Web site Translated Memories seems to be the definitive resource for all things Silent Hill. They've gone to great lengths to localize and painstakingly composite the translated text onto a digital copy of "Lost Memories", the bonus series guide that accompanied Silent Hill 3's game guide.
In addition, they've also translated the other Silent Hill character and history resources "The Crimson Tome" and "The Sullivan Victims" from Konami's Silent Hill 4 official site, again only previously available in Japanese. While "Lost Memories" focuses on the entire series of psychological horror games, these two resources are simply backstory for the fourth game.
Every Silent Hill fan needs to bookmark this site immediately-and possibly print out a copy of the translated book for safekeeping. Michael McWhertor
