User blog comment:Tin77/Stories that used to be on Suggested Reading?/@comment-25037895-20150508033610

The only way to find out the history of the categories a page has had, would be to search through the pasta's revision history. Click the arrow next to "Edit" then click "History". Then you can click "compare selected revisions" and from there, click "Older Edit" one by one and eventually you will find out when the page was added/removed from Suggested Reading.
