Dup Check vs. TitleMatch

Print Topic

TitleMatch checks the titles on your Mackin lists against your library catalog to see if there are any duplicates. TitleMatch also determines if you have the same title included on more than one list, whether that list has been submitted or unsubmitted.

Dup Check searches for duplicates at a much more granular level. You can use Dup Check to find exact duplicates on the same list you are currently viewing. It will also search for the same titles with different formats on a list. If you have the following Frankenstein items on your list:

Dup Check

Dup Check, if activated, will list the following items as duplicates:

Dup Check

Though they are all Frankenstein titles, only two versions of Frankenstein are designated as having duplicates: the version published by Oneworld Classics and the version published by Abdo Publishing Company. Each is an example of the same versions in different formats. The Oneworld Classics’ Frankenstein comes in both the MackinBound and Paperback formats, so that is considered an instance of duplicates. Separately, the Frankenstein: Single User put out by Abdo Publishing Company is another version of Frankenstein, which is offered in CD format. However, customers also have the option of buying the CD plus a hardbound copy. Therefore, Dup Check finds that the CD format is a duplicate of the CD plus BK (book) format.

Dup Check will find exact duplicates (e.g. two paperback copies of Frankenstein published by Oneworld Classics in 2008 on the same list). Additionally, Dup Check allows you to see if two or more items were included on the list that are essentially the same but with different bindings/formats. You may decide to deselect duplicates or keep them on your list.

NOTE: Upon request, Mackin will look for titles on your order that you may already have in your library. This is done by checking the ISBNs in your order against those from previous Mackin orders. If there is an exact match, that title will not be ordered and you will be notified. As you know, different publishers use different ISBNs, so we also check title and author for exact matches. If you would like to have us check your Mackin orders for duplication, call our Customer Service Department at 800.245.9540 or email customerservice@mackin.com.
