Mark is dead-on right about the limited market.
In the case of Bahto's book, it was published in 2002 by a company (Clock Tower Press) that had a brief life. It closed in 2005. Some of its titles were bought by John Wiley & Sons. A check of Wiley's online catalog doesn't show Evangelist among those titles, and further, Wiley doesn't appear to have issued any golf books since 2012, though many previous titles are still available.
Clock Tower owned/owns the copyright to Evangelist, so anyone interested in reprinting it would need to buy that, but today, if Wiley doesn't own it, from whom? Even if that is accomplished, add in the logistical nightmare of reassembling the original art (presuming the original technical files used to print the book no longer exist), then designing the book a second time – either to duplicate or improve on the original – and it becomes a maddening task that is also unlikely to turn a profit.
In this case, ebay or Abe Books is your best friend. Be patient and one will turn up at a price favorable to you. It did for me in the case of James Finegan's impossible-to-find history of Philadelphia golf. Got one at original price and mint condition!
