Lulu authors using Lulu have began to notice their online distributors vanishing away. Once upon a time Lulu books could be released with an ISBN and would gradually show up at most of the online bookstores. Now author report that they are only appearing at Amazon.com (not even Amazon.uk etc).
Staff on the forum and chat lines seem to be saying nothing had changed, but the new books are not getting the same distribution online, and old ones are being listed as out of stock by most distributors. Hopefully answers will be forthcoming, but I am not holding my breath.
Suspicions are arising that the arrangement Lulu made with Amazon had some side effects that are not favorable to their author/customers--such as not listing books with Ingram.
