The library recorded in this book represents the result of fifty years of collecting the works of British writers of the Age of Samuel Johnson.

The Age of Johnson in the Library of Loren and Frances Rothschild brings together the most comprehensive collection of rare books and autograph works in private hands of the 18th-century literary giant Samuel Johnson, together with extensive collections of the works of the other principal authors of the period long-known as the Age of Johnson— including James Boswell, Edmund Burke, Frances Burney, Oliver Goldsmith, Hester (Thrale) Piozzi, Alexander Pope, and Jonathan Swift.

An introduction to each of these authors provides information placing the author in his or her historical and literary context, and the descriptive entries for each of the over 900 individual manuscripts, letters, and rare books records bibliographical information, significant facts, and critical information about the work recorded.
The individual entries, when viewed in the aggregate, survey and illuminate the breadth and depth of the literary and intellectual canon of the authors of the Age of Johnson, illuminate their relationships and their works to one another. The text taken as a whole demonstrates why Samuel Johnson, as an individual and as an author, defined the era long named for him.
