E.W. Lane's Arabic-English Lexicon (8 parts, London, 1863-93) is a major Arabic-English dictionary based on 112 sources, mostly medieval ones, along with al-Zabidi's Taj al-Aroos (also included in Lisaan.net). Lane died before he could finish the work, his great-nephew Stanley Lane-Poole finished it, publishing Volumes VI, VII and VIII from 1877–1893 using Lane's incomplete notes. Lane-Pool's work is of lower quality than Lane's. The work of Reinhart Dozy (see below) was meant as a supplement to Lane's work that covers modern Arabic (Lane focused on classical Arabic only).
