Locating a book in Chalmers
After you've identified a book you're interested in, you'll need its Call Number in order to find it:

Call number breakdown
The call number for the book in the screenshot above is HQ1155 .S66 2010. This call number breaks down as follows:
- HQ represents the general subject area and is sorted in alphabetical order, e.g.,
G ⇒ HQ ⇒ J
HN ⇒ HQ ⇒ HS
- 1155 represents a specific subdomain or discipline and is sorted as a whole number, e.g.,
HQ310 ⇒ HQ1155 ⇒ HQ2100
HQ1140.9 ⇒ HQ1155 ⇒ HQ1155.1
- .S66 represents the author's last name or another identifier and is sorted alphabetically by letter and then numerically as a decimal, e.g.,
HQ1155 .R98 ⇒ HQ1155 .S66 ⇒ HQ1155 .T11
HQ1155 .S42 ⇒ HQ1155 .S66 ⇒ HQ1155 .S8
- 2010 is the year of publication but is not usually necessary for finding a book
Finding your book
- Use the one or two letters at the start of the call number (HQ in this example) to identify the book's general location in the library.
- Once in the general area, use the labels at the end of each shelf to find the row containing the initial letter/number combination (HQ1155 in this example).
- The initial letter/number combination (HQ1155) should narrow the search down to one or two shelves, where either the book's author and title or the decimal letter/number (.S66 in this example) can be used to identify the correct book
- If necessary, the date (2010 in this example) can be used to differentiate between editions or works by the same author
