The Hartley Library uses the Library of Congress classification scheme for subjects other than Education which uses Dewey Decimal Classification. Key locations for titles of interest to Chemistry students are listed here.
When you enter the details of the item that you want on the catalogue it will display a call number or code that tells you where the item is shelved.
The call number will usually look something like these examples:
TK 2380.45 GAR
B OCEAN (Physical) Kna
Although the codes look different, they work in much the same way: the combinations of letters and numbers gives a location based on the subject content of the item. The items are arranged on the shelves using the call numbers.
The library floor plan will show you where items with particular call numbers are stored
