Library Availability and electronic content
When electronic material records are pulled from the Library Catalogue, the $856 URL is extracted to become the URL of the resource in Talis. In the absence of Holdings data for these items, the Library Availability look-up is reported as unavailable. It might be preferable if the look-up script checked (against a set of rules) the presence of certain values in the Aspire record for the resource (such as a Web address or electronic resource format) and then not attempt the look-up, but instead present the end user a message such as: "This electronic material is available online. Access it via the Web Address in the item record".
We plan to include some general improvements to the library availability display, part of which will be to provide better information when the resource is an ebook or journal with an openURL link
