Hyak nin is’shiu, or Stanzas by a century of poets, being Japanese Lyrical Odes, by Frederick V. Dickins, M.B. , 1866
With an extensive preface detailing the painstaking effort of the author to accurately translate these poems, “familiar in every Japanese household,” this book includes poems, explanatory notes, text in Roman and Japanese characters, a full index and a catalog of Japanese author titles. It was scanned as part of the Google Books Project.
Librarians’ notes indicate that the book was given to the Harvard Library by George W. Wales of Boston in 1875 and that its paper was deacidified in 1992.
Acidified paper is the reason so many books and papers created after 1840 are yellowed and crumbling. Michigan State University library offers this description of deacidification of acidic paper.
