We have a large network of libraries, often with different editions of the same title. Unfortunately on Leganto, there isn't anything that would alert students to other editions of the same work being available to them in another library (often a college library, in our case, or other faculty libraries). This option does appear, after a fashion, in Library view (Full details -> related items -> other versions). It would be very helpful for there to be an alert on a citation in student view which would let a student know that although edition X only has one copy, there could be other copies/editions they could consult. This is particularly useful for colleges, but also as often an instructor will put random editions on a list.
