The Earth Sciences & Map Library at U.C. Berkeley is sufficiently comprehensive that is can be used as a test-bed for secondary students to learn research skills.
This library contains inventories for national wetlands, earthquake, climate, and weather. It features special projects such as terrain modeling and simulations, a research ship for drilling experiments (drilling in general-not oil), photography labs, and global ecosystems. Rare maps as well as street level maps can be viewed. A list of electronic publications in every sub-topic in this field is provided. From this site all of the other libraries at the University can be accessed—whatever students are tackling.
