Op Ontdekking in het Maanland
A.J.M. Wanders: Op Ontdekking in het Maanland (1950)(glossary entry)
An interesting guidebook in the Dutch language, made by one of the most dedicated popularizers of lunar and planetary observing.
Should be re-printed and translated to English, French, German, Russian, etc... etc...
This book contains a curious map of the moon's near side in four quadrants (south up, north down). Curious because all the craters are khaki-green colored, while the mare regions are a soft light-green colored. Strange to say, Giovanni Baptista Riccioli's discontinued TERRA nomenclature was also included (these so-called Terra regions are colorless white), and there are also some of Johann Nepomuk Krieger's and Rudolf Konig's odd names at the Carpatus mountains. This map (the four quadrants) is a goldmine for those who want to investigate a diversity of discontinued lunar nomenclature.
See also the Exploration and Investigation of Riccioli's Terrae regions, with additional notes.

A.J.M.Wanders was perhaps the first one who discovered the existence of the lunar formation which is unofficially known as Gardner Megadome. He called it "f", see page 301, Figure 115. See also Quadrant II of the green-colored map at the end of the book.
