Abstract
We at EHP continually strive to make our content more accessible to our readers. With this issue, we are pleased to unveil some journal format changes that we hope will help with this goal. Our Table of Contents has a new easier-to-read format. Titles are now in boldface, and keyword descriptors have been added. Research Articles for which nonspecialist summaries (Science Selections) have been prepared are identified as such with a small red arrow.
