Wooley wasn't the first to reprint Dan Turner. That honor, as far as I know, goes to Tony Goodstone, in his 1970 extravaganza The Pulps (a book that belongs in every library). Another story appeared in a 1977 Barnes and Noble special called Pulp Fictions.
But Wooley's book was (I think) the first Hollywood Detective collection, and is still one of the best. The hardcover edition (complete with dj) is a very handsome volume, featuring seven stories scanned directly from Spicy Detective, Hollywood Detective, Speed Detective and Private Detective Stories - including all the illustrations. This is the way Dan's adventures were meant to be read.
For those keeping score, the tales contained are: Homicide Highball; Off-Stage Murder; Dark Star of Death; Homicide Spike; Drunk, Disorderly and Dead; Hair of the Dog; and Dump the Jackpot.
