I just published a PDF-file containing the catalogue of the famous Ridder collection belonging to the Bibliothèque nationale in Paris - whose content could be checked and partially downloaded via Gallica.

Please follow the link given below and at the bottom of the page you find the link named "Download".

Thank's a lot to our good friend Yves Martin who's made a copy of the catalogue and allowed its publication.

Kind regards from Germany
