Trying to define a “core” collection for theological libaries or a minister’s “book shelf” has a recurring effort among theological librarians. Mostly, we don’t experience the limits of portablity and the constraints of an unstable infrastructures for provision of electricity and Internet access. This article about the WHO’s effort to provide a core collection for of books and papers for medical practioners within the physical constraints of what can be packed into a Blue Trunk is an interesting challenge. What would we pack into the trunk for a minister in such an area?
The BTL is â€œa ready-to-use documentation moduleâ€?  of about 150 WHO and non-WHO books and manuals fitted into a blue metal trunk (Figure 1). The materials are arranged and filed in such a way that users can easily identify the ones that they need. Fourteen topics have been chosen using a basic classification code, e.g., General Medicine and Nursing (100), Community Health (110), and these codes are written on each filing box.
