I am pleased to announce two new members in the International Federation of Classification Societies: the Section on Classification and Data Analysis of the Polish Statistical Society (SKAD) and the Portuguese Association for Classification and Data Analysis (CLAD). We welcome these new sister societies.

I am also pleased to announce that the Japanese Classification Society will go ahead with plans for the IFCS meeting in Kobe in March of 1996. The people of Kobe are recovering rapidly from the diaster of the earthquake and we wish them well.

DON'T PAY!!! the surcharge for hard copies of the Newsletter and Service with this year's dues. These charges will take effect only beginning with 1996. Please return the CSNA Services Information form attached to this Newsletter, if you did not do so last time. You should return the form whether you intend to use WWW or not. However, if you do plan to use the WWW access, and I hope you do, you need not return the form, if you will send your e-mail address to the Secretary, Dawn Iacobucci, at d- iacobucci@nwu.edu.

CSNA has a new address for its WWW homepage. Please access it with
http://www.pitt.edu/~csna/

Finally, Bernard Picton reminded me of an alternative WWW browser to mosaic: the Netscape Navigator, or just netscape. It is available for Mac, DOS, and Unix platforms. Bernard says,

"You might like to look at using Netscape instead of Mosaic as your browser. I've been following the computer press quite closely on this, and using Netscape since it became available in January. It's much faster and more reliable than Mosaic, in my opinion it really is way ahead.

Netscape have a web page at:
http://home.mcom.com/home/welcome.html

Version 1.0 is free for academic and non-profit users. 1.1 is only in beta at present, but has some good new features, including support for the next version of the html language, which will allow use of tables, etc. As far as I can find out, it's the only one supporting in-line JPEG images itself as yet as well. (Others need an external viewer for JPEG images, and can't display them in-line with text)."

One other point is that netscape is a smaller program and is therefore more likely to run successfully on machines with small RAM. Thanks Bernard.

The special feature in this Newsletter consists of some important information from our 'Webmaster', Stephen Hirtle. By the time you get this mailing, the current issue of the Newsletter should also be available on the Web. UPDATE: Sorry folks. I was a little late getting this out.

As the CSNA information officer, I would like to mention a few changes to the World Wide Web (WWW) pages of the CSNA. First and foremost, CSNA now has it own WWW address. The new address is
http://www.pitt.edu/~csna/csna.html

From this home page, you can access a number of classification-related services including several on-line bibliographies and the CSNA newsletters. The most recent additions are (1) the 1994 volume of the Classification Literature Automated Search Service, known as CLASS, and (2) the February 1995 issue of the CSNA newsletter.

If you have do not have access to web browser, such as Mosaic, Lynx, or Netscape, you can retrieve some of the information through an email server. To retrieve the CSNA WWW page via email, send a message to the address

"listserv@mail.w3.org" , with the single line of
send http://www.pitt.edu/~csna/csna.html

The hypertext document will be mailed back with you with hypertext links in brackets. You may request further documents by replying to the message with the numbers of the requested documents in the body of the message, e.g.,
2 3 14
You can also send the message 'help' to the listserv address above to learn more about this service.

I am also in the process of setting up a CSNA ftp server, where you can deposit technical reports, papers, or software code. Please let me know of any information, or pointers, that you would like to see on either the CSNA ftp server or CSNA WWW pages.

I will announce most changes to the CLASS-L, the classification listserv. If you do not subscribe to this listserv, you should consider doing so. It is a fairly low volume group, so it should not clog your mailbox with messages. To subscribe, send the two-line email message:
SUB CLASS-L Jane Doe (where "Jane Doe" is your name)
SET CLASS-L DIGEST
to the address: LISTSERV@CCVM.SUNYSB.EDU. The last line is optional, but recommended. This will set the digest option on, which means that you will get at most one message a day from the CLASS-L listserv, with all of the messages from that day bundled together as a single message. It will be identified with a subject heading "CLASS-L Digest", followed by the date. This helps in identifying incoming mail and reduces the number of email entries in your mailbox. It also virtually eliminates the chance of mistakenly replying to the entire list, when you mean to reply to the sender alone. (This last error has not been much a problem for CLASS-L, but seems to be a common occurrence on several other lists that I subscribe to).

Finally, I would like to include pointers to WWW pages of classification labs or classification researchers. If you have a home page, or your own classification depository on the WWW, and would like to make it available for others, please send me the address and I will include it in the upcoming list of classification labs.

::::::: Meeting Reminder :::::::

CSNA 95

See the previous newsletter for information about the program. Here is something about Denver, our host city.

CLIMATE: Denver in June is normally sunny, warm (85 degrees F) and dry during the day. Afternoon thundershowers are common, followed by clearing and cool weather in the evening (55 deg. F - 60 deg. F by morning). At 5300 feet above sea level, the humidity is low (30-35% in the day), and the sun is bright, so sunscreen is appropriate for outdoor activities.

TOURIST ATTRACTIONS: The conference hotel is in downtown Denver, within a 15 minute walk of the statehouse, the Denver Mint, the 16th St. shopping mall, the Denver Center for the Performing Arts, the Denver Art Museum, Coors Field (new home of the Colorado Rockies baseball club, unfortunately not scheduled to play on this weekend), and other historical places. Denver's Zoo, Museum of Natural History, and Botanical Gardens are a short bus or taxi ride away. Attractions within a drive of one to two hours include Pikes Peak, the Air Force Academy, Central City (slot machine gambling), Boulder, Estes Park, Rocky Mountain National Park, mountain resort areas at Keystone, Breckenridge, Copper Mountain Vail, and others. A variety of bus tours (including tours to Black Hawk and Central City) leave directly from the hotel. The hotel concierge can provide further information.

SPECIAL FEATURE: On Saturday, June 23 from 4:30 PM to 6:30 PM (approximately), a guided walking tour of historic lower downtown Denver ("LoDo") will leave from the hotel. Our guide will be Tom Noel, Professor of History at the University of Colorado at Denver, former chair of the Denver Landmark Preservation Commission, columnist for the Denver Post, and author of numerous books and articles about Denver and its history. The tour will include historic hotels and saloons, the former red light district, Colorado's "original" gaming district, Union Station, Coors Field, and some of the history associated with them.

LODGING: Participants will find in convenient to stay at the Executive Tower Inn, which is the location of the conference. A block of rooms has been reserved there until June 5 at the rate of $68 (single) or $78 (double). To make reservations, either call the Executive Tower Inn at 1- 800-525-6651 (1-303-571-0300 from abroad) , or notify them via FAX (303- 825-4301), and mention that you are attending the CSNA meetings to get the rates mentioned above. The address for written correspondence is 1405 Curtis Street, Denver, Colorado 80202 USA. All meeting rooms are handicapped - accessible. If you require a wheel-chair accessible sleeping room, be sure to request it specifically when making your reservation. Other hotels are available within a few blocks of the conference hotel, though they are generally more expensive. For information, please get in touch with the conference chair. Participants interested in sharing a room with another participant may inform the conference chair, who will provide names of others who are so interested.

TRAVEL ARRANGEMENTS

By automobile: Denver is located near the intersection of I-25 and I-70. Proceed south from this intersection on I-25 to the Speer Boulevard South Exit.(Exit 212A). Proceed towards downtown on Speer Boulevard, turn left for two short blocks on Lawrence St, right for two blocks on 14th St, and left on Curtis Street. The hotel is at the corner of 14th and Curtis Streets. Parking is available for $7/day in the hotel garage, with in-and- out privileges.

By train: AMTRAK leaves passengers at Denver's Union Station, 17th and Wynkoop Streets, about 10 blocks from the Executive Tower Inn at 14th and Curtis Streets. Taxis are normally available at Union Station.

By bus: Greyhound and Trailways leave passengers at the Denver Bus Center, 19th and Arapahoe Streets, about 6 blocks from the Executive Tower Inn. Taxis are normally available at the Denver Bus Center.

By Air: Denver International Airport (DIA) is located about 22 miles northeast of the downtown area. Planes arrive at one of three concourses, A, B, and C. Take the escalator down to the shuttle train to the terminal and baggage claim. The trains run every two minutes. At the terminal proceed up the escalator to level 5, and the ground transportation booths. The baggage claim is also on this level. Note that international arrivals (relatively few) discharge passengers directly at the terminal on level 5, without using the train. Ground transportation options include:

The city bus: Look for the "SkyRide" booth on level 5. Route AF takes you to Market Street Station, and 16th and Market Streets, about 5 blocks from the Executive Tower Inn. Fare is $6.00 each way, and exact change (or a ticket purchased at the booth) is required. Busses leave the West DIA Terminal outside door 506 at 45 minutes after the hour, from 6:45 AM to 12:45 AM (to 11:45 PM on Saturdays). The trip takes about one hour. There has been recent discussion about increasing the schedule.

Denver Airport Shuttle (DASH): DASH runs 10-passenger vans to downtown hotels, including the Executive Tower Inn, leaving DIA every 15 minutes until 10:30 PM. (Less frequently on weekends). Buy tickets ($15 one way, $27 round trip) at the DASH booth on level 5. Reservations are not specifically needed at DIA, but you should call for reservations two hours in advance of your return trip from the Executive Tower Inn back to DIA. To be sure of Handicapped-Accessible Vans, you should probably make a reservation at DIA, too. Phone: 1-800-525-3177 or (303) 342-5454. The trip takes 50-60 minutes.

Rental Car: All major rental car agencies are represented at DIA. Their booths are on level 5. Follow their instructions to I-70 west, then refer to the "by automobile" instructions above. Remember to leave extra time on returning your car to DIA, as the return lots are some distance from the terminal. Most agencies recommend returning your car 90 minutes in advance of your flight departure.

Taxi: Taxis are available at DIA, but the fare to downtown is expensive ($38 - $45 one way).

* JUNE 20-23, 1995: International Conference on Ordinal and Symbolic Data Analysis Organized by: INRIA Rocquencourt and TELECOM Paris. This conference is in the tradition of conferences previously held in Antibes (1990), and in Paris (1992) on Numeric and symbolic data analysis, and in Darmstadt (1992) and in Amherst (1993) on Ordinal data analysis. The ordinal and symbolic approaches to data analysis have been successfully developed during these years via stimulating workshops and conferences for experts in the field. Both approaches have particularly emphasized the intentional background of data which is necessary for validation, interpretation and communication.

Since many observed or experimental data sets are of symbolic or ordinal nature, it has become increasingly clear that ordinal and symbolic data analysis has applications in a large number of areas including medicine, biology, social sciences, economics, agronomy, data retrieval, information sciences. etc. Information: INRIA Rocquencourt - Conference Secretariat: Claudie Thenault, Relations Exterieures, Domain de Voluceau, BP 105 - 78135 Le Chesnay Cedex, France.
