Do not retain bibliographic data for the original in the following fields:
- 010 - LCCN
- 035 - System Number
- 040 - Cataloging Source
- 079 - Post-reclamation Master Record ID for the print version
Retain bibliographic data appropriate to the work being reproduced in the following areas:
- 245 - Title Area
- 250 - Edition Area
- 264 - Publication Area (re-tag to 264 _1 if the print record uses 260)
- 6XX - Subjects
- 7XX - Added Entries
- 4XX/830 - Series
Verify that the subjects are authorized. Provide additional bibliographic data for the e-book, as instructed below.
In some examples, an 856 link is provided. Follow the link provided in the 856 field to examine the resource being described. The text <URL> is used in place of the URL that would appear in the record.
020 - ISBN
Replace the print ISBN with the e-ISBN. Add the ISBN for the print version in a second 020 in ‡z if the publisher has included the print ISBN on the e-monograph. If it is unclear whether the ISBN applies to the e-version or the print-version, enter the ISBN in ‡a. The following example is from a vendor-supplied record derived from OCLC. The vendor stripped off the 13-digit ISBN but retained the qualifier for the 10 digit number; the retention of the form qualifier should be sufficient verification that the number should be entered in 020 ‡a.

040 - Cataloging Source
The cataloger should replace the data in the 040 as indicated in the example. Use a macro to ensure accuracy.
As far as the utilities and our statistics are concerned, variant edition cataloging is original cataloging.
