This is probably so over the top but please bear with me

. I feel so strongly about this that my fingers are positively burning at the keyboard...and if I may begin by telling my own story you might understand why I feel this way about self published books!
Several years ago, I went through masses of research to write a biography of one of Queen Victoria's granddaughters. At that time, there was no other biography of her available in the UK. It was a labour of love and - since I can neither cook nor sew nor do anything that is practically useful, but know I can write - I put my whole self into it. It was shortlisted for the UK Biographers' Award (for as yet unpublished works) in 2003 and received a wonderful response from many established biographers when I attended the ceremony. Within a couple of months I was offered a contract for the biography by a very reputable publishing house. Unfortunately, the editor was going on sabbatical to Australia for 6 months so asked me to be patient until her return. I was patient. I had the contract and continued to research further projects....A few days before the 6 months was over, I received a letter from the marketing department to say markets had changed and they would not honour the contract. I received half of the original agreed royalty payments and that was that...
Hugely disappointed, as you can imagine, I nonetheless believed in my book (and other books I had written) and began from scratch again. The responses I received from some publishers junior readers were beyond belief: "We like your style, and the story is wonderful
but there is insufficient scandal to reach a modern reader..." Or worse, "Wonderful!! I really loved this but my bosses tell me people want real life - drugs, abused children - and there is nothing I can do with your book" ????
Then my book was accepted by a publisher in America. It was butchered and filled with errors - I had no chance to proof read it - and, though it sold, I did not receive one penny for what I had written. I withdrew the contract after a year. And an agent asked for it...kept it for 6 months, asked me not to approach other agents and then forgot about it...Yeah right!
Who are these people who own the publishing world? In England now there are about 5 publishers who own everything. A close associate write hugely successful academic Maths books. Anything he writes - and he writes brilliantly - is taken up by publishers but they have told him that he arrived at the perfect time and they take on no one new anyone.
You ask about self publishing? I say it is mightily empowering!!! When you have a story to tell - when that story means to much to you that you are free from someone else's (some marketing department's) idea of what is popular, what will sell and what won't...when you can write honestly and not think of a quick sale or a cheque, but rather of beauty and beautiful words and literature and apply yourself to bringing out something that will uplift and inspire as well as entertain your readers...when you can deeply empathise with the people about whom you are writing and just tell their story...No wonder all these people self published:

Oh...come on...what's the big deal? Some junior editor fresh from college wanting to make a career decides whether or not your book is worth promoting and decides what will sell? Or you write something really wonderful and do it yourself....
Well...the perfect answer for me was to set up a new independent publishing house as Judy Piatkus did - founded in her bedroom I believe - and turned into a massive publishing company. Do we need other people to tell us what is worth reading or can we decide for ourselves....
