These scans of the indexes of tablets as contained in Taherzadeh's popular Revelation of Bahá'u'lláh series are intended to have two functions. One, these lists will let researchers know which of Bahá'u'lláh's thousands of tablets Taherzadeh discusses (see a larger list in the Leiden List). Two, they function as a working guide to authorized transliteration of these titles and thereby also indicate the original Arabic/Persian spelling. See also an article on transliteration.
Volumes 1-3 had a separate index at the back of the book listing just the tablets cited. Volume 4 listed the tablet titles in the book's main index.
