Upoštevajte, da v državah, ki ne uporabljajo pravila krajšega trajanja in v katerih traja avtorskopravno varstvo dlje kot za življenja avtorja in še 60 let, to delo morda ni v javni domeni. Konkretno traja varstvo v Mehiki še 100 let, na Jamajki še 95 let, v Kolumbiji še 80 let, v Gvatemali in na Samoi še 75 let ter v Švici in Združenih državah Amerike še 70 let.
