Screenshots of the Arrowsmith web user interface that was employed by field testers during most of the two node searches described in this paper.

The raw B-list, containing 741 terms that are shared between the titles of the A and C literatures. (Note that only one paper in MEDLINE mentioned both retinal detachment and aortic aneurysm in the title.)
