"From 1950 to 1971, Astrid Lindgren wrote four books with Kati as the central character. The names of these books were Kati i Amerika (Kati in America) in 1950, Kati på Kaptensgatan (literally, Kati on Captaincy Street) in 1952, Kati i Paris (Kati in Paris) in 1954 and a final version of Kati's adventures which was a rehash of her own Kati på Kaptensgatan titled as Kati i Italien (Kati in Italy) in 1971.
