Yahoo Finance offers both close (adjusted for splits) and adjusted close (adjusted for splits and dividends). They don’t offer the raw, unadjusted close, but for most stocks it’s reasonably possible to reverse engineer the stock split adjustments as long as you don’t have to deal with dividends. Be aware, though, that a spin-off may be treated as a split even though it’s a different animal with different tax effects. I don’t know if you’ll be able to get data for discontinued listings from this source.

A large enough library may have newspapers with stock listings on microfilm or microfiche. That would be a fun project.
