Den Haag, Martinus Nijhoff, 1939. 8vo (20.0 x 11.5 cm). 168 pp. Original green buckram with gilt title on spine and gilt vignette on front board. Top edge yellow. In original printed dustjacket.

This seldom-seen book is the index of Oort's "De vogels van Nederland" (Den Haag, 1922-1935, published in five volumes). It contains the common names of the birds treated in that work in Dutch, Latin (scientific names), French, Frisian, English, and German. A very nice, clean copy, still with the easily discarded dust jacket. Both the main work and this additional publication are rare. Anker provides a detailed collation of the main work but does not include this index. Anker, 381.
