FAQs for BLII-12 Students

Q: How do I handle ambiguous subject headings in DDC?

Use the DDC Manual of Classification to resolve ambiguity by cross-referencing schedules (e.g., Table 1 for notational conflicts) and consulting the DDC Library of Congress supplements.

Q: Are there specific tools for validating MARC records?

Yes: Use Library of Congress MARC Editor or Koha’s MARC validation tools to check record integrity before submission.
