About this index

Margin & Meridian is a quarterly of long-form field reporting on measurement, published from a converted lighthouse-keeper's cottage on the Fife coast. Each issue is set in a single typeface and printed in two inks.

The index is the magazine's front door. We deliberately withhold images from the list itself: a title should have to earn your attention on its own before the picture arrives.
