Wordcatcher Author Hub is a resource to increase your knowledge and skills. This section will grow, and it's led by the questions you ask. Chances are someone else is wondering the same as you so don't be afraid to ask questions. Just email firstname.lastname@example.org, and we'll either point you in the right direction, or set up a new page to answer your query.

Even in a small bookshop you can develop a relationship that can garner surprising results. We don't have the resources to contact every bookshop, so you need to know the best approach.
