Dr. Gabriel Sanchez Spanish Studies

Please see link above. Again my husband's roots intermesh with my roots. I have a question that is probably better asked on this website as the author Dr. Gabriel Sanchez deals with Spanish history. Does anyone know about him? I am interested in his work on Felix O'Neill as Felix O'Neill is my maternal great great grandfather's name. On the link above is Dieciocho 23 2000 117-113. Does this refer to a book? If you read down he has many other works relating to Spain and New Spain, so thought I would share. Does anyone know how to purchase his works or any libraries that have his works besides the one in Belfast?
Thank you for any help.
