As I am having more free time, I thought I would start to write book reviews.  But before I start, I thought I should put down my views of what constitutes a personal numismatic library, in general terms to make it appropriate for all collectors, but using the titles of actual books in my library to illustrate the different categories of books.  I have over a thousand books in my library and more than 250 are numismatic or related to my numismatic areas of interest.
