That a volume so comprehensive in its scope and so multitudinous in its details should be wholly without errors and omissions is impossible; and we trust that any of our readers who detect such will discharge a part of the obligation they are under to Mr. Allibone by communicating them to him for the benefit of a second edition.

Next to knowledge itself, perhaps the best thing is to know where to find it.  To make an index that shall combine completeness, succinctness, and clearness,—­how much intelligence this demands is proved by the number of failures.  Mr. Truebner’s volume contains, 1st, some valuable bibliographical prolegomena by the editor himself; 2d, an historical sketch of American literature, which is not very well done by Mr. Moran, and would have been admirably done by Mr. Duyckinck; 3d, a full and very interesting account of American libraries by Mr. Edwards; and 4th, a classed list of books written and published in the United States during the last forty years, arranged in thirty-one appropriate departments, with a supplementary thirty-second of Addenda.  In some instances,—­as in giving tables of the proceedings of learned societies,—­the period embraced is nearly a century.  A general alphabetical index completes the volume.  The several heads are, Bibliography, Collections, Theology, Jurisprudence, Medicine and Surgery, Natural History (in five subdivisions), Chemistry and Pharmacy, Natural Philosophy, Mathematics and Astronomy, Philosophy, Education (in three subdivisions), Modern Languages, Philology, American Antiquities, Indians and Languages, History (in three subdivisions), Geography, Useful Arts, Military Science, Naval Science, Rural and Domestic Economy, Politics, Commerce, Belles Lettres, Fine Arts, Music, Freemasonry, Mormonism, Spiritualism, Guide Books, Maps and Atlases, Periodicals.  This list is enough to show the great value of the “Guide” to students and collectors.  The volume will serve to give both Americans and Europeans a juster notion of the range and tendency, as well as amount, of literary activity in the United States.  As the work of a cultivated and intelligent foreigner, it has all the more claim to our acknowledgment, and also to our indulgence where we discover omissions or inaccuracies.

The second volume whose title stands at the head of our article would demand no special notice from us, were it not for the admirable manner in which it is executed and the judgment evinced in the selection of the books which it catalogues.  The Boston Library may well be congratulated on having at its head a gentleman so experienced and competent as Professor Jewett.  He has hitherto distinguished himself in a department of literature in which little notoriety
