What is a call number on a book?
In library and information science, a call number is a unique identifier for a book or other materials. Call numbers are usually assigned by libraries to help users find the items they are looking for. Most call numbers are numeric or alphanumeric, but some may be purely alphabetical.
How do call numbers work?
Call numbers are like an address for your books. They tell us where the book is on the shelf and how to find other books like it.
All call numbers start with a letter of the alphabet, which tells us the general subject of the book. For example, B is for biography, C is for composer, and E is for history of the Americas.
After the letter, you’ll usually see a number. This number tells us if the book is part of a series (1, 2, 3) or if it’s about a specific subject (85).
You might also see some symbols and letters after the number. These symbols and letters tell us more about the book’s subject. For example, .B36 means that the book is about British literature and .F76 means that it’s about American history.
How can I use call numbers to find books?
Call numbers are numbers assigned to books and other materials that indicate where those materials are located on the shelves in the library. The call number is usually found on a label near the bottom of the spine of the book.
To find a book, look up the call number in the library catalogue or on the spine labels on the shelves. The shelves are usually arranged in alphabetical order by call number, so you can browse for books with similar call numbers.

How do I read a call number?
Call numbers are a system for organizing books on shelves. The number is like an address, and tells you where to find the book on the shelf.
Most call numbers in libraries follow the “Library of Congress Classification” system. This system groups books by subject. The first letter(s) of the call number tell you the general subject area of the book.
For example, “B” is for books about religion, “C” is for books about history, “F” is for books about North America, “G” is saved for books about geography, and so on.
After the first letter(s), you’ll usually see a decimal point followed by more numbers and letters. These numbers and letters divide the subject areas into smaller and smaller pieces, like a puzzle. They help to be more specific about what the book is about.
What are the different types of call numbers?
There are different types of call numbers, but the most common are Library of Congress (LC) and Dewey Decimal (DDC) numbers. LC numbers are used mainly in academic and research libraries, while DDC numbers are used in public and school libraries.
How are call numbers organized?
Call numbers are the unique codes that identify where a book is shelved in the library. These codes are usually a combination of letters and numbers, and they are assigned to books based on their subject matter. Each code corresponds to a specific location on the shelf, so finding a book with a call number is simply a matter of knowing where to look.
The first step in locate a book with a call number is to understand how these codes are organized. Call numbers are typically arranged in one of two ways: by Library of Congress Classification (LCC) or Dewey Decimal Classification (DDC). Both systems use a specific notation to indicate where a book should be shelved, but the two notations are not interchangeable.
Once you know which system is being used, you can begin to decipher the code itself. In general, call numbers are arranged from most specific to least specific, so the first part of the code will tell you what the book is about while the last part will be more general. For example, in the LCC system, “B” indicates books about philosophy, religion, and psychology while “P” designates books about language and literature. A call number that starts with “B” will always be shelved before one that starts with “P” regardless of what comes after those letters.
What are the benefits of using call numbers?
There are many benefits to using call numbers when looking for books. Call numbers help you to find books on the same topic that are shelved together. This makes it easier to find related materials. Additionally, call numbers can help you to locate specific editions of a book.
How can I learn more about call numbers?
Many people are unsure what a call number on a book is, or how to read one. A call number is simply a code that cataloguers use to organise books on shelves, and it looks like this:
The first thing you need to know about call numbers is that they are read from left to right. So, in the example above, the book would be shelved under ‘F’ for Fiction, ‘R’ for Romance, and ‘H’ for Historical.
The next thing to notice is that there are numbers interspersed between the letters. These numbers are called classmarks, and they indicate which shelf the book should be shelved on. In the example above, the classmark is ‘80’, so the book would go on the 80th shelf in the Fiction section.
The last thing to note about call numbers is that they often have extra letters and numbers at the end. These are called Cutter Numbers, and they indicate which order the books should be shelved in. In the example above, the Cutter Number is ‘L67’, so this book would be shelved after all of the other books that have ‘L67’ as their Cutter Number.
What are some common call number mistakes?
There are a few common mistakes that people make when looking for books using call numbers. One is to assume that all books with the same call number will be shelved together. This is not always the case! Another mistake is to assume that the first letter of the call number corresponds to the section of the library where the book will be shelved. For example, Books with call numbers starting with “A” are not always shelved in the same section as books with call numbers starting with “B.” Finally, do not assume that all books with the same subject will have the same call number. For example, books about history can have call numbers that start with a variety of letters.
Where can I find call numbers for ebooks?
Ebooks generally don’t have call numbers. Call numbers are assigned to physical books so that they can be shelved in a library. Since ebooks don’t need to be shelved, they don’t generally have call numbers assigned to them.
