The book describes the historical evolution of the book index and concordance. Some interesting historical episodes. Funny to see some of the arguments against indexing. E.g., with an index, no need to actually read the book.
One takeaway is that current search algorithms (Google, et al.) are poor compared to human-created indices. Some AI approaches may help, but they’re still poor.
I was disappointed in the book. A lot of the history was not interesting,
TODO: I could write more.
