Number search

Definition

Any number that is part of a record's bibliographic information that you can use to retrieve the records you need. The system finds the number in an indexed field.

Index label format

xx: (where x represents an alphanumeric character)

Examples

• Dewey Class Number — dd:616
• LC Class Number — lc:z5074.g8

Notes

• Most efficient way to search for these types of numbers:
  • OCLC Control Number
  • LCCN
  • ISBN
  • ISSN
  • Dewey Decimal Class Number
  • LC Class Number
• A number search can retrieve a single record (e.g., by its unique ISBN) or precisely related records (e.g., by class number). Numbers are usually unique to a single record or group of related records.
• Type all numbers and letters.
• Omit spaces.
• Omit punctuation, except keep periods (.) in classification numbers.
• When entering ISBNs ending in x — If you use the number keypad, truncate the number using the asterisk key (*).
