The reports of the two anonymous referees have now arrived for the reference article by Levesque, Pirri, and Reiter; the present Newsletter contains the referee reports in full. Both referees recommend that the article should be accepted, but both also suggest certain changes to it.

The article will therefore be accepted, but the authors are given the option of revising it, taking the recent discussion and the referees' comments into account.

We also have two more discussion items for the article: a remark by John McCarthy, and an answer by Graham White to Pat Hayes (who in turn wrote in response to Graham's earlier contribution in the discussion about the article by Levesque et al).

Both referee's reports were written before today's discussion, of course, and the report of Anonymous Referee 1 actually arrived several weeks ago.

Graham White has accepted the invitation to publish his article "Simulation, Ramification, and Linear Logic" in the April, 1999 issue of the News Journal on Reasoning about Actions and Change.

Camilla Schwind has contributed an extended summary of the article "Causality in Action Theories" that she submitted recently. The summary is in latex/postscript format and can be accessed as usual from the discussion page for her article.

The list of accepted papers for the NRAC workshop at this summer's IJCAI conference is also included in the present Newsletter.

Additional debate contributions have been received for the following article(s). Please click the title of the article to link to the interaction page, containing both new and old contributions to the discussion.
