Chwolson's reputation for vast learning and critical acumen was occasionally vitiated by his proposals of bold hypotheses feebly supported by historical facts. It was probably his predilection for such stances that led him to persist in defending the authenticity of some of Abraham Firkovich's forgeries, even after they had been fully exposed. Chwolson was a diligent collector of Hebrew incunabula and rare books, and his essay on the beginnings of Hebrew printing, Staropechatnya yevreyskiya knigi (1896; Reshit Ma'aseh ha-Defus be-Yisrael, 1897), is still useful. He published a catalog of his library, Reshimat Sifrei Yisrael (1897), and supervised the publication of the early fascicules of S. Wiener's catalog of the Friedland collection of Hebrew books in the Asiatic Museum of the Russian Academy of Sciences (1893– ). His own rich library was given to the same museum.
