The term ‘rare’ is vague, and one might assume that a book is rare due to its old age or due to the fact that it is limited in quantity. However, a rare book can be both. Not all rare books are old, but all rare books are unequivocally valuable. Therefore, it is necessary to distinguish between ‘antiquarian’ books and ‘rare’ books; ‘antiquarian’ is defined to be both old in age and rare, while ‘rare’ encompasses both old and new.
Antiquarian bookseller Jeremy M. Norman provides a useful criterion in identifying rare books with six key points:
- The scarcity of the books: books with 25,000 copies or more are not considered rare
- Significance of the book’s contents: a book could be the first account of a historical exploration to Egypt or could contain some private information about a historical figure
- The physical aesthetic of the book: a book could be printed on exotic paper with rare watermarks, or could contain intricate illustration, which could be highly valuable to collectors
- A book’s ‘imprint’ according to Norman: books printed in a certain time and place are well known to be rare
- Significant associations: books or texts associated to different important figures, either containing their signatures or initials add a substantial amount of value to rare books
- The condition of the book: rare books are not as available as most common books, and are not always subject to the damages and repairs to that of a common book.
