2. MARC Language Notes and Codes
In bibliographic records, an entry for the Sorbian language in a 546 language note field is encouraged, especially for pointing out in which Sorbian language the publication is.
For older materials, mainly World War II or older, mostly the Fraktur typeface was used for prints. Such a note is usually added to the 546 field.
Examples (in MARC format):
AACR2 RDA
546 In Upper Sorbian ‡b (in Fraktur typeface) 546 Upper Sorbian; ‡b in Fraktur typeface.
546 In Lower Sorbian ‡b (in Fraktur typeface) 546 Lower Sorbian; ‡b in Fraktur typeface.
However, if the identification of the typeface does not end the field, then the tagging for the subfield is left off.
Examples (in MARC format):
546 Upper Sorbian (Fraktur typeface), with summary in German.
546 Lower Sorbian (Fraktur typeface), with summary in Upper Sorbian.
For Upper Sorbian, use the language code hsb, regardless of typeface.
For Lower Sorbian, use the language code dsb, regardless of typeface.
For mixed materials containing both Sorbian languages, or if in doubt, the language code wen is used, regardless of typeface.
To discern between the two Sorbian languages, please consult the chapter Distinguishing between Upper and Lower Sorbian.
