Learn tips for effective browsing, how brackets function, and how to find table numbers in WebDewey.

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
