   3. 028 Verify
   4. 100 Just verify that it's somewhere on the item.
   5. 300 Must include $a 1 audio disc : $b 33 1/3 rpm ; $c 12 in. ($a can be "sound disc" instead of "audio disc" ; $b might also include analog, mono, or stereo)
   6. 260 $a was not required when most of these were cataloged, so that doesn't affect the match.
   7. 505 Not necessary, but if you're deciding between two good records, pick the one with this field.
