Dear Colleagues:
A web site has been established to enhance awareness of new developments in
the area of item response models for unfolding responses to traditional
attitude questionnaires. The site contains current psychometric references,
newly released (free and downloadable) software for estimating parameters in a
particular model (i.e., the graded unfolding model), and illustrative data
sets produced from real administrations of attitude questionnaires. Please
stop by the site and let us know what you think:

We hope to expand the site offerings over time. Your comments about and
contributions to the site will be most welcomed.
Best Wishes,
Jim Roberts
