The latest we've received in this series is vol. 49, 1999 (arrived April
2000).  Amazon.com has shown vol. 50, "The Future of Urban Environment"
for some time but keeps moving the publication date forward.  At the
moment it is set at Oct. 30, 2004.

I emailed Sage to ask about it and received an email response stating,
"There has been only vol. 49 published.  I do not think any other
volumes will be published."  I emailed back for confirmation - "Are you
saying publication has ceased?" and now am told, "Well, the last
publication was in 1999, so yes I can only assume we are no longer
publishing any more volumes."
Well, call me picky, (or call me a librarian) but that is not nearly as
precise nor as official as I would like.
Has anyone else information on this title?
TIA,
