As I stated previously, we have submitted our book to Barnes and Noble, but have not heard back yet.
It sounds as though you submitted your title(s) to B&N Small Press division, which is a clearing house for small presses and/or PODs who don't have a distributor and want get their books listed in B&N's database - or hopefully, get a PO for an order.
Going through the Small Press division is the only way these publishers can get into the B&N database. Without that, individual stores won't order the books should there be demand. In cases where a publisher provides a big promotion/marketing plan, the Small Press division may choose to actually order a small number of units to disperse to various stores.
If memory serves, the process was often laborious since books and paperwork were often lost, or someone keypunched in a wrong ISBN, so your book(s) wouldn't show up in their databases. The small press division is a lot of white noise which can age a publisher faster than heavy drinking.
We are a traditional publisher. We use Lightning Source as our printer which does both POD and offset. Unfortunately all books are list as POD from them. However we do sell to distibutors and we do accept returns.
Nearly every good printer nowadays does both offset and digital. Most PODs and small presses use LSI to get their titles listed with Ingram and the online databases. LSI charges more for those services.
I know of a few publishers who use LSI to handle their backlist, and those aren't listed as POD. POD companies' books, OTOH, are listed as POD with the bookstore databases unless the publisher dispels LSI of the notion that they're POD.
Would you mind expanding on what you mean by "We are a traditional publisher"? I ask because all too often we hear new publishers say this, and their interpretation of "traditional" may differ greatly from the going consensus.
For example, a mainstream publisher has distributors who do the footwork of selling your catalog to the national accounts and to the warehouse distributors. Or they have their own sales teams who accomplish the same thing - which means that you're pubbing at least five titles per season in order to get an appointment with genre buyers. It doesn't sound like you've gotten to that point yet, so the big question I'm sure that's running through author's minds is how are those books getting to market?
I have contacts with PMG Intl, B&T, and Barnes and Noble, I am working them, the ones I know, first and then we will start looking at others.
It is very, very, very hard to get their attention because you are one of hundreds of small presses who are vying for shelf space. The problem is that you're competing against many other publishers who have sales teams selling directly to the genre buyers. These publishers have large print runs sitting in the warehouse, ready to shoot out the door.
In general, small presses lacking distribution or sales teams usually establish contacts with individual bookstores and get their stock placed there. It's not perfect, but it's a start up a very big hill.
