Fiona is based in SE Qld and is an enthusiast of all things art & crafty. She is currently studying her Diploma of Library/Info Services

Feel like you're reading a foreign language? Confused by that scrap of paper with numbers and letters on it?

Believe it or not, you're not alone!! There are many people out there who, for a variety of reasons, can't seem to get their head around how to find a book on the shelf at their local library.

Generally speaking, when you need to find an item (libraries aren't just about books these days!) your friendly library staff are more than happy to help you locate a book, but sometimes one just wants to explore the options on their own, and that's what this lens is designed to do!

Below you will find described in basic terms how to interpret those numbers and letters into the 'shelf address' of that book you've been dying to read!

Or listen to, or watch, or....

What is a Library Classification System?

Why there are numbers and letters

A Library Classification System is essential to keeping a libary's items quick and easy to find. It is the method by which items in a library - such as books, videos, audio books, CDs, CD-Roms, etc - are allocated to keep them locatable. Could you imagine if the book you wanted was randomly put back on a shelf, but no-body knew where exactly it was? Chaos!

Throughout the world, there are many different types of classification system used to keep library collections organised. Each has it's own pros and cons for workability, and are best suited for different collection types.

Different types of Library Classification System

To name but a few:

Bliss bibliographic

Dewey Decimal

Library of Congress

Colon

Cutter Expansive

Universal Decimal

Brinkler

OPAC Terminals

An OPAC terminal is an "Online Public Access Catalogue" computer, available for people to use to search the library catalogue for items available to borrow, often across the all of the affiliated libraries (such as your local council, or university libraries).

Searches can be by title, author, and subject to name a few.

How to read a Dewey Decimal call number

Rule-of-thumb: '123 ABC'!

The call number should be read left to right, and sometimes, when the list of numbers is quite long, top to bottom: ANF 641.5 DELI

The 'ANF' indicates that the book/item you are looking for belongs in the Adult Non-Fiction collection. You may also find variations including 'JNF' or 'YNF', which indicate that the item can be found in the Junior Non-Fiction and Young Adult Non-Fiction collections respectively.

The numbers '641' indicate the broad subject area the item is catalogued under, in this case cooking. The '.5' indicats what subject area WITHIN cooking the item is about, such as curries or diabetic recipes. Often, there will be more than one number after the decimal point/period dot, which helps to narrow down the specific subject area of the book (if you think about it, just 'cooking' can encompass alot of things!).

Finally, the letters 'DELI' are taken from the surname of the author, or sometimes in the event that the book is a collaboration of several authors, the surname of the editor.

When you come to the actually physically looking at shelves part of your search, you should find that each of the aisles have labels on the ends indicating which collaction they are (ANF, AF, etc), and the number of letter sequence on those shelves. It should run in a progressive order, from one and 'A' onwards.

How to read a Library of Congress call number

Rule-of-thumb: '123 ABC'!

The call number should be read left to right, top to bottom:

TX

644

.C33

2008

The 'TX' should be read alphabetically i.e. TA, TB, TC and so-forth. The 'TX' indicates the broad subject area i.e. cooking.

The '644' is a specific subject area WITHIN the cooking subject, such as chocolate, or cake decorating.

The '.C33' helps to narrow down the search further, and is obtained by using the first letter of the author's surname, then using a special code called a 'cutter' to substitute numbers for the new two (2) letters of the author's surname.

There will sometimes be another line with letters and numbers below the inital one, which you read the same way.

Finally, the last number on the bottom, in this instance '2008', generally indicates the year the item was published.

How to read a Fiction call number

Rule of thumb: know your ABC!

The call number will almost always be four letters long, like so:

BUJO

This is usually the first four letters of the author's surname, in this example from BUJOLD, Lois McMaster.

Occasionally, when the book in question is an anthology from numerous authors, it will be cataloged under the first four letters of the title, like so:

KEND

for Kendermore, Dragon Lance Saga Preludes Volume Two.

The other thing a lot of people seemed to get tripped up on was determining which comes first: MAC or MC.

For the purpose of our example, we'll use the surnames McNamara, McDonald, McMaster and MacDonough.

As always, the rule of ABC applies, and you read "Mc" just as you would "Mac".

Therefore:

McDonald before MacDonough before McMaster before McNamara

because as you continue through the spelling of the surname, the 'a' in McDonald comes before the 'o' of MacDonough, and 'm' comes before 'n' for McMaster and McNamara.

A book written by McDonald could sit on the shelf between books written by MacDonald and technically be in the correct place

If you want to get particularly picky about how books by the same author should be shelved, again the rule of ABC comes into play, and you go by title.

Battle of the Cataloging Systems! - Library of Congress VS Dewey Decimal

While there are many forms of library classification system used throughout the world, generally speaking the two (2) classification systems most people will come into contact with are the Dewey Decimal and Library of Congress Classification Systems.

Do you prefer the Library of Congress Classification System, or the Dewey Decimal Classification System?

      I only learned the LCCS in all my years of school. As an adult and college grad. I have had to learn the DDS for the public library in the area I have moved. I always liked the LCCS because I knew it. I'm glad I don't have to learn it now instead of DDC though because the DDS is easier to quickly learn and understand. THe biggest con to the DDS that I have discovered is that lots of libraries change the DDS to fit their local branch, so it is not completely uniform.

    • jenokson 5 years ago

      I work in a school library where we use DDC, but secretly I prefer LC (don't tell my boss!)

    • Fiona Findlay 6 years ago from Queensland, Australia

      Library of Congress (LC) is better! It has the ability to expand for new subject areas without becoming ridiculously long to read.

        Good things about both. Dewey really stinks for the 590s, and LC is great for literary criticism. But all those little numbers...

      • TeacherSerenia 4 years ago

        I'll take the DEWEY any day. The LOC is far to complicated for me.

      • anonymous 5 years ago

        dewey decimal

      • unstucktheory 6 years ago

        Good thing you asked which one I "prefer'! I find Dewey Decimal so much easier simply because it's what I got used to at school and the local library and could navigate to most subject areas i was interested in without having to look things up. Agree that the LOC is much more scalable though :)

          These is a very nice intro to the library. Libraries really are difficult to maneuver...people still don't know what YA stands for and are constantly astonished that we have stuff like DVDs in our collections.
