Rosenfeld Media is a relatively new publishing company focused specifically on producing books for the user experience industry. Their first publicaiton is forthcoming, and there are several others scheduled for publication through 2008. While the titles lean towards web and interface design, some of the publications will focus on widely applicable topics and techniques such as mental models and prototyping methods.
What's also interesting is that the company is "usability testing" their first book before publication. See Lou Rosenfeld's slide presentation on applying user experience to the publishing business.
