If you are interested in looking for books here is an OhioLINK search I did in the book catalog. Here are the directions (middle box bottom of page) http://libguides.starkstate.edu/education for ordering books. Remember, books will take about 4 business days and they are sent to Kent Stark Campus where you can pick them up when available. If you are looking for articles then I would use this guide http://libguides.starkstate.edu/education left side of the page. Log into Education Research Complete if off campus. Set up your search for EBSCO full text and do a keyword search for art therapy and autism.
Please let me know if you need any additional assistance!!
