First, let me say that I'm not a nit-picker, but... I'm currently reading a commercial novel with so many inaccuracies that it's affecting my suspension of disbelief. This novel is not self-published; it's in hardback from a big six imprint. (I'm NOT talking about SPAG but rather technical and anachronistic issues. Such as: 'The year was 1958. Free Bird blared from the radio speakers." I expect these issues from a self-pub book (no offense to anyone) but not from a book released by a big six publisher. So, this got me wondering about the person at the publisher who first received the submission, and the others they passed it to, and then the editor they assigned to it. (assuming they still do this? I dunno) I got to thinking about all the eyes who read this book but didn't catch the fairly glaring things I'm noticing. So, I ask the question: have you ever known the publisher/editor to challenge inaccuracies in books prior to publishing? Because 1--this one must have slipped through somehow, or 2--my assumption is wrong to begin with, and pubs do NOT inspect or fact check authors' submissions. PS ...not referring to beta's here. That's on the author's end, and prior to submission.
