Book Tree in Normal Heights, San Diego, is a metaphysical and spiritual bookstore on Adams Avenue that doubles as an independent publishing house under the Book Tree Press imprint. Founded in 1994 by author and publisher Paul Tice, the operation began producing small-format booklets in Los Angeles before relocating to the San Diego area in 1996 and opening the retail storefront at 3316 Adams Ave in 2001. The 92116 shop has outlasted more than ten used and new bookstores that once lined this stretch of Adams Avenue, making it the last standing independent bookseller on the corridor. Inventory spans metaphysical philosophy, world religions, consciousness studies, and controversial non-fiction, with dedicated sections for Christianity, church history, Bibles, religious criticism, Eastern philosophy, and comparative mythology — a subject range that overlaps with the spiritual-supply catalog at The Divine Bubble Metaphysical Boutique & Healing Center further east on the avenue. The new and used book inventory includes many hard-to-find and out-of-print titles that do not appear in conventional distribution channels, and the product range extends to palm-wax candles, essential oils, crystal points, gemstones, tarot decks, and imported incense. Tice has authored multiple titles through the press, including works on human consciousness and religious textual analysis, and the company maintains a catalog of several hundred proprietary reprints of rare esoteric works assigned ISBN prefix 1-58509. The publishing arm distinguishes Book Tree from general-interest independents — whereas Verbatim Books in neighboring North Park stocks a rotating literary fiction and non-fiction selection, Book Tree produces its own metaphysical-press originals alongside the retail inventory. Walk-in customers can trade used books for store credit, and special-order searches for out-of-print titles run at no charge through Tice's dealer network.
