To summarize, I could say that Michael K. Buckland argues that information can be understood in three ways: as a process, knowledge, and a thing. Buckland focuses on the third aspect, emphasizing that tangible objects like documents and data sets can be considered forms of information. These "things" are crucial for preserving, transferring, and retrieving knowledge. In the field of information science, understanding these physical carriers of information is essential for understanding how information is used and managed.
