It seems unlikely that the person in question has read all the books - why would you read so many books by authors you're clearly not enjoying, or go to the trouble of tracking down some fairly obscure titles to do so? Which makes me wonder why anyone would go to the trouble to be so negative, none of the answers I come up with are particularly encouraging.
I've followed Scott's blog for a while now, and enjoy his enthusiasm as well as his general taste in books, I've followed Dean street Press for even longer - they seem like nice people - so I want to add my voice in praise for what they're doing.
Any publisher who wants to devote themselves to rescuing long forgotten titles, especially when they're helping restore the easily lost voices of generations of women, get my thanks and praise. If it's not your cup of tea it's easy to ignore these books - they're not piled high in every bookshop, it seems unlikely that they're having any noticeable impact on sales for hard up contemporary authors, but for those of us who are interested it's great to have easy access to these books.
I bought a couple of titles (e versions, they're on my phone, it will take me forever to get round to reading them because I rarely do e books, but it was the end of an expensive month and the cheap option) but they look good, and like Simon I want to balance the negativity of those reviews with a moment of positivity.
Not that I have an issue with negative reviews, certainly not when they're specific as to the issues the writer has with the book (and I'm confident that the reviewer actually read the book) but in this case they aren't in any way helpful - and have hopefully, thanks to Simon, had the opposite effect to the one intended.
