I can conclude that this copy of the book is very rare. I could not find any copies online for sale. However, I did find a few copies that are held in library collections or universities. There is a copy held in the rare books section of Newnham College library, which is outlined here: http://backfromthestacks.blogspot.ca/2012/05/katherine-philips-matchless-orinda.html, as well as a copy at the J. Willard Marriott library at the University of Utah, where they have made available a complete photo album of each page, as outlined here: https://collections.lib.utah.edu/details?id=86856.
