BIG SKY (edited by Peter Young) are now available online.
Editor Peter Young writes, "Big Sky 3 and 4 are two parts of a special project released for Loncon 3. Both are concerned entirely with Gollancz’s 'SF Masterworks list' – every title has reviews and commentary, all listed in order of appearance."
I'm mentioning it here because I have a couple of Philip K Dick novel reviews in Big Sky 3:
1) PHILIP K. DICK, FLOW MY TEARS, THE POLICEMAN SAID
2) PHILIP K. DICK, A MAZE OF DEATH.
