The catalogue is a detailed study of Oxford manuscripts of the Wycliffite Bible, the first complete translation of the Bible in English.

The director of the famed Bodleian Libraries at Oxford narrates the global history of the willful destruction—and surprising survival—of recorded knowledge over the past three millennia. Libraries and archives have been attacked since ancient times but have been especially threatened in the modern era. Today the knowledge they safeguard faces purposeful destruction and willful neglect; deprived of funding, libraries are fighting for their very existence. Burning the Books recounts the history that brought us to this point. Richard Ovenden describes the deliberate destruction of knowledge held in libraries and archives from ancient Alexandria to contemporary Sarajevo, from smashed Assyrian tablets in Iraq to the destroyed immigration documents of the UK Windrush generation. He examines both the motivations for these acts—political, religious, and cultural—and the broader themes that shape this history. He also looks at attempts to prevent and mitigate attacks on knowledge, exploring the efforts of librarians and archivists to preserve information, often risking their own lives in the process. More than simply repositories for knowledge, libraries and archives inspire and inform citizens. In preserving notions of statehood recorded in such historical documents as the Declaration of Independence, libraries support the state itself. By preserving records of citizenship and records of the rights of citizens as enshrined in legal documents such as the Magna Carta and the decisions of the US Supreme Court, they support the rule of law. In Burning the Books, Ovenden takes a polemical stance on the social and political importance of the conservation and protection of knowledge, challenging governments in particular, but also society as a whole, to improve public policy and funding for these essential institutions.

The "Iter Italicum" serves as a useful reference work for scholars in the history of philosophy, the sciences, classical learning, grammar and rhetoric, Neolatin literature, historiography of the theory of the arts and of music and related subjects. By scanning the volume or through this index, scholars will be able to find source material for individual writers as well as for certain subjects, problems or themes. By indicating for each manuscript its location and shelf-mark, scholars will find it easier to order microfilms or to pursue more detailed studies of some of the manuscripts listed. The volumes should also prove useful for librarians as a reference for the holdings of their own or other libraries.
