In the US, Associated Press style is ''advis'''er''''', and most newspapers and some magazines follow that spelling, whereas US federal government style, other government agencies, and many businesses prefer ''advis'''or'' . News organizations around the world may change spelling found in sources, even in quoted material. US book publishers may be less likely to change spelling in quoted material because this practice is contrary to ''The Chicago Manual of Style .
