It looks like I don't need to keep these original books, and I don't need to scan anything. Anyone who wishes to have the pages can get them from the internet. A little bit of exploring brought these links to light: The Boy Mechanic: Book 1, 700 things 16,343k (Google Books) https://archive.org/details/boymechanicthin00cogoog The Boy Mechanic: Book 1, 700 things 17,760K (Gutenberg Project) https://archive.org/details/theboymechanicvo12655gut (I'd go with the Google Books version of Book 1. Gutenberg Project re-typesets the whole thing and pagination is lost.) The Boy Mechanic: Book 2, 1000 things 32,308K https://archive.org/details/boymechanicbook200chic2 The Boy Mechanic: Book 3, 800 things 33,083K https://archive.org/details/boymechanic03popu What I had in mind in the beginning was a small book with a title something like /The Boy Mechanic Maps the Neighborhood//. / Included in it would not only the cartography articles but also the articles about making the tools and whatever can be found about tricks with math (I found at least one). Someone else would have to do it, though, because I lack the software to take the PDFs apart and re-assemble the articles into a single document. In an ideal world, the whole thing might be tested by a school, and the testing managed by someone who's on this list. Does anyone know of a middle-school administrator who'd like to work with this idea?
