Book of Kells
By 1986, Swiss publisher Faksimile-Verlag had a process that used gentle suction to straighten a page so that it could be photographed without touching it. They got permission to publish a new facsimile. After each page was photographed, a single-page facsimile was prepared so the colours could be carefully compared to the original and adjustments made where necessary. The completed work was published in 1990 in a two-volume set containing the full facsimile and scholarly commentary. One copy is held by the Anglican Church in Kells, on the site of the original monastery.
