Today, as a digital center, accessing and acquiring data through digital devices is gradually pushing the value of analog data out. As a result, the concept of libraries, bookstores, and bookbinding books has changed naturally. In the case of second-hand bookstores, analog data is the main subject, but because the data is not organized, it is hard to find the book that people want. Here, you need to digitize and catalog the inventory of each store and make it easy for people to find the book they want.\nHowever, the elderly people who are hard to acquire and utilize this information maintain their stores, and as a result, many old bookbinders are closed, and the long - standing history of Bosu-dong bookstore is also declining. The purpose of this study is to introduce data systemization education to merchants as a non-architectural part in order to solve the essential problem of Bosu-dong bookstore alley, and to promote mutual communication between merchants, residents and tourists I want to be smooth. To do this, we want to apply the concept of a Rhizome. In other words, as an architectural method for the activation of bookstore alleys. We analyze the characteristics and present spatial and programmatic solutions that apply the derived results. In addition, we propose a new library proposal that incorporates Rhizome theory into the Bosu-dong bookstore alley.
