If a user selects a 'Collection' (say Collection 'XXXX') by its Title or Thumbnail then a first page of Items making up that collection are displayed and at the top the user can click on 'Items in the XXXX Collection' to view ALL items in the collection, not just the first page.
If however the user clicks not on the Collection Title or Thumbnail but on 'View the items in XXXX' then all of the items in that Collection can be accessed, page by page.
The problem is that an inexperienced or new or casual user will not know or appreciate this subtle but very important difference and such a user is very likely to click on the Title and think that only those items displayed make up the entire collection.
I can think of no good reason for these two different behaviours which seem deeply unhelpful.
