I bought the archive of Elector magazine and found many errors in that product. I emailed a detailed document to them along with all of the needed changes, Never heard a peep from anyone at elector on that. I spent probably three days solid going through and checking every single issue to fix the problems and no one from the company even took 5 minutes to write me back and acknoledge any of the work I had done.
I just wanted to make sure that the next guy that buys the very expensive USB stick of magazines would have a clean fully usable copy without duplicates or copies with the wrong pages in the index, etc. Most of the magazines (I found out later) I could have found on the internet for free download but thought it would be more handy (and quicker) just to but the archive.
In any event on the files for this project I certainly would not hold my breath waiting for them.
