Hmmm.... I've never considered my library a 'go to' place for this info.
Next time I'm there I'm going to check out what they have.
Actually, once those "in the know" among the general public figured out I was into guns, the questions just keep on coming - from info on a deceased relative's collection to an old rusty barrel someone found in a crawl space.
We're in a rural area, so it makes sense to have the info available - although I think I'm the only librarian in the county who's got a collection going, if only a budding one.
