The below will impact records we work with. An information session about using these codes, to be held in May, was also announced today; I'll send it after this message. Please consider attending.

Most BCP47 language tags are associated with 880 fields and their regular-field pairs. The Modern MARC documentation<https://urldefense.com/v3/__https://www.loc.gov/marc/ModernMARC-March2026.pdf__;!!IBzWLUs!UF64ML-xKZvxzYbjG8kzOFmPJOe1UsqrSLuAaQrIEBTQeenJoThNiYJjSjn1ZjMb0VESzt1eHSaKUtsZ4GU$> on the MARC Standards website<https://urldefense.com/v3/__https://www.loc.gov/marc/__;!!IBzWLUs!UF64ML-xKZvxzYbjG8kzOFmPJOe1UsqrSLuAaQrIEBTQeenJoThNiYJjSjn1ZjMb0VESzt1eHSaKYNrR24w$> has been updated to reflect this practice and provide more information about BCP47 codes and their use.
