We here terminate our rapid survey of the principal libraries of Europe. Small, however, would be the interest which one should feel for these magnificent establishments were they designed solely for the benefit of a few individuals, or of any favored class. They would still be splendid monuments of the productive powers of the human mind, and of the taste or learning of their founders; but they would have no claims to that unbounded admiration with which we now regard them. There is a republican liberality in the management of the great libraries of the continent of Europe which is well worthy of our imitation. In these alone is the great invention of printing carried out to its full extent, by the free communication of all its productions to every class of society. No introduction, no recommendation, no securities are required; but the stranger and the native are admitted, upon equal terms, to the full enjoyment of all the advantages which the uncontrolled use of books can afford. As this mode of accommodating, or rather of meeting the wants of the public, is the real object of these institutions, they are provided with librarians, who, under different titles corresponding to the duties imposed upon them, receive from government regular salaries proportioned to their rank and to the services which they perform. To these the immediate superintendence of the library is wholly intrusted, and at a stated hour of every day in the week, except of such as are set apart for public or religious festivals, they open the library to the public. There, undisturbed, and supplied with every thing the collection contains that can aid him in his studies, the scholar may pass several hours of every day without any expense, and with no other care than that natural attention to the books he uses, which every one capable of appreciating the full value of such privileges will readily give. Nor do his facilities cease here. The time during which the libraries remain open may be insufficient for profound and extensive researches, and the writer who has to trace his facts through a great variety of works, and to examine the unpublished documents to be found in public libraries alone, would be obliged to sacrifice a large portion of every day if his studies were regulated by the usual hours of these institutions. For such persons, a proper recommendation can hardly fail to procure the use, at their own houses, of the works they may need. In this manner the door is thrown open to every one who wishes to enter, and science placed within reach of all who court her favors.
