Fields include:
ColHabitatVerbatim
ColPlantDescription
PalDesDescription
MinIdentificationDescription
MinTextureStructure
MinIdentificationOther
As an example, there are a few hundred records with ColHabitatVerbatim containing multiple values in the EMu dump.
As an example of one on the Portal: https://data.nhm.ac.uk/object/dc94c336-957a-486d-911e-5f9fd2e5fba2.
These look like multiline strings so using:
combine_text(record.iter_all_values(emu_field))
is probably the best bet for all of these.
