I'm not sure I fully understand all of your requirements, but if you want to replicate the "look" of your 2014 app, you could do the following
At the top level collection, create a single collection, and style cards and layout to match or look similar to your 2014 layout of the "Library" view. I will refer to this as the "Home" collection.
Make sure the HOME collection has setting "Collection Open Default" is set to "Browse View"
Do not add any additional collections to the Top Level Default collection except the HOME collection
Make sure the layout, grid size and cards use, best represent the "Library" view of DPS 2014
Create a collection to represent each FOLIO from 2014.
If you are using the migration tool, these will be created automatically.
Add the individual articles to that "folio" collection, in the same order they appeared in DPS 2014 folio
The Collection should be configured using a collection image that represents the cover art to represent the issue from DPS 2014
IMPORTANT: Make sure these collections have the setting "Collection Open Default" is set to "Content View"
I will refer to these collections as the "Folio" Collections
Add each of the FOLIO collections, to the HOME collections
When you set "Content view" as the Collection Open Default, it does not show a browse page (cards & grid). Instead, when you open the collection, it will automatically open to article 1, page 1 of the collection. Swiping right (or using navto commands) will move to the next article in the sequence.
You should have a hierarchy similar to below
default top level collection
HOME collection (using Browse view which will display a list of "folio" collections w/cards + grid)
Folio Collection 1 (using Content view)
Folio Collection 2 (using Content view)
Folio Collection 3 (using Content view)
Folio Collection ....etc (using Content view)
When you launch the app, the HOME collection will display first, then clicking into the "issues" folios will open those as it did in 2014.
Again, i'm not fully understanding your requirements, but hopefully this helps.
