Land Mollusca of North America (north of Mexico) This is one of the most important works about North American land snails/slugs, and seeing that it has over 1000 pages, I think it would be suitable for a community collaboration.

Alternatively, the collaboration could be about all of Pilsbry's PD works. ”
