Science Fiction ISAAC ASIMOV ROBERT HEINLEIN Arthur Clarke PB Lot Of 8 Robots

Lot of 8 science fiction books by Isaac Asimov, Robert Heinlein, and Arthur Clarke. The Foundation Trilogy, Robots of Dawn, Robots in Time - Emperor, Robots in Time - Warrior, Caves of Steel, The Past Through Tomorrow, Grumbles From the Grave, and Tales From Planet Earth 2001 Anniversary Edition. Please read below for condition: Mostly good condition. One of the Heinlein books has a very worn cover. See photos for a few tears and one stain. The Arthur Clark book has many words underlined - not phrases or sentences - just words. The underlining is done in black ink so it is not too distracting. All binding is in good condition. Most of the older books have browning, but everything is readable. No other writing except for the Clarke book.
