The final volume of Princeton's Kierkegaard's Writings series, the Cumulative Index provides wide-ranging navigation to the preceding twenty-five volumes. Composed of over 90,000 entries, the Cumulative Index offers access to Kierkegaard's complex authorship and the extraordinary range of subjects he addressed in his writing. Covering the series' historical introductions, primary works, supplementary material (journal entries), and footnotes, the Cumulative Index provides a comprehensive entryway to more than 11,000 pages of text. Readers are able to survey via extended entries Kierkegaard's dual authorship, pseudonymous and signed; his numerous biblical allusions; his references to Christianity, God, and love; and his frequent use of analogies.

A cumulative collation of the extensive supplementary material is also included, giving researchers and avid readers the opportunity to cross-reference Kierkegaard's Writings with his journals and papers published elsewhere in both English and Danish.
