Fellow Info-junkies,
  I have an extra CCI #27 (Real Time Programming/Embedded Sensors &
Storage) and an extra CCI #32 (Voice control of telescope, among other
articles). No labels. No torn, cut-up, or missing pages.

Would like to trade for CCI # 26, or CCI # 23, or CCI # 19 in same
condition (Labels OK).

I mail mine you mail yours mutual trust kinda thang OK?
You don't actually throw them away, do you?
