The sections below provide a finding aid and overview of the Dewey Decimal Classification System numbers at Grainger Engineering Library. For locations on the third floor, see the Library Map.
Dewey Decimal Finding Aid
expand
Follow these basic principles in reading Dewey Decimal call numbers:
- Any numerals that appear behind the decimal are read as decimal numbers. For example:
- 623.3 comes before
- 623.306 followed by
- 623.35 followed by
- 623.4 etc.
- When a number follows a letter, read it as in the following example. For example:
- 623.306 W72 comes before
- 623.306 W727 and would come before
- 623.306 W75 and before
- 623.306 W8
- A lower case letter may follow, adding another layer of alphabetical order.
Note: When there is no decimal point, items are shelved in this order:
- 623 W72
- 623.1 A12h
- 623.1 A8h
Note: Call numbers that begin with A, B, and C should be substituted with these numbers: A = 016., B = 920., and C = 380.
