Not sure where to post issues with the site. A regular search view of a location like London, Ontario is different from clicking on the Related Subject London Ontario. The Related Subject does not show all the items.
@blossomgirl is kind of a Bug for everybody so moved it. Thanks for reporting this! Can you please give 1 or better 2 examples of items that do not show on the Subject page (we are talking about the London Ontario HRC?)
Closing this for now. Please post again if this happens (and add examples and ideally URLs).
