Hi Rachel,
The Toolkit does include references to field 511 in the bibliographic format. However, the Toolkit mappings no longer include the English language labels for MARC 21 fields, only their numeric designations. If you conduct an search for "Bibliographic 511" in the Toolkit Search box, then you will retrieve 106 results for elements which align to field 511 in the bibliographic format.
You're right to say that no mapping currently exists for the MARC 21 880 field in the Toolkit. The process of providing mapping alignments from RDA elements in the current Toolkit to MARC 21 is still ongoing. If the 880 field is not considered to be out of scope, then mappings to 880 may be added in the future.
I hope this helps.
Best wishes,
Thurstan
