La Meri whose real name was Russel Merriweather Hughes, wrote a book on dance in which she interpreted the Chidambaram Karanas. Her collection of books and memorabilia has been acquired by the Indira Gandhi National Center for the Arts, Delhi. When made accessible to researchers, this material would provide valuable information on La Meri's sojourn in India and about Indian classical dance in the 1930's.

David Bolland is, perhaps, the only person to have a collection of Kathakali performances from the 1950s to the 1970s. These are preserved in a specially built studio adjacent to his house. His house in Brent Knoll in Somerset is called 'Malabar'. He is perhaps the only person who has a film clipping of the legendary guru Kunju Kurup (1881 - 1970). Bolland has made an hour long video film "The genius of Kalamandalam Ramankutty Nair" incorporating clippings from his Kathakali films from 1950-1983.

The temple sculpture in Kerala and the frescoes in the Padmanabhaswami and Mattancheri temple provide evidence of the fact that the basic Kathakali positions employed today were established by the 16th Century.
