ASSOCIATED EVENTS

There are two associated events which everyone is welcome to attend.

1. On Sunday 9th April, there is a meeting of the Lambda-calculus EC
Network from 9am--5pm. This meeting will consist of short informal
talks (20 minutes) on recent results. The talks will be chosen on a
``first-come first-served'' basis. No registration fee will be
charged, but we ask for a 20 pounds contribution to cover expenses.
There will be a drinks reception at the end of the meeting from
5--7pm.  The scientific sites of the Lambda-calculus Network are
Marseille, Cambridge, Chambery, Edinburgh, Lyons, Nijmegen, Paris,
Rome, Torino and Udine.

2. On 13th April, there is a meeting of the EC Jumelage ``Programming
Language Semantics and Program Logics'' from 9am--5pm: programme to be
announced. The cost will be 15 pounds to cover expenses.  The sites
of the Jumelage are Genova, Cambridge and Edinburgh.


REGISTRATION 

The full registration fee covers coffee breaks, conference dinner,
reception and proceedings, which will be published by Springer-Verlag
in the Lecture Notes in Computer Science series. The student rate does
not include the proceedings and the banquet.  The conference will take
place in the Reid Music Hall at Bristo Square, University of
Edinburgh.  The registration desk is open the evening before the
conference (5pm--7pm at King's Buildings) and at intervals during the
conference itself. Further instructions will be given with the
acknowledgment for your conference registration.  Early registration
and accommodation forms must be received by 10th March 1995.  All
cancellations received before 27th March 1995 will incur an
administration charge of 20 pounds, plus any accommodation charges
which are not recoverable.  No refunds can be made for cancellations
received after 27th March.  Substitutions may be made at any time.

There are additional expenses for the associated events: 20 pounds for
the Lambda-calculus meeting, and 15 pounds for the Jumelage meeting.

University of Edinburgh. This is 20 minutes walk from the Reid Hall,
the site of the conference. Please note that no accommodation is
available at Pollock Halls after Friday morning (14th April).  Note
that all accommodation must be paid for in advance. Any form without
the correct payment will be returned.  Accommodation is limited, and
applications will be dealt with in order of receipt.  While we will do
our best, accommodation cannot be guaranteed for applications received
after 10th March 1995.  Special arrangements may be possible for
participants planning to bring partners or family. However,
accommodation of this sort is limited, so please contact us early.


ACCOMMODATION BOOKING FORM 

Accommodation is available from Saturday 7th April to Friday 14th
April (not Friday night).  The cost of accommodation per night for one
person is 25 pounds. There is no student reduction on accommodation.
Please fill in the details below.  Note that all accommodation must be

VENUE

The TLCA'95 conference will be hosted by the University of Edinburgh
in April 1995. Organized by the Laboratory for Foundations of Computer
Science, the conference will be held in the Reid Music Hall at Bristo
Square on the University's main campus in Edinburgh's city centre.
Accommodation is available at nearby student residences.  Edinburgh,
the capital of Scotland and one of the world's most enchanting cities,
is located in the east of Scotland on the Firth of Forth, about 400
miles north of London. It is well served by transport: hourly flights
from London, and direct connections to many European cities; Glasgow
airport nearby has connections from many US cities.  Edinburgh offers
numerous places of interest including Edinburgh Castle, beautiful old
town houses, the Palace of Holyroodhouse, art galleries, museums, and
the Royal Botanic Gardens. Most of these places are within walking
distance of the city centre or are easily accessible using local
buses.  Weather in Scotland is in general unpredictable.  Temperatures
in spring can vary between 8 C and 20 C, and there is usually a light
breeze. You are best advised to bring several layers of clothing, as
well as a rainproof jacket or coat.

PAYMENTS 

Registration fees and accommodation should be paid by Eurocheque,
cheque or bankdraft (in UK pounds drawn on a British bank), or by
travellers cheques in UK pounds. We cannot accept bank transfers,
credit cards or cheques drawn on non-UK banks or in currencies other
than UK pounds. All payments must be sent in advance to the conference
address given above.


PUBLISHERS' EXHIBITIONS

There will be an exhibition by publishers during the conference. 
Please contact the conference address given above for information 
about exhibiting.
