Find a Book on the Shelf
Step 1: Write down the call number of the item that you want; a call number is like an address for the book or film. Here is a screenshot from the catalog with the call number outlined:
Step 2: Look at the first one or two letters of the call number to determine which floor in Gelman to go to. For this example, our call number is E185.615 .C6335 2015 so we use the letter 'E' to determine which floor this book is on based on the ranges below. 'E' is alphabetically between 'A' and 'HD' so this book is on the 4th floor.
Step 3: Once you get to the correct floor you will first find the aisle where your item is located.
First, materials are shelved alphabetically by the first letter or letters (In the example above, the first letter is 'E').
Next, they are arranged numerically by the number following the letter(s). (In this example that is the number 185.615). Keep breaking down the call number one segment at a time to find the aisle, the shelf and the position on the shelf.
185.615 [Read as a whole number and decimal]
.C [Read alphabetically]
6335 [Read as a decimal]
