To read a call number, look at each part separately. Read from left to right and top to bottom. Let's look at the number E645 .H37 2021 for the book titled: Monumental Harm: Reckoning with Jim Crow Era Confederate Monuments by Hartley.
E645
.H37

Line 2
After the letter(s), books are ordered numerically. Numbers are treated as whole numbers. 645 is read as a whole number. For example, 645 numerically comes after 641 and before 675.

Line 3
This starts with a letter organized in alphabetical order, followed by a number read as a decimal, NOT as a whole number.
So .H37 will come after H211 (since .211 becomes before .37) and before H4 (since .37 comes before .4).
