Understanding call numbers

Call or shelf numbers are a series of predetermined numbers and letters allocated to items held by the library. They arrange items on the shelves so that items dealing with the same subjects are near each other.

What do the parts of a call number mean?

Call numbers are basically divided into two parts:

  • subject classification: series of numbers that represent the subject area
  • author classification: series of letters and/or numbers that represent the author or title of the information

Some call numbers have a third part for the year of publication or extra author information.

Here is the call number for Spacetime Physics by Edwin F. Taylor, and John Archibald Wheeler, and what the parts describe:

In the Hargrave-Andrew Library
530.11 T239S Subject: 530 = Physics .11 = Relativity Theory
Author: T239 = Taylor S = Spacetime
In Caulfield Library
530.11 TAY Subject: 530 = Physics .11 = Relativity Theory
Author: TAY = Taylor

How do I use a call number to find an item?

It is important that you note down all of the call number, and which part of the Monash collection the item is held in. Then you need to find each part of the number in turn.

For example to find the book: Understanding Enzymes, by T. Palmer (call number 547.758 P176U4):

Call number structure

  1. Locate the first three digits.
  2. Locate any digits following the decimal point. Remember that it is a decimal system, so 547.8 comes after 547.75.
  3. When you have located the number in full, look for the letter, then the next set of numbers.
  4. Check that the last letter and number are correct, to make sure you have the right book and edition.

Some common problems in looking for items

If you can't find an item:

  • make sure you have written down the whole number
  • make sure that you have located the entire number, including all the digits after the decimal point
  • check that you are looking in the correct site or collection
  • look for prefix letters before the number (eg F = folio (large books), Mos = maths, NZ=New Zealand etc)
  • note that some collections (eg Australian Bureau of Statistics (ABS), Microfiche) have their own numbering system
  • check that the item is not already on loan to someone else


Key points to remember when deciphering call numbers:

  • items on the same topic are shelved next to each other
  • every part of the number is important for finding an item
  • work through the number systematically to find the item it describes
  • call numbers vary between libraries - make sure you have the right one
