A great variety of Collections of Voyages and Travels have been published at different periods, many of which are inaccessible from their scarcity, or from being in foreign languages: And such great numbers of Voyages and Travels to particular regions and countries have been printed, as to be Altogether unattainable by the generality of readers. Every thing, however, which could contribute to the perfection of this work has been collected, or will be carefully procured during its progress; and no pains or expense shall be withheld which, can contribute to render it as complete and comprehensive as possible. In the employment of the vast variety and extent of excellent materials, great care shall be taken to insert every useful and curious information, reduced, where necessary, to modern language; and nothing shall be omitted which is conducive to valuable information and rational amusement.
In our approach towards the present times, the multitude of particular Voyages and Travels increases prodigiously; and, in employing these, it becomes peculiarly necessary to make a selection of the best in every period, and especially of those best adapted for conveying just ideas of each geographical division and subdivision of the world; while those of less merit, but which contain useful notices of the regions and countries of which they treat, shall be carefully epitomized in illustration of the different subjects. Without the employment of discriminate selection and occasional abridgement, this work must have extended to an inconvenient and consequently expensive size, or must have been left unfinished and abrupt in some of its parts: _But abridgement shall be very seldom employed and never without acknowledgment_. Indeed, the grand object of the present work is to bring together a more complete and entire collection of Voyages and Travels, than has hitherto appeared in any language.
From the nature of the plan, it is utterly impossible to ascertain, with any precision, the exact length to which it may extend; but, so far as can be judged of at present, it is not expected to exceed eighteen or twenty volumes. Throughout the whole work, a series of Maps and Charts will be inserted in their proper places, carefully selected and constructed for the purpose of illustrating the various Voyages and Travels. At the close of the whole, a complete Index will be given to the entire series of volumes, so arranged as to form a regular _Gazetteer_ of the whole world. In every article which has been adopted into this work, the original and accessory sources of all the materials shall be distinctly indicated. Notes of explanation will be given, wherever necessary; and, as many of these are drawn from various sources, the names of the authors from whom they are adopted shall always be acknowledged: Such notes as are marked by the letter E. are by the Editor of the work.
