>A reading list made by a kind anon from these threads, and for these threads. Be sure to add stuff you're reading in here.
http://www.mediafire.com/?93atzwak7dx47- a Mediafire of documents and raw manga to get you started with reading
>A Japanese website that provides free (older) manga to read. Mostly tons of old stuff, but it has the entire set of Love Hina (http://www.j-comi.jp/book/comic/1) volumes, which is a pretty entertaining series.
>This takes a few dozen pages of actual manga, takes apart every single sentence and shows you how to translate them
http://www.fengyunzhibo.com/space/japan.htm (Chinese site with Japanese television stations. Good quality as well.)
>Another source for manga. You have to set up an account and make a post on one of their forums before you can access the Winny Club, which is where the raw manga is.
>Japanese subtitles for a ton of different anime shows. The only problem is that some of the subs seemed to be timed wrong when used with common raws (Ex: the Japanese subs are set for a 24 minute episode, while the raw is 22 minutes). So you might have to open them up with a subtitle editor and change the times. Regardless, you can usually use these subs with the anime you already have, just disable English subs and load the Japanese subs. For the anime subs, it's worth looking into using a text hooker to extract the text to make it easy to paste into Anki or a dictionary. (Such as AGTH)
