Q. I need articles and books about the social penetration model.

I was able to find some articles about this in ProQuest PowerSearch and Gale Academic OneFile.  In ProQuest PowerSearch, do a search for "social penetration" or "social penetration model".  I was able to retrieve some articles using both search terms.  In Gale Academic OneFile, doing a search for "social penetration theory" retrieved a number of articles to review.

The library has several eBooks on the subject of interpersonal processes.  To access them, go to our catalog, OneSearch (link below) and search for interpersonal processes.  Click on the full text link below the title to access the book.

We also have books on interpersonal communication, and some of them may mention the social penetration model. You can find them in OneSearch as well by doing a search for interpersonal communication.
