This chapter considers the affective potential through material circulation and reuse in the second-hand book market of College Street in Kolkata, India or the boipara. The boipara is a kilometre and a half long stretch of College Street in the northern part of the city of Calcutta (now known as Kolkata). This precinct is comprised of an extensive series of makeshift book stalls and book shops stretching in different directions. However, it is the sustained material attachment for second-hand books between booksellers and book buyers that provides a sense of well-being through care and kinship in the space. This chapter uses an example of material and affective interaction to demonstrate the multiple, circulatory relationship between second-hand book sellers, book buyers, book shops and book stalls that create forms of bonds, knots, and entangled attachments. I consider the ways in which the sensorial aesthetics of materiality of these interactions such as smells texture, musty tons of paper and personal notes on the books, facilitates a process of holding on and letting go of ‘books in motion'. I argue that these interactions provide a unique sense of resilience in relation to the space of the market through affective intensities of intimate love, collective care and attachment.
