Kalithogai contains one hundred and fifty poems and were written by various authors. Nachinarkiniyar, a Tamil scholar living during the sixth or the seventh century C.E. has annotated this work.
Kalithogai is an anthology of 150 poems in kali metre of varied length dealing with all phases and types of love experience. The poems are categorised into the five thinais according to the mood and subject matter conforming to the Sangam landscape. The first part (2-36) deals with paalai setting, the second (37-65) with kurinchi, the third (66-100) with marutam, the fourth (101-117) with mullai and the fifth (118-150) with neital. These five section were each written by a separate author. Perunkadunkon wrote the paalai songs, the poet Kapilar is attributed to the kurinchi, Ilanaagan the marutham songs, Nalluruthiran the mullai songs and the poet nallanthuvan the neithal songs. However, modern scholarship attributes the entire work to a single author.
Considering the style and usage of words, the work is also considered to be of a later period when compared to most of other Sangam literatures. The name of the compiler of Kalithogai and his patron are not known. The book of annotations for this book written by Nachinarkiniyaar in the mid fifteenth century says that Nallanthuvanaar compiled the Kalithogai anthology.
