One more dictionary from archive.org to recommend

One more dictionary I came across recently: this one, entitled Pitman's dictionary of commercial correspondence in English, French, German, Spanish, Italian, Portuguese, and Russian from 1917. 1917 is fairly new as far as full-length books go on Archive.org, which makes the differences in orthography between this book and now less great than what you normally find there. Archive.org has quite a few technical dictionaries in multiple languages from around this time period, with hundreds and hundreds of pages of names for acids, barrels, chemical reactions and so on, but this one is useful in a non-technical sense as well.

Some of the entries (Spanish and Russian I didn't bother to put in):

Various usages of the words abandon and abandonment continue on for a great many entries, showing how useful this could be in expanding the vocabulary of an IAL such as Mondial or Occidental.
