One of the kids at work is from Germany. Really nice kid.

I found a 1909 German Lutheran hymnal, at a used book store.

It’s in pretty decent shape, but the hard cover glue has separated some from the spine.

I’d like to have it fixed for her.

My mom worked at the local public library for my whole childhood. They had a very impressive book repair department.
You may check your local public library (especially if you’re in a smaller town) as they may be able to repair it for you.

You live in Miami? Any big city will have book repair businesses. Just look it up. That's what I did recently. The family tree book that's been around for decades, with things were falling apart (pages falling out, back cover separating from the spine). The repair took a week and was outstanding.
