Where we live, there are libraries running under two separate library systems (i.e. no trading books back and forth). The big library downtown is under a different system from the library that's closer to us--the point being, we don't get to use that system as much because it's hard for us to get down there.
But when we do...we fully appreciate how much this library has held on to that other libraries either never had, or have discarded. (Even WITH the big booksales every year.) After the library sale yesterday, we went upstairs to the children's room and borrowed some of the books that we don't usually get to read.
The library closer to us has All of a Kind Family. The downtown library has all the sequels.
The library closer to us has The Moffats, Rufus M., and I think Ginger Pye (we just finished reading our own copy of that). (We're on an Eleanor Estes kick right now.) The downtown library has The Middle Moffat, The Moffat Museum, and Pinky Pye.
The downtown library has Rumer Godden's Miss Happiness and Miss Flower, and the sequel.
And so on.
How they've managed to hang onto all of this stuff, AND find room for The Tiara Club books (I'm not joking--I didn't even know there were such things), I don't know. But I'm grateful.
