The Wheeler-Minot Farmhouse, also known as the Thoreau Farm or the Henry David Thoreau Birthplace, is an historic house at 341 Virginia Road in Concord, Massachusetts, United States.
 It is significant as the birthplace of writer Henry David Thoreau.
 The house was listed on the National Register of Historic Places in 2004.
 It currently serves as a museum and is open to the public.
The Walden Woods Project (WWP) is a nonprofit organisation located in Lincoln, Massachusetts, devoted to the legacy of Henry David Thoreau and the preservation of Walden Woods.
 It was founded in 1990 by recording artist Don Henley to prevent two development projects in Walden Woods, the forest around Walden Pond that spans Lincoln and Concord, Massachusetts.
 Its mission has since expanded from conservation to research and education on the works of Henry David Thoreau.
 In 1998 the Thoreau Institute at Walden Woods was founded as part of the Project; today its library houses a collection of Thoreau-related resources.
The Machine in the Garden: Technology and the Pastoral Ideal in America is a 1964 work of literary criticism written by Leo Marx and published by Oxford University Press.
 The title of the book refers to a trope in American literature representing the interruption of pastoral scenery by technology due to the industrialization of America during the 19th and 20th century.
 For example, the trope notably appears in Henry David Thoreau's "Walden" (1854) when the whistling sound of a steam locomotive disrupts the natural landscape of Walden Pond.
 Marx uses this literary metaphor to illustrate the relationship between culture and technology in the United States as depicted in the work of American authors such as Herman Melville, Ralph Waldo Emerson, Nathaniel Hawthorne, Henry David Thoreau, Mark Twain, Frank Norris, Henry Adams, Henry James, and F. Scott Fitzgerald.
Walden Pond is a lake in Concord, Massachusetts in the United States.
 A famous example of a kettle hole, it was formed by retreating glaciers 10,000–12,000 years ago.
 The pond is protected as part of Walden Pond State Reservation, a 335 acre state park and recreation site managed by the Massachusetts Department of Conservation and Recreation.
 The reservation was designated a National Historic Landmark in 1962 for its association with the writer Henry David Thoreau (1817–62), whose two years living in a cabin on its shore provided the foundation for his most famous work, "Walden; or, Life in the Woods".
The Great War and Modern Memory is a book of literary criticism written by Paul Fussell and published in 1975 by Oxford University Press.
 It describes the literary responses by English participants in World War I to their experiences of combat, particularly in trench warfare.
 The perceived futility and insanity of this conduct became, for many gifted Englishmen of their generation, a metaphor for life.
 Fussell describes how the collective experience of the "Great War" was correlated with, and to some extent underlain by, an enduring shift in the aesthetic perceptions of individuals, from the tropes of Romanticism that had guided young adults before the war, to the harsher themes that came to be dominant during the war and after.
A Week on the Concord and Merrimack Rivers (1849) is a book by Henry David Thoreau (1817–1862).
 It is ostensibly the narrative of a boat trip from Concord, Massachusetts to Concord, New Hampshire, and back, that Thoreau took with his brother John in 1839.
 John died of tetanus in 1842 and Thoreau wrote the book, in part, as a tribute to his memory.
The Thoreau Society is a literary society devoted to the works of Henry David Thoreau, it is based in Concord, Massachusetts, USA.
 Established in 1941, it has long contributed to the dissemination of knowledge about Henry David Thoreau by collecting books, manuscripts, and artifacts relating to Thoreau and his contemporaries, by encouraging the use of its collections, and by publishing articles in two Society periodicals.
Walking, or sometimes referred to as "The Wild", is a lecture by Henry David Thoreau first delivered at the Concord Lyceum on April 23, 1851.
 It was written between 1851 and 1860, but parts were extracted from his earlier journals.
 Thoreau read the piece a total of ten times, more than any other of his lectures.
 "Walking" was first published as an essay in the "Atlantic Monthly" after his death in 1862.
 He considered it one of his seminal works, so much so, that he once wrote of the lecture, "I regard this as a sort of introduction to all that I may write hereafter."
 Walking is a Transcendental essay in which Thoreau talks about the importance of nature to mankind, and how people cannot survive without nature, physically, mentally, and spiritually, yet we seem to be spending more and more time entrenched by society.
 For Thoreau walking is a self-reflective spiritual act that occurs only when you are away from society, that allows you to learn about who you are, and find other aspects of yourself that have been chipped away by society.
 "Walking" is an important canon in the transcendental movement that would lay the foundation for his best known work, "Walden".
 Along with Ralph Waldo Emerson's "Nature", and George Perkins Marsh's "Man and Nature", it has become one of the most important essays in the environmental movement.
Jeffrey S. Cramer (born 1955) is the Curator of Collections at the Thoreau Institute at Walden Woods Library, managing the collections of the Walden Woods Project, the Thoreau Society, and the Ralph Waldo Emerson Society.
 He has edited many books about the works of such American literary figures as Ralph Waldo Emerson, Henry David Thoreau, and Robert Frost.
Reform and the Reformers is an essay written by Henry David Thoreau.
 The essay was never published in his lifetime, and has been cobbled together from existing lecture notes that Thoreau himself picked over for his other writings, such as "Walden" and "A Week on the Concord and Merrimack Rivers".
