Originally published in 1881 The Household Cyclopedia of Knowledge was compiled from various contributors by Dr, Harshorne as a means of distilling the most useful skills, knowledge, instructions, and recipes of his time. This knowledge is what allowed people to live relatively comfortable lives, and it is the same knowledge that would be needed to survive when, not if, our society collapses. "In truth, the present volume has been compiled under the feeling, that if all other books of Science in the world were destroyed, this single volume would be found to embody the results of the useful experience, observations, and discoveries of mankind during the past ages of the world." Henry Hartshorne MD While there are many books on homesteading, prepping, and survival that provide similar information, few contain the completeness of the current work. They are further biased being written from the perspective of a technological age, while this book was written in a time before the light bulb and so uses technology that is practical and efficient according to the resources available to people of that time. Hard copies of this work are rare and fragile, while a PDF version is incomplete. By re-printing in hard copy allows people to easily store a copy in their homes that will be available when needed and does not rely on electronics to read.
