I put an illiad request in for the dissertation: Pascarella, C. B. (2013). Play therapy training among school psychology, social work, and school
Sorry for the confusion.
The cancellation that you received stated that the dissertation is available in hard copy in Herrick Library.
The call number is RJ505.P6 P36 2012 (General Collection).
After doing a quick search right now, I see that it's also available online here.
Let us know if you have further questions.
