History
Since the invention of the printing press in the 15th century, the adornment of signed bookplates to the inside of books has been regarded as a legitimate and distinguished art form. Many famous figures in history have designed their own personal signed bookplates. Queen Victoria, Franklin Roosevelt and Walt Disney are just a few examples.
Types
Since the bookplate's inception, many techniques have been used in their creation. These include woodcuts, metal engravings, silk-screens and drawings done with pen or pencil. Bookplates can also be classified as an ownership, or owner-signed, bookplate or an authorship, or author-signed, bookplate.
Worth
Bookplate collecting is a worldwide phenomenon with societies established all over the globe. Both duplicates and originals are traded and alter the value of the book. Unless signed by a notable figure, an ownership bookplate will decrease the value of a book. An authorship bookplate will increase the value of a book.
