There is one major thing book collectors tend to hate above others, when book covers change. There are many reasons why publishers end up making the decision to change them. A few being that the series is over and they want a new change, the cover isn't getting as much attention as they like and perhaps a movie is coming out based on the book so they decided to change it to have viewers connect both the movie and the book. But either way it frustrates readers.
I as a reader, have a love & hate relationship with cover changes. Sometimes I believe the swap is for the best, the original cover is just not just enough to catch my eye but then there are times where the cover is utterly fabulous and they swap it out to mush or what relates to mush. I understand that they change for marketing purposes, but I think Publishings should get an opinion from readers before they swap them. The decisions the publishing makes is not always the best one.
Another reason besides eye catchiness that frustrates readers, is if a series is not completed and a publishing change the covers then the reader is in a pickle. If they already owned the original set then they will never have a complete set of matching covers now because of the change, unless of course they go out and re-buy them all again. I've had this happen to me a few times already, with Perfect Ruin by Lauren DeStefano and Fire & Flood by Victoria Scott. Sometimes I think that it's a con to buy the books again, but I'm not made of money so that won't be happening for a second time.
I have collected a list of books and covers that have changed for you all, so I'll let you decide what you think about cover changes.
Note: Not all books in each series are shown, and that the cover go in order from when they were released, left to right. Right being the current cover you can purchase in stores.
