I couldn't find any other bugs mentioning this, and I'm not sure if this should be multiple bugs, but there are a few things we'd like the option to change in the Card Preview for usability. We are trying to incorporate Z39.50 into all of our libraries' workflows more consistently and the ability to customize the Card Preview would be a huge help. 1. When using Card Preview to look at a Z39.50 result, the information there is pulling from specific MARC tags. For example, publication information is pulled from the 260, but most records we're looking at use a 264, so there is no publication information. 2. We aren't interested in some of the notes fields that are brought in, like Lexile and Accelerated Reader information, so we'd like the option to hide specific tags from the preview. 3. The subject headings are only pulling subfield $a, and we would like to see $v information also. 4. The subject headings are included in a string of text at the bottom of the card that we'd like to parse out/hide some of. Would it be possible to include any of this as an option in the framework settings?
