Evaluate the challenges of digitising and authenticating heritage records, with examples.

Heritage records — films, photographs, manuscripts and official files — are the documentary memory of a civilisation. India has made real institutional progress in digitising them, but authentication, format obsolescence and a legal framework limited to public records leave the effort incomplete.

Achievements that must be credited

• National Film Heritage Mission: ₹363 crore outlay for the world's largest film restoration project at NFDC-NFAI, Pune [1]; 1,469 titles (4.3 lakh minutes) digitised [2].
• National Archives of India: a 30-crore-page digitisation project begun in 2024; Abhilekh Patal hosted 18.23 crore pages by February 2026, with download charges reduced [3].

Challenges in digitisation

• Scale and backlog: The Hindu's photo archive holds about 2.5–3 million images, of which only ~60% of physical prints, negatives and transparencies were readily available digitally — leaving roughly a million to hand-search [4].
• Machine obsolescence: the UNESCO–IASA Magnetic Tape Alert Project warned that vanishing playback equipment makes routine transfer of magnetic carriers impossible beyond about 2025 [5].
• Recurring cost: digital film records are costlier to maintain than celluloid, since files need perpetual copying and migration [6].
• Coverage gap: private photographic collections fall between NFAI (films) and NAI (public records).

Challenges in authentication

• Provenance depends on publication: the "Madras on Stage" exhibition dated photographs only by cross-checking news items in The Hindu and Sport & Pastime (1947–68) [4]; unpublished negatives often stay undated and unnamed.
• Selection bias: famous performers were printed and can be verified; folk and small-town artists were not, so the record remembers unequally.
• Legal vacuum: the Public Records Act, 1993 binds only public records; Section 11 permits merely voluntary receipt from private sources [7].

Digitisation in India is therefore well-funded but narrowly scoped, and authentication remains its weaker half. The way forward is a national survey of private cultural holdings, mandatory metadata capture at the point of scanning, and a deposit-and-grant incentive that buys public search access while leaving copyright intact — giving practical content to the fundamental duty under Article 51A(f) to preserve our composite culture.
