Van Leeuwenhoek's primary journals are found scanned within this 516 page eBook. For me, far aside from content... I would use this resource when coaching students on interactive science notebooks. His handwritten/drawn documentation is still a model today. To day we could use a digital camera, back then... he WAS a "camera." So cool.
