How the progress estimate works
The reading time tool gives you a rough estimate of how long it will take to read a book, based on its word count and a median reading speed of about 230 words per minute. This is an estimate—your actual pace will vary—but it helps you plan.
Books are grouped into four time categories: quick (under an hour), steady (1-3 hours), immersive (3-6 hours), and marathon (over 6 hours). With 39 quick reads and 11 marathons, there is a range to suit any schedule.
Steady Reads
Roughly 19 books take one to three hours. They offer enough depth to explore a topic without a huge time commitment.
Immersive Reads
About 24 books are immersive, taking three to six hours. These often provide a thorough treatment of a subject and are best saved for a longer sitting.
Marathon Reads
Eleven books are marathon-length, over six hours. These are substantial works, such as multi-volume histories or comprehensive surveys.
Making Steady Progress with the Reading Tracker
The Reading Tracker turns a reading goal into a concrete plan. It records progress in pages, not minutes or sections. You set a daily page goal, and the tracker estimates how many days remain. If a fixed catalog page count is unavailable, it estimates pages as ceil(word_count / 250). You can also replace that estimate with the page count from your own edition. This flexibility is useful because page numbers vary across formats.
Setting a Realistic Daily Goal
The default daily goal is 20 pages. That number works well for many readers, but you can adjust it. Consider The partnership of paint — Context and Discussion (295), a 13,013-word book. The initial page estimate is ceil(13013 / 250) = 53 pages. At 20 pages a day, you would finish in about 3 days. If you prefer a slower pace, 10 pages a day would extend that to 6 days.
The tracker calculates estimated finish days as ceil(remaining_pages / daily_page_goal). If you have 53 pages and a goal of 20, that is ceil(53/20) = 3 days. If you have already read 10 pages, your remaining pages are 43, and the estimate becomes ceil(43/20) = 3 days still, but the exact number depends on your current page.
Using Your Own Page Counts
The initial page estimate is a starting point. Different editions—paperback, hardcover, ebook—have different page counts. The tracker lets you edit the total pages to match your reading app or physical copy. This ensures that your progress percentage and remaining time are accurate.
For example, if your edition of The partnership of paint has 60 pages, you would enter 60 as the total. The estimated remaining time is proportional: estimated_minutes × remaining_pages / total_pages. With 57 estimated minutes and 60 total pages, if you have read 10 pages, remaining is 50, so the estimate is 57 × 50 / 60 ≈ 47.5 minutes. This proportional adjustment keeps your plan realistic.
Tracking Without an Account
Progress is stored in localStorage in your current browser. No account is required, so you can start immediately. The tracker remembers your current page, total pages, and daily goal each time you return. If you switch browsers or devices, the history does not follow, but for most readers, staying in one browser is convenient.
The tracker is a tool for planning, not a record of minutes read. It Catalogue maintenance uses source records and bibliographic context. By updating your current page regularly, you can see your progress and adjust your goal as needed.
