The goal of the IWST workshop series is to create and foster a forum around advancements of or experience in Smalltalk. The workshop welcomes contributions to all aspects, theoretical as well as practical, of Smalltalk-related topics.

This book constitutes the thoroughly refereed post-proceedings of the 14th International Smalltalk Conference, ISC 2006, held in Prague, Czech Republic in September 2006. Being a live forum on cutting edge software technologies, the conference attracted researchers and professionals from both academia and industry that produced papers covering topics from foundational issues to advanced applications.

The 14th International Smalltalk Conference took place in the?rst week of September 2006 in Prague, Czech Republic. This volume contains the pe- reviewed technical papers that were presented during the academic track of the conference. The International Smalltalk Conference evolvedout of the annual meeting of the European Smalltalk User Group (ESUG). This meeting usually lasts about a week and allows Smalltalk experts to discuss Smalltalk solutions and envir- ments. The meeting attracts a diverse audience consisting of Smalltalkers from industry as well as from academia. Thanks to the perpetual e?ort of people like St́ ephane Ducasse, Noury Bouraqadi, Serge Stinckwich and Roel Wuyts, over the years the ESUG meeting was provided with a separate academic research track during which researchers could present academic results about Smalltalk and its development tools. Unfortunately, no formal publication forum was - sociated with this track, which made it less attractive for authors to submit a paper. Starting with this edition of the conference, we hope this will change. An agreement was reached with Springer to publish a post-conference proceedings of this 14th edition. I think our community owes a big thank you to St́ ephane for this! Hopefully next year this agreement can evolve into a 15th edition of the conference with formally announced proceedings. This will certainly motivate more Smalltalk researchers to submit a paper! The conference accepted just over half of the submissions.
