Ditto goes for album title searches. Limit title and artist searches to 20 letters. The title and artist fields in the catalog are limited to 20 letters or less to save space, and if you enter more letters than that, you'll get a 'not in the catalog' message. Or, You Can Browse The Alpabetical or Genre Listings. Be patient, because searching this way can take quite awhile.
Spelling is the key to a successful search.
If you aren't sure of the spelling, try entering just part of the name instead of the whole thing. For instance, say you are not sure how to spell Blues Traveler . If you enter Blues Traveller , you get nothing, but if you enter Blues Trav , you'll get the complete list for them. If the catalog number you have has less places in it, add leading zeroes until you have 7 places. You should end up with 10 digits, for example, 'SHA0005708'.
