These aren't typical reading books, Leigh--they're biblical commentaries and theological reference books. If I list them on Amazon, they'll be much more likely to be found by those who would really like them.
There are some I might donate to a library or senior center, though, now that you mention it.
It's the series, The Story of Civilization, by Will and Ariel Durant, with eleven volumes. Fascinating, and loaded with unusual history and astute insights.
Thanks for suggesting it. At a library or senior center, it probably wouldn't matter at all that the individual volumes don't match.
