Comment 3 for bug 2045150

Confirmed, the "Holdable" column displays true if the item, shelving location, and status are all marked holdable. (On the other hand, arguably the column could be labelled "Not Unholdable" since whether the item is actually holdable is dependent on hold policies that cannot be fully calculated without knowing for whom a potential hold is intended. Making that distinction fully clear in the UI could be challenging, though.)

By the way, is it entirely clear that "Item Table" is meant for circulation staff and "Holdings View" for technical services?

Regardless, I think it would also make sense to have both interfaces have columns available for each component of holdability (or OPAC visibility), possibly with different default displayed columns for each interface.
