Help with name of reference book

[pfennig-cowboy]

Please excuse that I am posting in English.

I have this medal (or Siegespfennig?), for the "Das Befreiete Magdeburg Übergeben an Tauenzien d 23 Mai 1814"

There are many similar medals on Ma Shops like this one: (but none I found are exactly the same.)

https://www.ma-shops.de/hild/item.php?id=2390

And the catalog reference is "Sommer A 165/62". My question is, what book is "Sommer A"? And is there a list reference books somewhere, so I can find the name of the book myself?

I'll include a picture, because we all like to see coins, but my question is about the reference book or catalog.

thank you, Michael
