Like many areas of antique collecting, antique books is a vast field. For a collector, it can be as narrow or as general as you want it to be. You could decide to collect a certain genre such as science fiction or a particular historical period. You could collect from a particular year or a certain author. You may even decide to collect books about a particular geographical area.
Once you decide what types of books you are interested in collecting, you need to become familiar with the different factors that may affect the price of a given book. The first of these factors is demand. As with other antiques and collectible items, the true value is what someone else is willing to pay for it. If a book is in great demand, other collectors will be more willing to pay a higher price to get it. The more rare a particular book is, the higher the demand for that book is likely to be. It is also important to remember that demand can change. The value of a different book may rise or fall over time as demand for the book changes.
One factor that greatly affecting demand is how many copies of a book are available. If there is a limited numbers of copies on the market, then demand, and the price of the book will likely increase. If more copies of the book are on the market, the price for a book often to falls. This is the reason limited edition and first edition copies of books are commonly more valuable than later printings of the book.
Another factor that may affect the cost of a book is the general condition of the book. Books are easily damaged if they are not handled with caution. This becomes more important as a book ages. Pages get more brittle over time and the threads in the binding weaken. Older books require more care when they are handled.
When thinking about an investment in an antique book, make certain to consult a reputable dealer. Someone who is experienced and knows the business is a great deal more apt to be able to attest to the authenticity of the book in question. It is also less likely that they will carry repaired or damaged books in their collections.
When you have determined the book that you'd be interested in purchasing you should comparison shop to make sure you are getting a fair price. The cost of a book is apt to be different depending on the dealer, and that price difference could be significant, so a bit of homework could save you a substantial sum of money.
Once you've found the antique book you want, be certain to take the time to carefully examine the book's condition. Look for damaged or missing pages, broken or damaged binding, and stains on the book's cover. Also check the title page to be certain the book was properly labeled, and if it's being sold as a first edition that it really is a first edition.
Finding the book you want in the desired condition can take time. Be patient. Don't rush into a purchase just because a book is available. Take the time to make sure it is a book worth investing in.
