The regard which was always paid, by the collectors of this library, to that remarkable period of time, in which the art of printing was invented, determined them to accumulate the ancient impressions of the fathers of the church; to which the later editions are added, lest antiquity should have seemed more worthy of esteem than accuracy.

History has been considered with the regard due to that study by which the manners are most easily formed, and from which the most efficacious instruction is received; nor will the most extensive curiosity fail of gratification in this library, from which no writers have been excluded, that relate either the religious, or civil affairs of any nation.

Not only those authors of ecclesiastical history have been procured, that treat of the state of religion in general, or deliver accounts of sects or nations, but those, likewise, who have confined themselves to particular orders of men in every church; who have related the original, and the rules of every society, or recounted the lives of its founder and its members; those who have deduced in every country the succession of bishops, and those who have employed their abilities in celebrating the piety of particular saints, or martyrs, or monks, or nuns.

The civil history of all nations has been amassed together; nor is it easy to determine which has been thought most worthy of curiosity.

Of France, not only the general histories and ancient chronicles, the accounts of celebrated reigns, and narratives of remarkable events, but even the memorials of single families, the lives of private men, the antiquities of particular cities, churches, and monasteries, the topography of provinces, and the accounts of laws, customs, and prescriptions, are here to be found.

The several states of Italy have, in this treasury, their particular historians, whose accounts are, perhaps, generally more exact, by being less extensive; and more interesting, by being more particular.

Nor has less regard been paid to the different nations of the Germanick empire, of which neither the Bohemians, nor Hungarians, nor Austrians, nor Bavarians, have been neglected; nor have their antiquities, however generally disregarded, been less studiously searched, than their present state.

The northern nations have supplied this collection, not only with history, but poetry, with Gothick antiquities and Runick inscriptions; which, at least, have this claim to veneration, above the remains of the Roman magnificence, that they are the works of those heroes by whom the Roman empire was destroyed; and which may plead, at least in this nation, that they ought not to be neglected by those that owe to the men whose memories they preserve, their constitution, their properties, and their liberties.

The curiosity of these collectors extended equally to all parts of the world; nor did they forget to add to the northern the southern writers, or to adorn their collection with chronicles of Spain, and the conquest of Mexico.
