The availability of Tezuka in English

I do love Osamu Tezuka's work, but some of his titles are rapidly going out of print. Here's what you can (and can't) find; links go to the Amazon.com page for the first volume of each series.

Easily Available
The following works can be found on Amazon and similar retailers new or used for about their original price (or less!):

Adolf -- The story of three men named Adolf during World War II. Please forgive the cheesy covers.

Apollo's Song -- A cautionary tale about violence and sexuality, this is one of Tezuka's stranger stories, in which a violent young man is forced to live through multiple tragic lives to learn compassion.

Astro Boy -- Tezuka's most popular work, and one of his most light-hearted. Astro is always an easy read, though it frequently touches on difficult subjects like bigotry, aggression, and obsession.

Ayako -- Just released. Haven't read it. Has a naked woman on the cover.

Buddha -- A biography of Buddha's early  years, light on the mysticism and heavy on the realism.

Black Jack -- The story of a miracle-working doctor, Tezuka wrote Black Jack while he was redefining his style in response to the serious gekiga movement. As a result, Black Jack deals more directly with modern themes and problems, like obsession with everlasting life and beauty.

Dororo -- Only 3 volumes! Granted, Dororo begins with a silly premise: a man promises his unborn son's limbs and organs to various demons; the half-living lump of his son is abandoned, then rescued by a surgeon who gives him enough prosthetics that he can function. But this gives rise to a classic samurai story, as the young man crisscrosses the countryside in search of these demons.

Metropolis -- Inspiration for the relatively recent film, this is one of Tezuka's earliest works, and it shows. Only one volume, and it's starting to rise in price on the used book sites.

Lost World -- Another early Tezuka work. Mostly action/adventure fun.

MW -- Tezuka's musings on why bad things happen to good people. An almost absurd amount of tragedy and evil occurs in the pages of this single-volume work.

Nextworld -- Yet another very early Tezuka work, a rollicking adventure story that touches on a few grander themes.

Ode to Kirihito -- I haven't read this one yet. It's about a guy who contracts a disease that turns him into a monster, so it's a full-scale horror story.

Mixed Availability
Phoenix -- Tezuka's masterpiece, spanning millions of years and a breathtaking array of characters and situations to probe the mysteries of the human spirit. The first volume of Phoenix now goes for hundreds of dollars (U.S.), and others are rising in price, but most are available for $12.

Hard to Find
These titles are hard or impossible to find, even used.

Crime and Punishment -- Released in 1990 as a bilingual manga; now well out-of-print and unavailable even from used book sites like Alibris.g

Princess Knight -- The first shoujo manga.

Swallowing the Earth -- Another one I haven't read yet, it's apparently a slapstick story about the world's dependence on the gold standard, mixed with quiet points about modern sexuality and other social issues. Color me intrigued.

And of course, this post only lists those few of Tezuka's works that have been published in English; the man produced hundreds of manga.

Anything else I should add? Let me know in the comments below. Thanks!
