The Do It Yourself (DIY) section is an essential and well-used part of the public library's collection and must be kept up-to-date to remain valuable, since tools, materials, and building codes are always changing. Current economic decline has increased the topic's popularity as homeowners choose to remodel rather than buy, or attempt to make repairs themselves to save money. Online tools and video are among the most useful formats, since their information is regularly updated. They can often be short and specific, and watching a repair being made can make the information more easily understood. But many patrons will welcome books that give them a more in-depth grasp of their project. This article focuses on materials designed for the homeowner rather than the professional builder. A section on the "green" approach to DIY is included in this article, as this is a subject of growing interest to many people. Suggested journal titles are also included.
