3 Helpful Hints I Use to Evaluate Online Booksellers
1. Contact the bookseller before making a purchase- One of the best methods I have used to determine the responsiveness and reliability of a particular online bookseller is to email them a brief clarification question, such as "When was this particular edition published and by whom?" (assuming this is not listed in the description) or "Is this particular book currently in stock?" This is an important question to ask, because not only can you verify that the book you desire is actually available, but you can also judge the customer service skills of the bookseller by their response time and friendliness.
For more expensive purchases, I usually ask a bookseller to email me a digital photograph of the dustjacket and copyright page. There is nothing to replace the touch and feel of a book in person, but a couple of digital photographs can give you a better idea of a book's overall condition. I have found that booksellers who respond within one or two business days (over the weekend) tend to be more reliable and professional. The sellers who do not respond to your emails or seem rude/stand-offish are not worth dealing with.
2. Feedback Rating- Perhaps the most obvious method to determine whether or not you are dealing with a professional seller. While the feedback system was first introduced by Ebay, it is now used by Amazon, Alibris, and many other bookselling websites. While it can help identify the most obvious scam artists, it is not always so easy to separate the professional sellers from the hobbyists and college students who use their books as food trays and beer coasters.
While a 90% rating may seem like a grade A seller, in reality, a rating of 90% is more like a C- in my opinion. Books from these sellers typically arrive in poor packaging, a week or two later than expected (allow 5-14 days for Media/Standard Mail shipments to arrive and 2-5 days for Expedited), and usually not in the condition described. I have had instances where a seller with a 90% rating described a book as Very Good and it was, in fact, brand new, but more frequently a book described as Very Good contains a plethora of highlighted pages and a heavily creased front cover.
I typically will only buy from sellers with an Ebay feedback score of 97% or higher or an Amazon feedback rating of 95% or 5 stars. If a seller does not meet this requirement, I will evaluate his feedback score within the last several months to look for red flags like:
1 out of 5: The book took two months to arrive. No response to emails.
3 out of 5: The book was no longer available and the order was cancelled (happens occasionally, even to the most reliable booksellers).
1 out of 5: Received the book, but not in the condition described, and much later than expected.
3. Book Descriptions- Here is where you can separate the bookselling veterans from the newcomers. While newcomers typically describe books using phrases like "pretty good, read once and didn't like it", the old school, highly professional bookseller's description will look more like this-
12vo. London, George Bishop. 1600. 3 vols. Small folio (292 x 191 mm.). Modern brown morocco, spine in six compartments with raised bands, lettered in gold, decorative blind-stamped borders on sides, g.e. Woodcut initials, and folding facsimile map. (24), 619, (1 blank); (16), 312, 204; (16), 868 pp.
For books published within the last 50 years or so, I prefer a description somewhere in the middle. I would like the general public to be able to understand the description, but I would also like a seasoned book collector to be able to imagine the book in his hands from my description. I always include the publication date and publisher, as well as the condition of the dustjacket and any noticeable flaws (creasing, bumping, underlining/highlighting, chipping, etc.) Perhaps descriptions are a matter of personal preference, but a general rule of thumb would be- "The longer and more detailed the description, the longer the bookseller has been in business."
Two other important indications which separate the professional bookseller from the crowd include a clearly stated Customer Satisfaction Guarantee and/or a membership in an association such as the ABA (Antiquarian Booksellers Association) or IOBA (Independent Online Booksellers Association, of which I am a proud member).
