One of his greatest contributions to the Estonian culture are his books on calligraphy and type design, that also give insight to the history of writing, different scripts and typefaces.
His book "Tänapäeva kiri" (1956) was adapted and remade for Latvian readers as "300 burtu veidi.
300 шрифтов" (1960) and for Russians as "Cовременный шрифт" (1966).
He has also published collections of his best calligraphy works.
American calligraphy magazine Scribe dedicated their issue of winter 1978 and spring 1979 to the works of Villu Toots.
