So your ready to sell your used books, you have called a book dealer to come over and take a look. I am going to give you some advice on what to expect and what not to expect.
1. On average I only buy one out of every 5 house visits. There are numerous factors on why but briefly some are as follows. Condition, subject matter and the factor of how fast I can turn around and move them myself. If a book dealer does not buy your books, do not be offended, this is a business and the lack of an offer is strictly a business decision.
2. I need time to look over your books. If your in rush for time, schedule the appointment when you have a few hours available. I want to offer you the best price I can, and when looking at 1000 books and telling me I have 5 minutes does not work.
3. Please do not tell me that you saw a similar looking book like yours on antique road show or some other PBS series and the proceed to tell me it has to be worth tens of thousands of dollars. Similar and the same are two different things. I have been to house calls and other dealers have told me the same story where a person is determined there book is that rare, out of print masterpiece and will be featured on the local news. This never happens.
4. Don't be afraid to ask questions. If I make an offer on some books and not others, it's ok to ask why. If I say I won't be able to make an offer, by all means ask why and gain some knowledge. Again it's not a personal decision against you or your collection, but a business matter.
5. As a book buyer I am bound by a professional and ethical code to provide the best price possible. In rare instances I may need to make phone calls and seek other professional's advice before I make an offer. Please understand this is to your benefit. Again I want to offer the best price for your books.
