Admins: MARC record handling for titles you’ve purchased AND have in a subscription collection

If you have a subscription collection and you purchase titles you have in that collection… will you get duplicate MARC records for the overlap titles?

  1. No, if you get your MARC records incrementally
  2. Yes, if you download each collection’s complete MARC record file

1. If you get your ebrary MARC records incrementally, then you will not get duplicate MARC records.  For example, if you:

a. Go to your ebrary MARC records page

b. Under Collections, click “Perpetual Access”

c. Click “Added MARCs” link for a particular dated/time-stamped line

You will get MARC records for all titles you’ve purchased (that you didn’t already have on your site) since the previous dated/time-stamped line.

Likewise, if you do the above but select the subscription collection, you will only get titles added to the subscription collection that you didn’t already have on your site (for example, as purchased titles) since the previous dated/time-stamped line.

2. If you get your complete MARC record file for Perpetual Access and for the subscription collection, each set will include titles even if they’re in the other set as well.  That is, you might get duplicates.  For example, if you:

a. Go to your ebrary MARC records page

b. Under Collections, click “Perpetual Access”

c. Click the “Download complete MARC record file” link

You will get MARC records for all purchased titles on your site (even if they are in other collections on your site as well)

Likewise, if you do the above but select the subscription collection, you will get all titles on your site in that subscription collection, regardless of whether you’ve also purchased them.

A trick to avoid duplication: When you download the complete MARC record file for a subscription collection, any titles you’ve also purchased will have a 980 field with the purchase details (titles you haven’t purchased won’t have a 980 field).  You can exclude all purchased titles by filtering out records with a 980 field.
