Attractively produced hardback the size (& weight) of a brick. Insightful to have both sides (albeit inevitably partially) of a correspondence (as does the interesting C. L. Moore paperback volume) rather than (as is more usual, in part because he rarely kept other people's letters to him) only HPL's side of it; & a fascinating introduction that delves into things like Long's date of birth & why HPL got it wrong (subject of a lengthy historical disquisition!) & also discusses the considerable work that went into the assembling of this collection, which includes many letters never previously seen. As always with these Hippocampus Press publications the annotations are detailed, thorough & insightful.
