Denny, FYI. Sorry, the answer from ProQuest is of the "it's not a bug, it's a feature" variety... Looks like one can only link to the Basic screen for Star Trib in PQ News.
Q: When I go to the Star Tribune (archives via ProQuest Newsstand), it puts me in the Star Tribune in "basic" search mode, as expected. But when I then click on "Advanced" it throws me out of the Star Tribune-only to "Multiple Databases." Can this be fixed?
A. The reason you are experiencing this is [because] the Star Tribune is [a] subcategory of ProQuest Newsstand and thereby cannot be searched independently, unlike the Chicago Tribune which is its own category.
I would recommend performing an advanced search with ProQuest Newsstand as
the database selected.
Then click on the More Search Options link towards the bottom of the page.
The first empty field is for the publication title; if you use the hyperlink to look up the publication you can filter and select Star Tribune.
This will allow you to narrow your search to this publication.
