You know about the Prague conference? http://www.dart-project.eu/achievements/project-conferences/prague-conference.html

I do now, thanks Ian.

OK. That means that I know how to use Scholar and you don't ?

Do you know how to limit google scholar searches to seminal works?

I am not sure if mr. tylor search and did home work before asking this question, the litratuer are full of information related to this question unless he asked specific question

Seminal = containing seeds of later development (i.e. cited).

So, since Google Scholar presents the most cited documents first, you should concentrate on the first page of returns. If you select the first document listed by Scholar, you can click to find the documents citing it. You can even repeat that process to go even further back in time!
