Here's a quick guide on how to read Library of Congress Call Numbers.
The first line is read in alphabetical order.
Read the second line in numerical order.
The third line is tricky. Read the letter in alphabetical order then the number as a decimal.
Sometimes the fourth line will look like this and you read it exactly like the other line.
When you see a line near the bottom that looks like a year, it is a year! This goes in numerical order.
You could think of a call number like a detailed address in reverse: planet, country, state, city, street, street number. Each line helps you narrow down the book's exact location!
