• Event: INTACH lectures (#52).
• Organization: INTACH, Indian National Trust for Art and Cultural Heritage.
• Lecture: Reversibility in book and paper conservation.
  It is in fact a revisiting of the same lecture given at the Cores Symposium, organized by Syntrawest, Vlaanderen Departement Cultuur, Jeugd en media
• Abstract:
  Is reversibility a guarantee for good conservation?
  Should it be our main goal, as conservators?
  A discussion of this controversial issue seen form several points of view:
  – Physical phenomenon (solubility, and others).
  – Theoretical point of view (revert along time).
  – Linguistics (is it the right word?).
  A few examples will illustrate to what extent can we apply these theoretical aspects in the conservation practice, seeking to get a final conclusion that replies to the first given questions.
