A list of the 14 arranged pieces in Thomas's Pièces de salon, published by Augener in the 1890s, can be seen on the back page of 4 Duos, Op.108 (Lachner, Ignaz). Thomas's 23 item series of graded violin sonatinas: see list at Violin Sonatina in C major (Thomas, Emile). Worldcat lists arrangements and fantasias by Thomas copyrighted into the 1910s and works with input by Thomas released (these might be reissues, so double-checking is needed...) into the mid-1930s.
