Geologic History of the Moon

Thanks to Ton Baten, a fellow lunar observer from the Netherlands I’ve found a link to an online paper about Geologic History of the Moon by Don Wilhelms. This is great news for all lunatics because this paper, which is considered as one of the most important publications on lunar geology, is out of print and only available online. The book is divided into 18 PDF files. Follow this link and start downloading!. Thanks again Ton!
