If you browse the "pen" tab of the various buildings, it will tell you what can be stored inside. The list is usually arranged in the following manner: 1st: A-Z current contents 2nd: A-Z currently/recently/soon-to-be available 3rd: A-Z no longer recent/soon-to-be available

Note that certain items (especially really old ones) may not show up in the pens unless you or one of your neighbors owns at least one of that item.
