So here is your list, reader, take your choice. But perchance you are already numbered among the elect, one of those magi among bibliophiles who are at once the despair of the booksellers and the wise men of their generation? Is it not to the specialists that we owe the bulk of our knowledge of old books—for who else is it that produce the bibliographies, numerous but not nearly numerous enough, that delight the heart of the collector? All praise to them, and, brother bibliophile, if you are not yet of their number in heart at least, read through the foregoing list once more and put a mark with your pencil against the heading which is most to your taste. If you do not see your chosen subject at once, a scrutiny will probably discover it for you included in another and wider subject.[74] For example, Astronomy and Astrology, inseparably bound up in the ancient works, are included in the heading 'Occult.' Herbals, which deal with the medicinal qualities of plants, you will find under 'Medical.'

Is your purse a long one? Would you not like to garner folios and quartos with weird and heavy types that speak of a craft yet in its infancy; books that perchance have seen or even been handled by the actual combatants of Barnet or of Bosworth Field; books with monstrous crude yet wholly delightful woodcuts that bring before us the actual appearance of our forebears under the King-maker, Richard Crouchback, and Harry Richmond? Or would you like to gather to yourself as many examples as you may, in the finest possible condition, of the exquisite art of Aldo Manuccio the elder? But perhaps the following, from a recent catalogue, represents a class (20) more to your palate.

L'Histoire du tres fameux et tres redoute Palmerin d'Olive . . . . traduite de Castillan en Francoys reueue et derechef mise en son entier, selon nostre vulgaire moderne et usite, par Jean Maugin, dit l'Angeuin. With 45 large spirited woodcuts (some being nearly full-page) representing duels, battles, etc., and 132 large ornamental initial letters. Folio, Paris, 1553.

Is your purse a light one? Then fifteenth-century books are denied you, as are all other esteemed works of the Middle Ages such as romances and classics. But there is hardly another heading in our list, save perhaps the first editions of the great authors, which you may not make your own. Almost every subject has its bibliography, and many fresh volumes are added yearly to the ever-increasing list of 'books about books.' You will find what bibliographies have appeared upon your particular subject, up to 1912, by referring to Mr. W. P. Courtney's 'Register of National Bibliography,' which should be (if indeed it is not) in every public library throughout the kingdom.

Some day an enterprising public body will purchase a building with fifty-five rooms (or thereabouts), each of which will contain a small and carefully selected collection of books on each one of these subjects. Each room will have its own catalogue and its own librarian, who will be an expert in the subject over which he presides. The rooms, of course, will vary in size according to the magnitude of the subject and the number of sub-headings which it comprises. Readers will have access to the shelves in almost every case, books of great value alone being kept under lock and key.

How invaluable such a library would be, and what a vast amount of time would all readers be saved! We should know instantly to whom to turn for expert advice upon any subject—for the sub-librarians would naturally be acquainted with more than the mere outsides of the volumes in their charge. We should be able to handle the latest works upon our subject immediately; and we should have, ready to our hand, a history of its literature from the earliest times to the present day.

As to whether the acquisition of knowledge by this method would not turn us all into journalists, however, is another matter.

With the first heading in our list shall be included several others, namely (2) Africa; (5) Australasia; (55) Travels and Explorations (which heading includes every land under the sun not specially mentioned in our list), and (56) Voyages and Shipwrecks; in short, all those subjects which concern 'foreign parts.' They are subjects which are most likely to engage the attentions of collectors who have been seafaring in their time, though, as has been shown in [Chapter II.], it is not every traveller who has been far afield.

Books on Arctic and Antarctic exploration, as well as whaling voyages, comprise much reading that is as interesting to the landsman as to the sailor. Most of its literature is within easy reach of the collector of modest means, though the earlier volumes are naturally increasing gradually in price. One of the hardest to obtain is William Scoresby's 'Account of the Arctic Regions,' which was published in two octavo volumes at Edinburgh in 1820. You will be lucky if you find a clean sound copy of it with the plates unspotted. It is now getting very scarce, as is Weddell's 'Voyage towards the South Pole in 1822-24' (octavo, London, 1825).

Each of these headings can be subdivided according to your requirements. Africa you may divide conveniently into West, South, East, and Central; North Africa being best classified under the various countries which it contains, namely, Algiers, Morocco, Tripoli, and Tunis. Egypt, of course, has a vast literature of its own. Similarly books on Australasia may be divided into those which deal with Polynesia, New Guinea, Australia (again divided into its states), Tasmania, and New Zealand; though, properly speaking, the first of these should be classified under the heading 'Voyages.'
