Finding your book with Dewey Decimal Shelf Marks

Finding your book with Dewey Decimal Shelf Marks

HELP! How do I find my book?

Finding your book with Dewey Decimal Shelf Marks may seem confusing at first but really it is very straightforward. First off, make sure you have checked your book is available by looking it up on our Library Catalogue: LibrarySearch

For help using LibrarySearch read our quick guide here: Quick Guide to LibrarySearch

Not only will you find the shelfmark that will help you locate your book, but it will also show you if copies are available.

What’s it all mean?

Green means go! So if you see the words “available at” like in the above picture. You know you should be able to find the book on the shelf.

Here you can see that there is an available copy of this book. The word “available” is green (for yes we have it) and it is located at Merchiston Library shelfmark: 891.7342 BUL

Hurray! But now what?

Now you can go find your book!

The shelfmark is your book’s location so you will need to find it (kinda like a very simple treasure hunt!)

Start by matching the first part of the number: 891

891.7342

Once you have located the 891’s it’s time to delve deeper. Now you need to match the digits after the 891.

891.7342

That’s the 7342 after the decimal point. These numbers help narrow down the subject.

Once you have all the numbers matched you look at the Letters, in this case, BUL.

891.7342 BUL

The letters usually refer to the author or editor, not the title.

The author of this book is Bulgakov, so BUL are the letters to match.

These go in alphabetical order so work your way along till you find your book.

Quick synopsis:

  1. Match the first 3 digits
  2. Match the digits after the decimal point
  3. Match the letters

—————————————————————————–

It’s as simple as that…ok maybe not that simple!

History

This Organisational system was conceived by Melvil Dewey in 1873 and first published in 1876. It is one of the most widely used in the world.

Use

The DDC as it is shortened to, is used to organise books by subject. Each item is given a shelf mark identifier so it can be located easily. The main subject areas are:

000        Computer science, information, and general work

100        Philosophy and psychology

200        Religion

300        Social sciences

400        Language

500        Science

600        Technology

700        Art and recreation

800        Literature

900        History and geography

The first 3 digits are the main subject area.  The numbers after the point give a subsection. After the numbers there are 3 letters to represent the author or editor. For example 941.34  DAI This refers to a book on Edinburgh by David Daiches.  Books with the same DDC number are shelved first by their number, then in alphabetic order by author or Editor.
