Author’s Note, 2011
I wrote Barbary in 1986, when security at airports was less stringent than it is today. Will security at spaceports be equally stringent? I hope that won’t be necessary.
I considered revising the text, but once a writer begins revising a published book, there’s probably no stopping.
The book does include one correction from the first edition, replacing a change I originally made under protest. My editor was under the impression that nobody under 21 knows or ever uses any profanity. This isn’t true now and it wasn’t true then, so I changed it back.

Dr. John G. Cramer kindly gave me permission to reprint his Alternate View column, “Artificial Gravity: Which Way Is Up?” in the ebook edition of Barbary.
