Since the website contains scholarly articles, I suggest to submit the url to Scholar.google.com . It's actually a search engine based on Google for academic articles such as journals, proceedings, thesis and technical papers.
To submit your scholarly-content website, go to this URL, http://www.google.com/support/scholar/bin/request.py . Google scholar is getting popular to the academicians or researchers for their literature review and referrencing. Hence, I would say it's a wise to submit the website to such service.
