I just finished correcting the layout version of my book. to my dismay there were a number of correction that I thought should have been caught during my editing process with you. I an sending you the marked PDF file for your review. Because there are more that 50 revisions I will have to pay extra for the correction. Since I am new to this process, help me understand the editing process. I thought the process was to catch many of the errors ai missed from being so close to the project. the number of wrong words found in the final edit should not have been so high. Please advise.
