Animorphs was published in many countries internationally. For the original release, it was published in (at least) the US, UK, and Australia and in the following languages: French, German, Italian, Japanese, Dutch, Spanish (in Spain, Argentina, and the US), Portuguese (in Portugal and Brazil), Indonesian, Danish, Swedish, Hungarian, Greek, Norwegian, Finnish, Polish, Romanian, and Vietnamese. The 2011 re-release was published in the US, France, and Brazil.
In the US, Scholastic published books #1-54, Megamorphs #1-4, four Chronicles books, and Alternamorphs #1 and 2. The covers had the Animorph to animal morph on the cover, the "Animorphs" logo on the top, and the title and author on the bottom right. Each book also had an inside cover depicting the morphed animal in the environment in which it was used by the Animorph. The back cover had a summary beginning with "No one knows who we are..." for books 1-50. Books 51-54 has a different summary reflecting how dire the yeerk invasion situation had become at that point. Below that series summary, would be the summary for the specific book. This summary was usually the same as the summary for the book on the official web site (scholastic.com/animorphs) but the first 3 books had different summaries. The first seven books were initially printed with the "Animorphs" logo having a white background, and the title and author text non-shiny. For later printings of Books 1-7 and for the rest of the series, the Animorphs logo background, and the title and author text would be shiny. Starting with book 45 (which began the ending arc) all books until the end had the Animorphs logo on the cover with a black background.
"Scholastic School Market Editions" of the books were also published in the US. For most of these, the only difference was that in the middle of the book, there would be a stiffer piece of paper advertising the Animorphs Alliance fan club. The books containing this advertisement were the ones in the middle of the series from Book 20 to Book 38, approximately. If the book came with an extra item, such as Book 28 which came with bookmarks, the advertising would take the place of that extra. Some scholastic editions did not follow this trend, however - the Scholastic edition of Book 14 contained flipbook stickers you could put in your book. The Scholastic editions of Books 30 and 31 were half the thickness of the regular books, contained no inside cover, and had non-shiny covers, with no raised text for the Animorphs logo. The Scholastic edition of Megamorphs #1 and #2 were actually two books - the books were released in two parts to release the book faster. The Scholastic edition of The Andalite Chronicles was released in three parts, with three different covers. The scholastic edition of VISSER was simply the book published in paperback instead of hardback.
United States 2011 releaseEdit
In 2011-2012, Scholastic published books #1-7 in paperback, and Book 8 in ebook form, before the re-release was cancelled. The books had a lenticular card on the cover, so you could see the Animorph "morph" from human to animal via the lenticular format.
The UK books featured the title text in slightly larger font than the US books. They also did not contain inside covers. Books 1-54, Megamorphs 1 and 2, The Hork-Bajir Chronicles, and The Andalite Chronicles were published. Earlier books were released with a more plain background; later books, and later printings, had a multicolored background. Books 47-54 were published as combined editions: 47/48, 49/50, 51/52, and 53/54. Books 9,10,11,12,13, and MM1 came with character stat cards. The front of the card featured the half-human, half animal face that are on the cover of MM1. The back featured character stats that are the same (or very similar) to promotional trading cards that were given out around the same time Megamorphs #1 was released in the US.
These looked almost exactly the same as the US books, with the exception that the back cover had the australian animorphs web site url(www.animorphs.com.au) and the front covers were missing the "watch tv" logo that the US books had. Sometimes there would be a "As seen on ABC TV" sticker on the front cover instead.

The French books were published in France by Folio Junior. They had green spines, and a pink to blue color rainbow on the right side of the cover. The top of the front cover featured the promo image of a finger touching a lizard to "acquire" it. The back cover was usually the same as the US inside cover (with the book summary over it) for the Megamorphs and Chronicles books. For the numbered books, the back cover featured the four half human/half animal faces from the MM1 cover, and a book summary. These books do not have inside covers. Books 47-52 were not published in French. The Deception (Book 46) was "Volume 46" and The Answer (Book 53) was "Volume 47." MM4 and The Ellimist Chronicles were not published in French, but the other megamorphs and chronicles were.
French books were also published in Canada by Les Editions Scholastic. These did not have the rainbow on the right side of the cover (which is something the french publisher, folio junior, has on many books) and do have a small logo that says "Les Editions Scholastic" on the bottom left corner of the front cover.
France 2011 releaseEdit
Books #1-5 were published by Gallimard Jeunesse and the front and back covers were designed to look very similar to the American 2011 front and back covers.

(Full article: Japanese Animorphs Books )
Only Books 1-5 were published. These feature sketched morph covers in color, and are distinct images from any other publication. The inside of each book includes six black-and-white sketched illustrations.
These look very similar to the American covers.
All books #1-54, all four Megamorphs, and all four chronicles were published. The spines look similar to the American covers, and the front covers do as well but there is more space around the Animorphs logo.
Book #1-16, Megamorphs #1, and Megamorphs #4 were published in hardback by B. Wahlstroms and had the publisher's name in a green line on the top of the cover, and the title in large white letters on the bottom right.
Books #1-4 were published. The 'Animorphs' logo was written in Hungarian, so it looks like 'Animorfok.'
Books #1-27 were published. The covers look similar to the American covers, but the title is usually in yellow. Also, these are some of the few international books (other than the vietnamese books) whose translated titles do not match the American form of "The [noun]". For instance, the Book 1 title translates to "The Invasion of Aliens" and Book 26's title translates to "The fight on Planet Iskoort."
Bertrand Editora published at least books #1-8.
Books #1-15 were published by Rocco in Brazil and look very similar to the American covers as well as the Argentinian Spanish covers.
Portuguese (Brazil) 2011 releaseEdit

(Аниморфы) At least books #1-14 were published. The books look similar to the American books, but the 'Animorphs' logo is in Cyrillic script. The Playstation game 'Shattered Reality' and the PC game 'Know the Secret' were also translated.

- The only book to feature international covers with a different morph than the US cover was book 5, The Predator. The US cover featured Marco morphing gorilla, while many international editions (UK, French, Dutch, Spanish (Emece), Portuguese, Brazilian, Polish) featured Marco morphing lobster. Cover artist David Mattingly illustrated and designed both morphs. When Mattingly published morphing flipbooks of many of the covers to his youtube channel in 2011, the Marco flipbook video included both the gorilla morph and the lobster morph.
- For the original release, the Japanese covers were the only international editions to feature different cover art from the US covers. For the 2011 re-release, the Brazilian covers were the only ones different from the re-released US covers.
- Most of the international books do not have inside covers. The exceptions are German, Russian, Norwegian, and Indonesian.
