Amanuensis is a search tool for the juristic sources of Latin Antiquity, including the Corpus Iuris Civilis, the Codex Theodosianus, many pre-Justinianic authors and several Germanic law codes. Amanuensis uses, by courtesy of Hofrat Dr. Josef Menner, an enhanced, capitalized Romtext database.
By courtesy of Dr. Ingo G. Maier, Amanuensis additionally includes the Latin novels plus a comprehensive of collections of unabridged constitutions which happened to be transmitted beyond the codes.
Leg.Nov.gr. and Greek CJ were added by courtesy of Prof. Dr. J. E. Spruit thanks to the assistance by Projet Volterra (British Academy).
Note that most juristic sources are absent from PHI and LLT, so it is indeed worthwhile to have Amanuensis.

What are the advantages of Amanuensis when compared to earlier Romtext search software?
Besides other things:
▪Works on modern operating systems
▪Very fast searches
▪Updated database: includes capitalization and, for Greek passages, polytonic Greek
▪Complex searches using logical and truncation operators such as +, -, *
▪Automatic handling of prefix assimilation ("exerat" finds both "exserat" and "exerat“)
▪Hits are highlighted in color
▪A double-tap takes you to the context
