Not less important than the preservation of newspapers is that of reviews and magazines. In fact, the latter are almost universally recognized as far more important than the more fugitive literature of the daily and weekly press. Though inferior to the journals as historical and statistical materials, reviews and magazines supply the largest fund of discussion concerning such topics of scientific, social, literary, and religious interest as occupy the public mind during the time in which they appear. More and more the best thought of the times gets reflected in the pages of this portion of the periodical press. No investigator in any department can afford to overlook the rich stores contributed to thought in reviews and magazines. These articles are commonly more condensed and full of matter than the average books of the period. While every library, therefore, should possess for the current use and ultimate reference of its readers a selection of the best, as large as its means will permit, a great and comprehensive library, in order to be representative of the national literature, should possess them all. * * * * * The salient fact that the periodical press absorbs, year by year, more of the talent which might otherwise be expended upon literature of more permanent form is abundantly obvious. This tendency has both its good and its evil results. On the one hand, the best writing ability is often drawn out by magazines and journals, which are keen competitors for attractive matter, and for known reputations, and sometimes they secure both in combination. On the other hand, it is a notable fact that writers capable of excellent work often do great injustice to their reputations by producing too hastily articles written to order, instead of the well-considered, ripe fruits of their literary skill. Whether the brief article answering the limits of a magazine or a review is apt to be more or less superficial than a book treating the same topic, is a question admitting of different views. If the writer is capable of skilful condensation, without loss of grace of composition, or of graphic power, then the article, measured by its influence upon the public mind, must be preferred to the more diffuse treatise of the book. It has the immense advantage of demanding far less of the reader's time; and whenever its conclusions are stated in a masterly way, its impression should be quite as lasting as that of any book treating a similar theme. Such is doubtless the effect of the abler articles written for periodicals, which are more condensed and full of matter in speedily available form, than the average book of the period. In this sense it is a misuse of terms to call the review article ephemeral, or to treat the periodicals containing them as perishable literary commodities, which serve their term with the month or year that produced them. On the contrary, the experience of
