The purpose of this chapter is to introduce the information science reader to the wide
range of data and other resources that constitute “biological information”. Attention is
paid to both paper and digital sources and the use of digital libraries and
cyberinfrastructure for the creation, use, and re-use of information. The chapter discusses
various user communities and their needs, including scientists, educators and students,
policymakers, and other secondary users. The chapter concludes with challenges for data
sharing, preservation, and access.
