sentences:  Thus the work has never been completed.Lane's work focuses on classical vocabulary, thus later scholars found it necessary to compile supplements to the work for post-classical usage, such as the "Supplément aux dictionnaires arabes" (1881; 2nd ed., 1927) by the Dutch Arabist Reinhart Dozy; also, the "Wörterbuch der klassischen arabischen Sprache", being published from 1970 onwards by the Deutsche Morgenländische Gesellschaft, starts from Kāf, thus supplementing Lane's work in effect.The first draft of the lexicon, as well as the whole "Taj al-ʿArus" copied by Al-Dasuqi for Lane in 24 volumes, are now preserved in the British Library.
