The boxed set has 3 booklets (Essential/Intermediate/Advanced) that cover all the grammar. Libraries usually have it.
I recommend them for the main romance languages and possibly German but for Slavic or Asian languages I would recommend other sources (I am barely intermediate in Russian and Czech and was trying Mandarin for a while).
