Our sponsor this week is Basher Books, a world of little books that bring big ideas to life in ingenious ways.

The last time they sponsored us, we got this unsolicited note from an Unshelved reader:

I’m so excited you featured the Basher Books—the kids in my elementary library love them and I can’t keep them on the shelves; I have them all and am putting this newest addition on my book order now. Anyone who can make the Periodic Tables interesting to fourth and fifth graders has my utmost respect and admiration!

High praise indeed. Sign up for their email newsletter and you could win a free set of books for your school or library!
