My Hymnals - A collection, a hobby or an obsession?

I received 3 new hymnals in the mail yesterday and I was giddy with excitement. How many hymnals can one person own? No number is too high in my opinion, but I'm currently up to 7, and I can't wait for more!

What do I have, you ask?

Jewish:

Kol Zimroh, A Hymn Book - Cincinnati, OH 1885 (JUST GOT IT!)

Union Hymnal for Jewish Worship - 1914

The Service Hymnal - Philadelphia, PA 1922 (JUST GOT IT!)

Union Hymnal Songs and Prayers for Jewish Worship - 1940

Sabbath Eve Services and Hymns - New York, NY 1944 (JUST GOT IT!)

Union Hymnal Songs and Prayers for Jewish Worship - 1954

Episcopalian:

The Hymnal 1982 - New York, NY 1982

Currently on the look out for the 1897 Union Hymnal and Schirë jeschurun: Gesänge für den israelitischen Gottesdienst! Let me know if you see these!
