If you have a need for bookshelves in your office and a bit of a Do-it-Yourself prowess, there is no reason why you cannot build your own bookshelves. Many people tend to take care of items that they have built better than items that they buy from their local big box store. Another advantage is that you are not limited to any set design, you can build your shelving system as big or as small as you want, enabling it to fit in any space that you desire. Your bookshelves are also likely to last longer since most people who build their own tend to build them out of strong wood rather than particle board, which is common in manufactured items. If you are ready to build your own shelves, here are the typical materials you will need and basic instructions on how to get started.
