Hi there, I'm a New Zealand librarian currently living in Mexico City. I recently started working for a company that sells e books and e book software to libraries in Latin America (the Overdrive software that Auckland City Libraries has). Part of my job is to create MARC records for the e books that the company sells via Overdrive. I'm relatively new to cataloguing, and as there are no other librarians here in the company, I'm wondering if someone on this list would be kind enough to help me with a query relating to the cataloguing of e books (more specifically field 533). I've searched the internet but can't find an exact answer to my question. If there is someone out there who has experience in cataloguing e books, and would be willing to help me with a (very brief!) question, (or can advise me who I might approach), I would love to hear from you at kinnes@librisite.com. Many thanks and warm regards from Mexico, Kate Innes Librisite de México, S.A. de C.V. Tel. 5272 6806 Email: kinnes@librisite.com
