Winkler, A. (ed.) — Catalogus coleopterorum regionis palaearcticae.

1924-1932 In three volumes (complete). Double title pages, viii, 1698 p., half cloth with red labels on spines. In 13 issues as published, all with original printed covers bound in. Some pencil annotations. A very good set. The basis for every palaearctic Coleoptera-study, listing nearly 9,000 numbered species, not counting the varieties, which are indicated by letters. This is the special "annotation-copy". In this copy, the pages are deliberately half blank, to create room for annotations.
