So the first set is the set I read growing up. These are the books I read when I read each story for the first time. This set while it is not the prettiest or in the best shape, it is the most important one. It is the set that shows how much I loved the series and how much I have reread it because of all the wear and tear on the books.
This set contains books 1-4 in paperback. With Books 2 & 3 being first printing paperbacks. Books 5 and 6 are hardcover first edition/first printings. And my book 7 is the deluxe slipcase edition that I got the day it came out so it is also first edition/first printing.
Next is my UK set. This set is a mix of hardcover and paperback. Eventually I want to have a complete set of each, but that will take time since international shipping is outrageous.
It is books 3 and 5 that are paperback. Books 6 and 7 are first edition/first printings.
The next complete set I have is the new US special edition box set. I think this is the prettiest set available.
Then you have my pride and joy which is my first edition set. This set is finally complete. I finally found the second and third books in semi decent condition at used book stores. They are not pictured yet but when I have time, I'll update so you can see the complete set.
Book 1 is a first edition/11th printing, so not quite a full first edition, but I cannot afford a first printing at the moment. Books 2-7 are first edition/first printings though.
The final complete set I own is also my newest purchase and that is Harry Potter the Complete Collection, these are the new Adult hardcovers that have the awesome black and white covers with the bold colored spines.
Next is my audiobook collection. I currently only have 2 of the audiobooks physically but eventually I want to have all 7.
For the spinoffs, I have the US editions of Fantastic Beasts and Where to Find them, Quiditch Through the Ages, and Tales of Beedle the Bard.
For Tales of Beedle the Bard, I also have the US Collector's Edition. This book I have never taken out of the pouch and remains in the Amazon box it shipped to me in.
I then I have miscellaneous companion books that involve fan theories, the controversial Lexicon, and other fandom related books.
I then have 2 other UK editions of the first book. These include the New Adult Edition and the New Collector's Edition of Harry Potter and the Philosopher's Stone.
The New UK Adult Editions are the really colorful ones. This one has a pink/red spine to match the typography on the front cover. I also own Book 4 but it is not pictured at this time. Eventually I will collect all the paperback copies of this set.
This edition is hard to photograph, but the cover has gold embossing of the castle and the new cover font. As you can tell the slipcase is purple while the actual book is a bright orange. I know Book 2 is already out in this edition, I just have not gotten around to purchasing it yet.
Finally are my International Editions. I'm mostly collecting Harry Potter and the Philosopher's/Sorcerer's Stone in every language it was published in. I do have a few non-book ones though.
This is a paperback copy of the Spanish version of Harry Potter and the Philosopher's Stone which my mom picked up for me when she was in Peru.
This is a hardcover edition of the new cover Latin version of Harry Potter and the Philospoher's Stone.
This is a hardcover edition of the Japanese version of Harry Potter and the Philosopher's Stone. I found this one at a local used book store and was really excited!
This is a copy of the original cover Italian edition of Harry Potter and the Philosopher's Stone. I love the original Italian covers since they have these great cartoon illustrations on the covers. I eventually want to have all seven books in Italian.
This was the first international edition I owned and it was given to me by a friend when she was studying abroad in Budapest. This is the Hungarian edition of Harry Potter and the Sorcerer's Stone.
And finally you have my Ukrainian copy of Harry Potter and the Chamber of Secrets
International editions not pictured include: Irish and Korean
I also own the Illustrated Edition of SS.
