 only the part of the data in the specified field. Also record array
 scalars can be "indexed" this way.
 
+Indexing into a record array can also be done with a list of field names,
+*e.g.* ``x[['field-name1','field-name2']]``. Currently this returns a new
+array containing a copy of the values in the fields specified in the list.
+As of NumPy 1.7, returning a copy is being deprecated in favor of returning
+a view. A copy will continue to be returned for now, but a DeprecationWarning
+will be issued when writing to the copy. If you depend on the current
+behavior, then we suggest copying the returned array explicitly, i.e. use
+x[['field-name1','field-name2']].copy(). This will work with both past and
+future versions of NumPy.

 If the accessed field is a sub-array, the dimensions of the sub-array
 are appended to the shape of the result.
