==== Input Conventions ====
When records from CERL members are ingested into the CT they may not have sources in separate fields (such as 290 and 291). Examples for such a case are found in the ESTC records, where reference works and short titles of works, in which the name of a 2XX is occuring, are all filed in the same field. In this case the CT record will have all this information mapped to field [[290|290]].

==== Mapping ====
There is currently no mapping of this field's content to RDF.

==== Examples ====

  - 291 #1$aOoge-salf. / By A.T, 1663$sSTCN(ppn833466224)
