Tip for effective browsing
Most search techniques (truncation, character masking, Boolean operators, grouping) cannot be used in browse queries. The browse term you enter is matched-—character by character, from left to right-—against the characters of the terms in the index.
Brackets in DDC numbers
- Browse results may include DDC numbers enclosed (or partially enclosed) in square brackets; for example, 331[.2109].
- Brackets indicate numbers or number segments that have been discontinued or relocated, or unassigned numbers.
- For discontinued/relocated numbers, notes in the record direct you to an appropriate class number.
- When searching or browsing for discontinued or relocated numbers, you may omit the square brackets from the query term.

Find table numbers
- To find a record for a DDC table number, you must enter 2 hyphens to separate the table number from the rest of the number.
- Type the table number (for example t1). Then type 2 hyphens ( --). Then type the remaining digits of the number you want (for example, 071). Do not type a space between the table number and the first hyphen, or between the second hyphen and the final digits of the number. Example: t1--071
