Just a couple of unrelated interestingnesses this morning.
I don't know anything about this image, other than I like it. And it would be a good image for a caption contest.
There's lots of it available on Etsy. I think it'd be fun to match the Dewey subject to the function of the piece - like, a ring magnifying 395.22.
Since I was traveling this week, I don't have a reference question today. But a fun post over on Closed Stacks can help hone reference skills.
Do you have any books on ____________?
and I'm able to immediately say, "yes, I'll show you where those are," and take them right to that subject in the stacks.
Afterwards, I explain why I could find them and how they can use the catalog to find books too, but the initial shock and surprise patrons show when you can seemingly pull a useful book out of thin air is too good to pass up.
Some patrons think I have every book in the library memorized. I try to convince them it's not magic, just organization, but many people still think locating information is beyond them. Maybe it means we need better signage.
