Not Just Any Library: My Library

Is it secret?  Is it safe!?
Years ago, I read an Anthony Monday book by John Bellairs—I think it was The Treasure of Alpheus Winterborn (excellent book, by the way). Bellairs had a line about Monday’s uncle who had an honest to goodness library, not just a room where someone put up a bookshelf.
That line may have cursed me.
When I learned that people could have their own library, I wanted one.
In our current house, we have a room designated as “the library”.  It is not an Anthony Monday...
