Minimum Conditions: in describing a universally applicable set of minimum conditions for a piece of poetry to qualify as renku, the essay seeks to distinguish the genre clearly from other forms of renga, from other schools of haikai renga, and from the multitude of loosely related forms of linked verse that have arisen in recent decades amongst English-language poets.

Occurrence and Recurrence: an extended article synthesising various aspects of the historic and contemporary understanding of the forces which govern variety and change in renku sequences of all styles and lengths. This piece seeks to provide a comprehensive counter to the ubiquitous fallacy described in the article 'On Backlink' which appears elsewhere in Renku Reckoner under the heading Link and Shift.

The Mechanics of the White Space: this essay outlines the fundamental conceptual changes to linked-verse pacing and structure wrought by the introduction of nioizuke - scent linking - changes which laid the ground for the sharply contracted sequences typical of contemporary renku.

What Price Kigo?: this piece goes beyond notions of correctness in order to to examine the actual function of seasonal reference in renku. It distinguishes between kisetsu - a profound sense of season - and kigo - a season word - relating them both to hon'i - poetic essence. It closes with the question of whether renku can be written without seasonal reference at all.
