For younger kids, I'd start with Celebrate Halloween, part of National Geographic's Holidays Around the World series.
Holidays Around the World: Celebrate HalloweenWhat do you like doing around Halloween? Visiting pumpkin patches, carving jack-o'-lanterns, and telling scary stories? Dressing up in masks and costiumes, going to parties, and trick-or-treating for candy? We share many traditions with children throughout the world, but each culture has its own unique traditions. I liked learning the history behind this holiday and especially seeing how children in other places celebrate Halloween today. Children will definitely be drawn in by the vivid images - true to form, National Geographic excels in this area. The text is clear and reassuring, giving the message throughout that Halloween is a fun holiday for all to enjoy.

For slightly older readers, try looking at The Halloween Book of Facts and Fun. It delves into the history of Halloween traditions in a little more depth.
The Halloween Book of Facts and FunIn this informative book, Old delves into the history behind many of the traditions and stories we associate with Halloween. Children learn about how the original Celtic festival Samhain developed as a transition between summer and winter seasons. This fall festival then mixed first with Roman traditions and then Christian holidays. My daughter especially liked the story about how jack-o'-lanterns got their names from an old Irish tale. I found Old's descriptions clear and interesting, especially how Halloween became popular in the United States in the 1850s, after many Irish immigrated to America.
