I wanted to know which publisher has put out the most Caldecott-winning books over the last 20 years, so I looked at the data.

But take these numbers with a grain of salt.

The totals were a bit difficult to compile, mostly due to the numerous acquisitions that have taken place in publishing over the last two decades. Harcourt, for example, had some Caldecott Honor/Medal wins before they joined Houghton Mifflin on 2007. I included those in the Houghton Mifflin Harcourt total, rather than giving Harcourt their own row.

For imprints, I attributed their Caldecott totals to the larger house they are affiliated with. Roaring Brook Press, for instance, has a number of Caldecott Honor/Medal winning books. I included those with the numbers for Macmillan.

Also something to consider – I don’t have the number of books published overall, so it could be that the houses at the top also put out the most books per year.

Here are the numbers I came up with (leave a comment if you see something I missed):

Anything jump out to you?
