	  Escape the Northern winter, come to ICLP'99!

I would like to personally invite you to attend the
16th International Conference on Logic Programming, in
Las Cruces, New Mexico, USA.  There are several reasons
why you should attend ICLP'99, some of which I would like
to point out to you:

     1. The program chair, Danny De Schreye, and the program 
	committee have assembled an excellent program that
	contains papers on diverse topics, ranging from theory to 
	applications. Listening to these papers will give
	you a chance to come abreast with state-of-the-art
	research in Logic Programming. We in the logic programming
	community believe that logic programming is an important
	area of research within Computer Science; attending the 
	16th ICLP'99 will give you the opportunity to meet the 
	dynamic researchers who are active in Logic Programming 
	as well as the chance to appreciate the potential and 
	versatility of the Logic Programming paradigm. There are 
	several satellite workshops that will also interest you.

     2. Special discount rates have been negotiated with the
	hotels. You can stay for as little as $25 per night
	in one of the (quite decent) conference hotels, provided 
	you pair up with someone. A message area has been provided 
	at the ICLP web-site where you can communicate with others
	to find a room-mate. The registration fee has been kept to
	the minimum possible. Just registering for ICLP
	allows you to attend any one of the 7 ICLP'99 satellite 
	workshop that, for the first time, are being held concurrently
	with the main program thanks to Danny's vision. 
	Special student registration rate has been provided, which 
	includes the conference proceedings as well as the Banquet.
	A few student scholarships are also available. Preference
	will be give to those students who are presenting a paper
	at ICLP or an ICLP-related event. Contact Prof. Veronical
	Dahl for details (veronica@cs.sfu.ca).

     3. The conference will be held in Las Cruces, a small desert 
	town in southern New Mexico; famous for its red and green 
	Chiles, hot New Mexican food, and its old western traditions. 
	Las Cruces and its surrounding areas have numerous tourist
	attractions, most of which are listed on the ICLP'99
	web-site. Possible 1/2, 1, 2 or 3 day trips are also
	shown. I hope that you will have the time to visit some
	of these attractions during your stay. The weather 
	in Las Cruces during the winter is quite mild. If you live 
	in the Northern latitudes, ICLP'99 gives a chance to escape 
	the winter in your homeland, at least for a few days.   

     4.	ICLP'99 is being colocated with the 5th International
	Conference on Logic Programming and Non-monotonic
	Reasoning (located in El Paso, just 40 miles away)
	as well as the 1999 Workshop on Natural Language
	Understanding and Logic Programming (located in Las
	Cruces). Special discounts are available if you 
	attend any one of these events together with ICLP'99.

     5.	A sightseeing trip is planned to the world renowned
	White Sands National Monument on Friday, Dec. 3rd.
	(visit the ICLP'99 web-site for more details).

Association for Logic Programming. The registration fee includes all 
coffee-breaks  on all days, the ICLP'99 proceedings and the banquet 
(lunches are not included). 

For those attending LPNMR in El Paso there is a special reduced registration 
rate. However, you will get this rate only if you register separately with 
LPNMR and pay their registration fee as well. The reduced registration rate 
includes the Banquet and the proceedings, and entitles you to attend 
ICLP'99 sessions and workshops on Monday (Nov 29), Tuesday (Nov 30) 
and Wednesday (Dec 1). 

Student registration rates include proceedings  of ICLP as well as the banquet.
