A Simple Method for Analyzing Books

A recent Pew Research Center study found the following:

  • Americans 18 and older read on average 17 books each year. 19% say they don’t read any books at all. Only 5% say they read more than 50.
  • Fewer Americans are reading books now than in 1978.
  • 64% of respondents said they find the books they read from recommendations from family members, friends, or co-workers.
  • The average reader of e-books read 24 books (the mean number) in the past 12 months; the average non-e-book consumer read an average of 15.

The first bullet above is pretty remarkable. Using 17 books/year with, let’s say, 40 years of reading (above the age of 18), that’s 680 books read in adulthood. That’s a lot.

This got me thinking about how we decide which books to buy and how our decisions on which books to buy adapt with each book that we read. Are we in tune with our changing desires and interests and is our feedback loop from both positive and negative reading experiences, well, accurate and efficient?

Some time ago, I began collecting data on my book reading experiences to allow me to analyze exactly that. Given the Pew study, I figure I’ll share my methodology in hopes it makes sense to someone else. Star ratings such as that on Amazon are certainly helpful, but my hope is to perfectly understand what works for me as to make my decisions on reading material accurate, efficient, and part of a lifelong journey for knowledge and inspiration.

Known Data Elements (Both Categorical and Quantitative)

  • Author
  • Type (Non-Fiction vs Fiction)
  • Genre (Thrillers/Suspense, Science/Technology, Current Affairs & Politics, etc.)
  • Number of Pages (using hardcover as a standard)
  • Date Published

Personal Data Inputs (upon book completion)

  • Date Completed
  • Tags/Notes
  • Readability, Flow, & Structure (RFS) – A score ranging from [0.0, 5.0] subjectively assigned to a book based on ease-of-read and the overall structure of the book.
  • Thought-Provoking, Engagement, & Educational Value (TEV) – A score ranging from [0.0, 5.0] subjectively assigned to a book based on how mentally stimulating it was in terms of knowledge and thought.
  • Entertainment, Suspense, & Likeability (ESL) – A score ranging from [0.0, 5.0] subjectively assigned to a book based on the entertainment value and overall likeability of the story, characters, and/or information presented.

Those three metrics (RFS, TEV, ESL) allow one to create a overall score for the book. My overall score is a simple sum of the three metrics, divided by the maximum possible score (15.0), and expressed as a percentage (ranging from 0% to 100%). Although I have not yet conducted any correlation studies or categorical analyses using my data (which I have for 42 books starting in Aug 2004), below is a snapshot. As for my next book, it’ll probably be a self-help guide to drop the data obsession. 🙂
