"First, the number of books; secondly, their quality; and, lastly, the order in which they ought to be ranged.

"As to the quantity, regard must be had, as well to places as to persons; for should a man of moderate fortune propose to have a Library for his own use only, it would be imprudent in him to embarrass his affairs in order to effect it. Under such circumstances he must rather consider the usefulness than the number of books, for which we have the authority of Seneca, who tells us that a multitude of books is more burthensome than instructive to the understanding.

"But if a private person has riches enough for founding a Library, as well for his own use as for the public, he ought to furnish it with the most useful volumes in all arts and sciences, and procure such as are scarcest and most valuable, from all parts, that the learned, of whom there are many classes, may instruct themselves in what may be useful to them, and may gratify their enquiries. But as the condition and abilities of such as would form Libraries are to be distinguished, so regard must likewise be had to places, for it is very difficult to procure, or collect books in some countries, without incredible expense; a design of that kind would be impracticable in America, Africa, and some parts of Asia; so that nothing can be determined as to the number of books, that depending entirely upon a variety of circumstances, and the means of procuring them, as has been observ'd before.

"As to the second topic, special care must be taken in the choice of books, for upon that alone depends the value of a Library. We must not form a judgment of books either by their bulk or numbers, but by their intrinsic merit and usefulness. Alexander Severus's Library consisted of no more than four volumes, that is the works of Plato, Cicero, Virgil, and Horace. Melanchthon seems to have imitated that Prince, for his collection amounted to four books only, Plato, Pliny, Plutarch, and Ptolemy.

"There is another necessary lesson for those who form designs of making libraries, that is, that they must disengage themselves from all prejudices with regard either to ancient or modern books, for such a wrong step often precipitates the judgment, without scrutiny or examination, as if truth and knowledge were confined to any particular times or places. The ancients and moderns should be placed in collections, indifferently, provided they have those characters we hinted before.

"Let us now proceed to the third head, the manner of placing books in such order, as that they may be resorted to upon any emergency, without difficulty, otherwise they can produce but little advantage either to the owners or others.

"The natural method of placing books and manuscripts is to range them in separate classes or apartments, according to the science, art, or subject, of which they treat.

"Here it will be necessary to observe, that as several authors have treated of various subjects, it may be difficult to place them under any particular class; Plutarch, for instance, who was an historian, a political writer, and a philosopher. The most advisable method then is to range them under the head of Miscellaneous Authors, with proper references to each subject, but this will be more intelligible by an example.

"Suppose, then, we would know the names of the celebrated Historians of the ancients; nothing more is necessary than to inspect the class under which the historians are placed, and so of other Faculties. By this management, one set of miscellaneous authors will be sufficient, and may be resorted to with as much ease and expedition as those who have confined themselves to one subject. In choice of books regard must be had to the edition, character, paper and binding. As to the price, it is difficult to give any positive directions; that of ordinary works is easily known, but as to such as are very scarce and curious, we can only observe that their price is as uncertain as that of medals and other monuments of antiquity, and often depends more on the caprice of the buyer than the intrinsic merit of the work, some piquing themselves upon the possession of things from no other consideration than their exorbitant price."

Dr. Byrom's quaint library is still preserved at Manchester in its entirety. Bishop Moore's fine collection finds a resting place in the University Library at Cambridge, and the relics of the Library of Harley, Earl of Oxford, a mine of manuscript treasure, still remain one of the chief glories of the British Museum. How much cause for regret is there that the library itself, which Osborne bought and Johnson described, did not also find a settled home, instead of being dispersed over the land.
