Hollis's main contribution to public service was protecting and advancing English liberty by circulating appropriate books on government. From 1754, he reprinted and distributed literature from the seventeenth-century, including works such as
Toland's
Life of Milton, tracts by
Marchamont Nedham,
Henry Neville, and
Philip Sidney, and
John Locke's
Two Treatises of Government. From 1760, he had commissioned the bookseller
Andrew Millar to publish works advocating republican government, including
John Milton (1760), John Toland (1760),
Algernon Sidney (1763), Henry Neville (1763) and John Locke (1764). The books were elegantly bound to give them greater effect and tooled with libertarian ornaments such as the liberty cap and owl. He also published writings by American colonists on the Stamp Act crisis, including
John Adams's
Dissertation on the Canon and the Feudal Law (1765). To start with the tracts were directed towards libraries throughout Britain and continental Europe; later he turned his generosity to America. He continued his great-uncle Thomas's practice, as a great benefactor to American colleges, especially
Harvard, sending donations and numerous books, often decorated with libertarian symbols. From 1755, his principal American correspondent was
Jonathan Mayhew of
Boston, and, after Mayhew's death in 1766,
Andrew Eliot. His other benefactions included substantial donations to
Bern Library and to the
University of Leiden Library. Hollis was the patron and a friend of
William Harris (historian). He died suddenly on 1 January 1774 aged 53. He was unmarried, and after minor legacies left his estates to
Thomas Brand, who added Hollis's name to his own. ==References==
