The book of letters is an interesting cross-section of Sandburg material, but I have to say that in my experience going through the correspondence I've seen, Herbert Mitgang made some interesting selections. He only included one uninteresting letter from Randall, although there were a number which could have better shown the relationship between the men, and really didn't include as many between Sandburg and his wife which I think are interesting. Of course, however, he was constrained by the space he had available. Harry Golden's biography was an interesting read, if a bit uneven. Hope you enjoy both books!

Abraham Lincoln is the only man, dead or alive, with whom I could have spent five years without one hour of boredom.
