@ Corinna: The provided example is indeed meaningful and unsatisfactory, certainly source of confusion for the users! However, in the case of HathiTrust, I have got the impression that most of the time the journal title is followed by volume and year indications (like in https://babel.hathitrust.org/cgi/ls?field1=ocr;q1=cahiers%20de%20la%20documentation;a=srchls or https://babel.hathitrust.org/cgi/ls?field1=ocr;q1=journal%20of%20comparative%20literature;a=srchls). This is much clearer, although in contradiction with the traditional library cataloguing norms. I assume that in that same case, only records at the item level (with their handle) are harvested and integrated into PCI, and not records at the journal level. Since PCI currently includes 4 different HathiTrust collections (for US customers and non-US customers, records for material in the public domain, as well as material that is restricted due to copyright), I think it makes really sense to work at the item level. Beside the ‘Journal issue’ type, much more important for me is that Open Access HathiTrust collections only contain materials which customers and end-users may have access to… this is unfortunately not always the case (see #00175079)... :-(
