Need to find a book on a difficult subject?

See the Literature Database at Helping Books Connection. I'm always looking for new resources to help with reference questions, and this may prove to be a useful one. I particularly liked the ability to browse by subject. Unfortunately, it will take some exploration to discover which search terms work best for finding group by age or the like. But still, this could very well find it's way into my regular bag of tricks. For example some of the subject headings are: fairness, honesty, respect, adopted, step-parent, death, illness, bullies.
