A Requiem for Astounding

published in 1964
This is Alva Rogers' history of Astounding Science Fiction from its birth until turned into Analog in 1960.

In a review of the book, Mike Resnick described it as "an issue-by-issue study of the golden days of John Campbell's Astounding, in which Rogers' less-than-scintillating prose is more than compensated for by his boundless enthusiasm. He imparts that sense of almost unbearable anticipation he — and so many other fans — felt while waiting for each new issue, the agony of not knowing the end of a Heinlein or van Vogt serial for weeks on end. It's a lovely, nostalgic book, one that demonstrates exactly what fannish enthusiasm is all about."
