In the last years of his life, Henry David Thoreau created something new. Part blueprint for a major new work, part scientific chart, and part re-envisioning of the way we experience the passage of time, Thoreau’s Kalendar was more a tool than a text. Comprised of six multipage charts of “general phenomena,” the Kalendar was an instrument for recording not just natural and weather-related phenomena, but also the hidden relations among them—between the skies of one June and the skies of past and future Junes—relations we often feel but can’t quite hold, rooted as we typically are in our own brief moment of linear time. Combining reproductions of Thoreau’s hand-drawn charts with transcriptions of the Kalendar ’s text and essays by acclaimed poet and scholar Kristen Case, this gorgeously crafted volume illuminates the final project of one of America’s most treasured writers and naturalists and offers a timeless, transformative vision of how to live harmoniously with the living world around us.","forthcoming":false,"isbn13":"9781571311597","publication_date":"20251121","publisher":"Milkweed Editions","slug":"henry-david-thoreau-s-kalendar","subtitle":"Charts and Observations of Natural Phenomena","title":"Henry David Thoreau's Kalendar"},"discovery":{"categories":{"all":[{"bisac_code":"NAT045040","confidence_band":"medium","label":"Wilderness & Wild Places","score":0.7083,"source":"bisac_hint_model"},{"bisac_code":"LIT024040","confidence_band":"medium","label":"19th-Century Literary Criticism","score":0.6905,"source":"bisac_hint_model"},{"bisac_code":"LIT025020","confidence_band":"medium","label":"Nature in Literature","score":0.6813,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"NAT045040","confidence_band":"medium","label":"Wilderness & Wild Places","score":0.7083,"source":"bisac_hint_model"},{"bisac_code":"LIT024040","confidence_band":"medium","label":"19th-Century Literary Criticism","score":0.6905,"source":"bisac_hint_model"},{"bisac_code":"LIT025020","confidence_band":"medium","label":"Nature in Literature","score":0.6813,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"LIT024040","confidence_band":"high","label":"19th-Century Literary Criticism","score":1,"source":"onix_publisher_code"},{"bisac_code":"PHI045000","confidence_band":"high","label":"Movements / Transcendentalism","score":1,"source":"onix_publisher_code"},{"bisac_code":"POL042040","confidence_band":"high","label":"Radical Politics","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Wilderness & Wild Places","score":0.7083,"slug":"wilderness-wild-places"},{"label":"19th-Century Literary Criticism","score":0.6905,"slug":"19th-century-literary-criticism"},{"label":"Nature in Literature","score":0.6813,"slug":"nature-in-literature"}],"reader_fit":["Good for readers who enjoy Wilderness & Wild Places","Good for readers interested in civil rights","Good for readers who enjoy Wilderness & Wild Places and 19th-Century Literary Criticism."],"related_lists":[],"series":null,"similar_books":[{"authors":["John MacNeill Miller"],"book_id":"9780813951782","cover_image_url":"https://img.bookfrontier.com/9780813951782.jpg?v=20260418T080002Z-pairingsrefresh%3A2026-04-18T08%3A00%3A02Z","score":13.0088,"title":"The Ecological Plot","url":"https://bookfrontier.com/books/9780813951782"},{"authors":["Alexandra Manglis","Kristen Case","Fred Moten"],"book_id":"9781571313775","cover_image_url":"https://img.bookfrontier.com/9781571313775.jpg?v=20260418T080002Z-pairingsrefresh%3A2026-04-18T08%3A00%3A02Z","score":10.0024,"title":"21 19","url":"https://bookfrontier.com/books/9781571313775"},{"authors":["Lyanda Lynn Haupt"],"book_id":"9780316426480","cover_image_url":"https://img.bookfrontier.com/9780316426480.jpg?v=20260418T080002Z-pairingsrefresh%3A2026-04-18T08%3A00%3A02Z","score":9.8681,"title":"Rooted","url":"https://bookfrontier.com/books/9780316426480"},{"authors":["John Hanson Mitchell"],"book_id":"9781625348708","cover_image_url":"https://img.bookfrontier.com/9781625348708.jpg?v=20260418T080002Z-pairingsrefresh%3A2026-04-18T08%3A00%3A02Z","score":9.8615,"title":"The Garden at the End of Time","url":"https://bookfrontier.com/books/9781625348708"},{"authors":["David Hinton"],"book_id":"9781645471479","cover_image_url":"https://img.bookfrontier.com/9781645471479.jpg?v=20260418T080002Z-pairingsrefresh%3A2026-04-18T08%3A00%3A02Z","score":9.8561,"title":"Wild Mind, Wild Earth","url":"https://bookfrontier.com/books/9781645471479"},{"authors":["Kathryn Gillespie"],"book_id":"9781478032861","cover_image_url":"https://img.bookfrontier.com/9781478032861.jpg?v=20260418T080002Z-pairingsrefresh%3A2026-04-18T08%3A00%3A02Z","score":9.8042,"title":"The Sound of Feathers","url":"https://bookfrontier.com/books/9781478032861"},{"authors":["Robin Wall Kimmerer"],"book_id":"9781571313560","cover_image_url":"https://img.bookfrontier.com/9781571313560.jpg?v=20260418T080002Z-pairingsrefresh%3A2026-04-18T08%3A00%3A02Z","score":9.8014,"title":"Braiding Sweetgrass","url":"https://bookfrontier.com/books/9781571313560"},{"authors":["Elizabeth A.
