Multicultural and Anti-bias Children's Literature

My school is adding Spanish for all students this year so we are searching for additional resources about Spanish culture and especially children's literature we want to have in the classrooms and library. Two good resources I came across are:
1) A checklist by the Anti-Defamation League on criteria for selecting books
http://adl.org/bibliography/

2) A  web site contains links to annotated bibliographies of children's multicultural books appropriate for the elementary grades (kindergarten through grade six). Cultural groups currently listed include: African Americans, Chinese Americans, Latino/Hispanic Americans, Japanese Americans, Jewish Americans,  Native Americans, and Korean Americans.
