Tool libraries were around since the 1970s : a storage and workshop depot where the best work and repair tools for carpentry and building would be stored by a master craftsman and shared among those in need in the town when repairs were needed. Today, just when the sharing economy is becoming the best and strongest model for self-sufficient communities, Tool Sharing is again becoming a way of life among advocates of community development. DIY and a sharing economy drive people to pool resources than out buy each other and possess everything.
