Usage examples of "compatibilities".

The spherical chamber, half a klick from wall to wall, was lined with every known variety of book produced by any sentient race anywhere in the galaxy: chips, memory rods, cassettes and tapes of various compatibilities, bound and jacketed hard and soft-cover publications, scrolls, folios, clay, wood, and bamboo tablets, stones, bones, hides stretched wide on wooden poles, clumps of knotted rope, and a good many other artifacts whose identity the young captain could only infer from their presence with those other objects he did recognize.
