The unique combination of Source and Taxon defines a Subject. Miners are invited to enter comments about the subject in a text box when choosing which Measurement Type to enter data for.
This field can be used for any kind of notes, but is especially useful in the following instances:
1) Where the measurements to be entered are secondary data, this box can be used to enter the original (primary) source (i.e. the citation listed in the secondary source).
2) If the authors indicate that comparable data from the same population is reported in a previous study (especially in behavioural studies).
