Alright, I have a small problem. I am applying to graduate schools for my ph.d. My application is OK, decent grades, great writing sample, but there's this one credential that I definitely want to include but can't put on the online application. These days, the applications are all online, and for a lot of schools what you can't upload to the application, you can't mail in either, because they simply won't accept it. I wrote a book on skepticism and philosophical naturalism, and I am getting it published by an academic publisher, and I desperately want to include what I think is an important credential with my application. I don't just want to mention the book on my resume and in my personal statement, I actually want to send it. I can send it to a couple of places, but other places (that I want to get into) don't accept supplemental materials. I'm definitely not bragging or anything, because my book has a lot of flaws, but I think that if the admissions committee sees the actual book that will definitely have a psychological impact, and I want them to see it. How do I get around the problem with a few schools that they "won't accept supplemental materials" and (politely) get the actual physical book to the admissions committee?
