non-fiction books from our library media center.

So, I thought students needed an introduction/refresher (depended on their background knowledge) to/of how non-fiction books are organized.

Hence, the “Dewey Book Tasting” Exploration!

After a student read our session’s “I Can” statement, I explained that non-fiction books have three-digit numbers that group them into large categories. It is important to know what numbers go with which topics, so you can find things in different libraries (like in middle school/high school or when you visit the public library).

Using my previously-assigned table groups, I had each table of students rotate to different tables to explore different broad groupings of non-fiction topics Each table was asked to list the topics they had in their book stacks and come up with a large topic name that each book topic could fit into. I chose books from the 500s, 600s, 700s, 900s, since students are mostly interested in science, technology, domesticated animals, activities, the arts, history and geography, and biographies.

Throughout the activity, students charted their findings and their rotations on one page; they were experiencing the Dewey Decimal System in action without the categorization being called that. For example, some groups came up with the large topic for a handful of 700s books being about “things to do,” while others mentioned “nature” as the topic for the 500 level books they had, mostly plant and wild animal books.

Big 10 Dewey Non-fiction Categories (Grades 2-5)

Hello Everyone,

This week my library students in grades 2 through 5 have been discussing the Big 10 categories non-fiction books have been placed into on our library shelves. ​We can use the “Dewey Buddy” to help us remember the Big 10 categories.
