    About this concordance

    Sources

    Composition years and first-publication venues are taken from the chronologies and bibliographies at The H. P. Lovecraft Archive, maintained by Donovan K. Loucks. Each story card links to its corresponding page on that archive. The original tales are in the public domain and many are also available from Project Gutenberg.

    Scope

    The concordance is restricted to Lovecraft's solo-authored core Mythos fiction. The Dreamlands cycle (e.g. The Dream-Quest of Unknown Kadath) and ghost-written revisions (e.g. The Mound, Out of the Aeons) are excluded, even though they overlap thematically. The Case of Charles Dexter Ward is included as a Mythos-adjacent novel that names Yog-Sothoth and uses Necronomicon-lineage texts; its first appearance was posthumous (Weird Tales, May–July 1941, abridged).

    Caveats

    • Composition months follow S. T. Joshi's chronology where the archive cites it; precise day-level dates are rarely recoverable.
    • The Shadow over Innsmouth was first issued as a 1936 Visionary Publishing chapbook — Lovecraft's only book-length lifetime publication.
    • Entity tags reflect on-page presence or material plot use, not every passing reference. Mentions are noted in each card's footnote.
    • Plot summaries are paraphrased; quoted phrases (e.g. "blasted heath", "stars are right") are Lovecraft's own.
