Photographs and posters apart, the series includes Krishnan’s doodles and sketches of P Balaram. Although Krishnan was scarcely a diarist, eight of his diaries make up the bulk of this series. Like the diaries, the three calendars have scribbles and notes for to-dos and travel plans. A photocopy of his PhD certificate is the oldest item in this series under the ‘Certificates’ sub-series. The series also contains office log books (including one for feeding chameleon), conference tags, photographs of colleagues and friends, and posters found in his office.
