The best place to start searching for Children's books is in the Library Collection.
We suggest you start with a Keyword search in Library Search.
Adding a capital AND and the word "juvenile" to a topic can narrow the search effectively as well. (ie. algebra AND juvenile)
** Make sure you use the "expand my results" to see books available from other libraries that can be requested.
** When searching for a particular book, placing the title in quotes can help.
Using the Collections Facet in combination with a subject is also effective.
