A list of Beier's 398 scientific papers was published, with an obituary, in Annalen des Naturhistorischen Museums in Wien. 252 were on pseudoscorpions. He described and named over 1200 pseudoscorpion species of which 1180 were still valid in 2007.
He was editor of the Orthopterorum Catalogus and an updated edition of the volume on insects in the Handbuch der Zoologie.
