Where can I find out the value of my books?

Question

I would like to sell the following books...they are rare...

*The Poetical Works of Thomas Hood with Biographical Introduction by William Michael Rossetti, published by A.L. Burt, NY

It is a red hardcover. On the outside it says HOOD'S POEMS. There is not date on it though it has to be at least 90 years old.



*Whirligigs, by O. Henry. Published by Doubleday, Page and Company in 1910

This is a blue hardcover.



Let me know. Thanks. Brenda
