I agree with dgcasey. I hate Goodreads as an author - it's near enough impossible to get your covers to change once they appear there. For some reason one book in my mystery series is there without a cover image and I can't work out how to get one added. There are books there that I unpublished ages ago and can't get rid of.
You can't get rid of books EVER on Goodreads. Doesn't matter if it was a freebie you only gave away to your mailing list, or a Kindle-only book, or you unpublished it donkey's years ago, if it was ever 'published' anywhere at any time, it stays. And they get to say what 'published' means. I've seen stuff on GR that was only ever 'published' on Wattpad, for instance.
Some stuff you can change yourself if it's your own book and you're registered there as an author. Some things need a librarian and some things can only be done with a super-librarian. And some things you can ONLY do yourself, and not even a librarian can do it. It's barking mad.
When I first joined GR years ago, I belonged to several really active groups and found tons of great books to read that way. The discussions were terrific. But somehow it all went to hell in a handcart, and now I can't find any half-way decent groups at all.
GR would be far more appealing to authors with a few simple changes. Keeping the author profile separate from the personal one, for one thing. Having a sensible author dashboard for all your pen names, and allowing an author to see all new reviews on all books. Sensible advertising. A simpler way to change the default cover, or add a new edition (you really shouldn't have to create a whole new edition from scratch when you just add a paperback or audiobook to an existing Kindle book).
And as a reader, for the love of all that's holy, yes, a DNF shelf [**] and can we PLEASE sort an author's books by publication date? They're great with series, but sometimes I just want to see an author's whole career in date order. Plus, I'd like to customise the front page and get rid of all the stuff that I'm never, ever going to be interested in.
[**] DNF books won't get added to your Challenge for the year if you leave the date read blank, but a DNF shelf would be more elegant.
