Policy Justification: 



When Alliance catalogers find Network Zone records that lack ISBNs, the ISBNs should be added to the WorldCat master record.

Only add ISBNs to WorldCat with the piece in hand. Do not use other sources of information.

Generally add qualifiers to ISBNs to tell what they are for.

020 0435916602 (cased)

020 0435916610 (pbk.)

Add ISBNs for added volumes. (You may also need to update other elements in the record, such as contents notes.) Also include the set ISBN if it is on the piece.

020 0379005506

020 9780379005509

020 0379005514 (v. 1)

020 9780379005516 (v. 1)

020 0379005522 (v. 2)

020 9780379005523 (v. 2)

Add ISBNs for hardback or paperback to a WorldCat record for print when the hardback and paperback are cataloged on the same record. Refer to OCLC Bibliographic Formats and Standards “When to input a new record” for guidance on making this determination.

Do not add ISBNs for paperbacks to a record for hardback when the paperback is cataloged on a separate record, e.g. when the paperback has a different edition statement.

When transcribing ISBNs found on the piece, use 020 $z for e-ISBNs added to a bib record for print, and for print ISBNs added to a bib record for electronic. (This is in accordance with the LC-PCC policy statement for RDA 2.15.1.7.)

Do not delete ISBNs from WorldCat records.
