I had zero idea the "i" information icon was even clickable until a coworker told me it was. The icon is too small, not intuitive and blends in with other parts of the page. This is an accessibility issue for sure.

The 'i' information icon is very small, and does not stand out as a clickable object. Some people with physical impairments have difficulty clicking on small objects. The minimum requirement in WCAG for a target is 24x24 pixels at the minimum (https://www.w3.org/WAI/WCAG22/Understanding/target-size-minimum.html). Increasing the size and visibility of the information icon will help improve functionality of the display for all users.

This is critical because:
It isn't accessible for people with sight problems or physical limitations that make clicking on such a small thing difficult
Also it is important because more information that Vega provides at this point is needed to ensure that what is returned is actually what the searcher is looking for. If you had: author/title/publisher/date of publication/ and what kind of material i.e. print, digital, DVD, streaming etc. returned in search results, the more information button wouldn't be as critical as it is now.

The simplicity and uniformity of the i tends to blend into the line of text, without being noticeably a link. A design change here would be beneficial to patrons.
