Title: 856 subfield u When Marc 245 subfield h is Present

Hi,

This patch pulls in the URL stored in the 856 field subfield u when the Marc 245 subfield h has been defined as "electronic resource". This common cataloging practice is fairly reliable way to determine if the urls in the 856 field are for the actual resource rather than something like a table of contents or publisher's summary.
