I’ve long been concerned about recommending mature material to an immature audience. This issue often comes up in my day job (see me at the public library). I’m happy to work with adults and guide these patrons to enjoyable reading. However, I still encounter those less than 18 years of age.
The ratings on various manga inspired the rainbow rating system. This is what I’ve got at this point.
Blue = General Audience
Green = Parental Guidance
Yellow = Parental Guidance for those under age 13
Orange = Restricted
Red = No way if you’re under 18
At this time, I won’t retrofit previously reviewed books. I may do so later.
