All About EntryMate™ Conversion
$125 per thousand ISBN's converted. You only pay for the ISBN's that are found at the Library of Congress. However there is a $125 minimum charge. This entitles you to up to 1,000 ISBN's converted. Above that you pay 12.5 cents per ISBN found. Thus if you submit 500 ISBN's the cost is $125. If you submit 1,300 ISBN's and 900 are found, the cost is $125. If you submit 2,000 ISBN's and 1205 are found, the cost is $125 + (12.5 cents/ISBN X 205) = $125 + $25.63 = $150.63.
