Do you know about Daedalus Books? They are "the online discount book and music store selling thousands of quality bargain books and overstock CDs for the independent reader and listener."
Books, CDs and DVDs at up to 90% off! Gotta love that.
I don't hit pay dirt with every catalog, but the Spring Children's Catalog had all of these:
Two by Carolyn Marsden, $2.98 and $3.98
THE GOLD THREADED DRESS
Three by Lucy Cousins (future baby shower presents) for $2.49-$3.98
I didn't know there was a companion for MY LITTLE SISTER ATE ONE HARE! Very fun! MY LITTLE SISTER HUGGED AN APE $3.98
LITTLE RUTH REDDINGFORD by Hank Wesselman looks like a fun twist on Little Red Riding Hood. A must for my collection! $4.98
SONG OF THE WATER BOATMAN by Joyce Sidman $10.95. Okay, fine, not such a great price, but might as well since I found so many others...
I've wanted this book since the first time I saw it! A BOOK ABOUT DESIGN: COMPLICATED DOESN'T MAKE IT GOOD by Mark Gonyea $4.98
There are also three from the Smithsonian Odyssey Series that look good ($3.98 each): A GOLDEN AGE: The Golden Age of Radio; THE LAST RAIL: The Building of the Transcontinental Railroad; THAR SHE BLOWS! Whaling in the 1860s. And for $3.98, why not check out THE ESSENTIAL ATLAS OF TECHNOLOGY from 2002. The information on basic technology (wheels and pulleys and the like) shouldn't be outdated.
This is why my classroom is positively overflowing with books!
