In the Shadow of Goliath

In the Shadow of Goliath examines biblical texts, Second Temple traditions, ancient mysteries, and modern high-strangeness reports without reducing the subject to either "ancient aliens" or the claim that all "aliens" are demons.

Current Topic Focus

The library begins with historical books on angels and closely related spiritual beings, while also including works on Satan, demonology, biblical cosmology, ancient texts, and religious symbolism where they meet the directory's inclusion standards.

What's Next

Planned expansion includes the Nephilim, the Watchers, giants, alternative archaeology, ancient civilizations, UFOs and non-human intelligence, and related ancient-mysteries and unconventional-history subjects — without changing any existing book's URL. These categories are not yet populated; this section describes direction, not current inventory.

Methodology

Each entry requires: a verified historical publication event; the same underlying Work available through a verified current Amazon listing; historical and modern editions modeled as separate records; and editorial context describing the book's perspective and limitations.

FOR AUTHORS, RESEARCHERS, AND EXPERTS

xCited — Author Publicity and Authority Placement

Your Book Deserves More Than a Listing

xCited helps serious nonfiction authors, independent researchers, and experts turn a published book into a focused authority-building publicity campaign. We identify the podcasts, YouTube channels, newsletters, and media outlets whose audiences are already interested in your subject, develop compelling interview and story angles, conduct personalized outreach and follow-up, and help position you for appearances that can build readership, credibility, and long-term opportunity. Instead of paying for vague exposure or sending mass pitches into the void, you receive a campaign built around your book, expertise, message, and ideal audience.

xCited publicity services are separate from directory inclusion and editorial decisions.
