Query: Poor quality reproduction of favorite

Anne Perry has been one of my favorite authors for many, many years. I was delighted to see that the Charlotte and Thomas Pitt series is available on Kindle. However, as I am re-reading the old favorites, I am very disappointed by the poor reproduction quality of the entire series. Many words are misspelled through obvious optical character recognition errors. The price of each book warrants at least a proofread of the content. My rating is based on this issue; a review of the writing and storyline would be much, much higher.
