39 In order for this method to return the correct result, it must be

43 concatenating multiple such catalogs.

45 Additional Catalogs or sequences whose elements correspond in order to 

46 the records of self (i.e. ``zip(self, *args)`` is valid) will be 

47 subset using the same slice object used on self, and these subsets 

48 will be returned along with the subset of self.
