In addition to the foregoing requirements, any clerk may include, or direct to be included, in any general index, such data as he shall deem proper. It shall be the duty of every clerk for whose office a general index has been provided, to make all proper entries in each general index in his office within a reasonable time after making the recordation to which the index entry pertains.
