Note: My focus here is on the major publishing houses because I had a greater sample size to work with. For a lot of the smaller independent publishing houses, I had only read a few books from each of them and so I was unable to perform thorough analyses. If you're interested though, out of the smaller publishing houses, Candlewick Press came out on top with a solid 5 out of 5 average rating - all down to my love of Patrick Ness.
Penguin is part of Penguin Random House now, but most of my ratings on this blog are from the time when Penguin and Random House were separate entities so I will be treating them as separate here as well. When separated from Random House, Penguin has my overall highest rating! I was a little surprised by this, but pleasantly so. When looking at my highest rated books from Penguin over the years, most of them are contemporary, which is even more surprising considering I wouldn't consider that my favourite genre at all. Then again, Stephanie Perkins, John Green, and Gayle Forman are all based out of Penguin and I've loved all of their books so far, so maybe it's not so surprising after all.
Overall Average Rating: 4.09
Hachette Book Group was my second overall highest rated publisher. This makes sense to me as I know that some of my most favourite books have come from them over the years. Namely, the Daughter of Smoke and Bone Trilogy by Laini Taylor and Queen Jo's three adult books The Casual Vacancy, The Cuckoo's Calling, and The Silkworm.
Overall Average Rating: 4.05
Macmillan has a pretty high overall rating and of course it would, being the home of The Lunar Chronicles by Marissa Meyer and The Grisha by Leigh Bardugo - definite faves!!
Overall Average Rating: 3.83
When separated from Penguin, Random House has a relatively low overall rating. Then again, Random House has also published two of my most heartbreakingly favourite books of all time: The Road by Cormac McCarthy and The Book Thief by Markus Zusak, so they're still in my good books.
Simon & Schuster
Overall Average Rating: 3.81
Simon & Schuster Publishers is the second least overall rated publisher. It's too bad because once upon a time, I used to think this publisher was the bees knees, until I hit a string of duds from them which has made me a bit more wary of them. Simon & Schuster is the publisher of one of my all-time favourite series, the amazingly well written The Monstrumologist by Rick Yancey. Without the inclusion of this series, my overall rating for Simon & Schuster would be quite a bit lower.
Overall Average Rating: 3.80
HarperCollins Publishers was my lowest overall rated publisher. Definitely a shocker because I swear HarperCollins books are always the ones that I get MOST excited about. I often have a hard time narrowing down my top choices when I do my quarterly HarperCollins Waiting on Wednesday Catalogue feature. Maybe it's BECAUSE my HarperCollins TBR is always the biggest and I read the most from them that I end up with a few more duds, whereas I am more selective when it comes to the other publishers? I don't know.
I would be interested to hear what you think about this! Have you ever broken down your average ratings by publisher before? Which publisher would you expect to come out on top? I was surprised with my results!
