The Asuka DX Lunar 2: Eternal Blue Manga
A translation of the manga adaptation of Eternal Blue Remix. A few changes have been made in the game-comic conversion - read the notes at the start of the translation for details. (Very attractive character art, by the way - if you're a Lucia or Leo fan, I highly recommend this book.)
The Magical School Lunar! Manga, Vol. 1 & 2
A translation of both volumes of Hiroko Touda's retelling of the story of Magical School Lunar - very different from the game! Notes are provided at the beginning for the lost...
Also available out there is Seungtaek Choi's translation (the first ever Lunar manga translation, actually) of Younenki no Owari (Childhood's End), a manga set during the epilogue of Eternal Blue featuring the return of Xenobia, a prototype of Faithia/Phacia, and a strange young girl named Alice whom Hiro and Ruby meet. It's available in the manga's entry in the Books section of the Lunar Goods Archive. With the MSL manga done (and Vheen Hikuusen Monogatari over here), all the Lunar manga out there have been fan-translated.
Selections from the Lunar I & II Artbook:
"The Road to Lunar II" Plot Evolution
From the bottom of pgs. 82-87; a look at how the plot of the Mega-CD Lunar 2 evolved during production into its finished form. This is from where the Harmony team snatched the Dark Star plotline in the Four Heroes prelude.
(Also, man, there's a lot of graphic Ruby death in here.)
"30 Questions Concerning Lunar" Answered by Kei Shigema
Pgs. 109-111. As, though, the Lunar I & II book was published for in the Mega-CD era (and is set in that continuity), it could not foresee what would become the most burning Lunar question of all, which is: how could anyone write that scene in Harmony of Silver Star between Ghaleon and Day-Glo Jason Voorhees' Lite-Up Halloween mask and think it was a good idea?
"Lunar The Silver Star: Characters" Section
Pgs. 120-135; the short Lunar 1 section in the back of the book.
"Rong-fa's Days as a Priest Revealed" Short Story
From pg. 112; So I Almost Married an Axe Murderer. What strikes me most in this document is how sorry I feel for Leo.
Production & World Data Collections:
Akari Funato Lunatic Collection .PDF
Translation of a pot-luck .pdf Akari Funato put together containing much of her official, not-for-sale work on the Lunar games - the full-color SD manga series "Lunatic Parade" and "Lunar Carnival"; promo art for the Magic School games; layouts and rough sketches for the bromides Funato designed, including a few scrapped ones; and a good amount of commentary, including some inflammatory but true comments about the EBC cinemas. Information on how to obtain the .pdf is within, should you choose to brave my usually disastrous shopping recommendations that end with the merchant swapping the ISBN numbers or something.
Lunar: The Silver Star World of Lunar & Strategy Guide:
"Fundamental Data" & "Lunar Side Stories: The Untold Lunar"
From one of Tokuma Shoten's guidebooks, a short primer on TSS continuity and a look at a few bits of character backstory that didn't make it to the game. Contains a fact about Mel you will never be able to unread.
Megadrive Fan "A Closer Look: Lunar: The Silver Star in Review" Fan Poll Feature
Poll collecting reader opinions on several aspects of the game shortly after its release as well as Kei Shigema's reactions.
Eternal Blue Fan Book Doujinshi Japanese Lunar 2 Fan Survey
Published in the 1999 Eternal Blue Fan Book Japanese doujinshi anthology by the GARDEN GARDEN doujin circle. Unscientific, obviously, so don't go quoting this in your "Inventing the de Alkirks: Navigating the Stormy Seas of Interspecies In-Law Relationships" paper or anything.

And thus it was affirmed that the nation of Japan has no taste in men.
Doujinshi Text Translations:
Lunar 2 "Little Dragon" Doujinshi by Garden Garden
Short post-Lunar 2 doujin featuring Ruby and Nall. I have an extra copy, if anybody wants to trade.
SSS "Blue Moon Song 2" Doujinshi by Sora no Mori
Short Luhna & Arhes doujin. It's refreshing to have Arhes, not Luhna, as the dazzling love interest who needs protecting.
A translation of the backs of the ten cards that were packed in with the special MPEG edition of SSS. Not, of course, that anyone's particularly interested in these for the words...
Old list of bromide locations from EB Remix from the defunct Japanese fansite LUN@R, back when that info was driving a lot of people up the wall. Stored here for posterity.
