Digitisation programme and restricted materials
The Institute’s digitisation programme, established in 2019 in partnership with J. B. Fowler (Precision Stimuli), makes selected collection materials accessible to accredited researchers in digital form. This page provides information on the programme’s scope, methodology, and access restrictions.
Digital Archive
Since 2019, the Institute has been systematically digitising archival materials in partnership with J. B. Fowler (Precision Stimuli). The digitisation process involves high-resolution spectral scanning, colour calibration against physical reference standards, and rigorous quality assurance against original specimens. Digitised materials undergo validation against perceptual equivalence standards established by the Perceptual Analytics Group (PAG-PAS-001) to ensure that the digital reproduction elicits response patterns statistically indistinguishable from the physical original.
As of the most recent audit, 3,204 of the Institute’s 12,847 holdings have been digitised. Priority is given to materials at risk of physical degradation and to those requested for remote research access. The digitisation programme is ongoing. Further information on the digitisation programme →
Restricted Access: Item IPS-ARC-2024-001
Access Restricted
One item in the Institute’s collection became the subject of institutional review in 2024. This item has been moved to enhanced restricted access pending further evaluation. It is no longer used in any active research programme. Access is limited to accredited researchers with institutional affiliation, ethics board approval, signed acknowledgment of material sensitivity, and a documented research purpose.
