All four Pendleton books are available in reprint form (hardback or softbound) from Higginson Book Company. I've had a reprint of the 1st book (written about 1911) for several years. The other three copyrights recently expired so Higginson can now make them. I already got two of the others and just ordered the 4th one a couple of weeks ago. They all have a wealth of information in them about the New England Pendletons. Just google "Higginson books" and you should be able to find their site and then look in the genealogical area by the last name.
