About
About Book Series Insights
We are an independent site for readers who want two things at once: the right order to read a series, and the numbers behind it.
- 45reading guides
- 373published books tracked
- 31official sources
Why we built this
Most reading-order sites are lists copied from other lists. They tell you what to read next and nothing else, and when two of them disagree, there is no way to know which one is right.
We wanted the page we kept looking for as readers: every book in order, checked against the author or the publisher, and then the questions a book lover actually asks. How long did fans wait between books? Which one is the longest? How fast is this author writing now compared with ten years ago? Those answers were scattered or missing, so we started measuring.
Book Series Insights is the result: 45 guides so far, each one a checked list with the statistics drawn from it. We add series when we can verify them properly, not before.
What we believe
Sources before claims
A fact goes on the site only when an author, a publisher or an award body states it. If we cannot point to a source, we leave the claim out.
Numbers you can check
Every statistic is calculated from the list on the same page, and every chart says how. Nothing is estimated behind the scenes.
Calm, not loud
No pop-ups, no countdown timers, no walls of ads between you and the list. The design stays quiet so the books and the numbers lead.

How we work
Every guide follows the same four steps, so a page about a 1-book series and a page about a 35-book series are built the same way.
- Step 1Official source
The author’s site or the publisher’s catalogue.
- Step 2Checked list
Titles, years and formats, with upcoming books kept apart.
- Step 3Calculated statistics
Spans, gaps, growth and lengths, worked out from the list.
- Step 4Verified charts
Every chart notes its method, and every fact is checked against an official source.
What we build
Each guide opens with the count, the publishing span, the pace and what comes next, followed by the reading order itself. Below that come the charts: years between books, how the catalogue grew, story order against publication order, page counts where a publisher lists them, and how the series compares with the others on the site. The charts below are drawn from the whole catalogue as it stands today.

How we calculate
Every number on a guide comes from its list, using publication years. These are the measures you will see most often.
- Published books
- Every published work in the list. Upcoming titles and companion books are shown but not counted.
- Publishing span
- Calendar years from the first release to the latest one, counted inclusively.
- Average gap
- The years between the first and latest release, divided by the number of gaps between books.
- Longest wait
- The biggest gap between two books in a row, measured in publication years.
- Story order moves
- Books that change place when the series is read in story order instead of publication order.
- Comparisons
- Where a series ranks against the other series on this site, and an author against the other authors.
Page counts and reading time
Page counts are the numbers publishers list for one edition line per series, such as the first US hardcovers. The line is named under each chart, because hardcovers, paperbacks and later printings count pages differently, so books are only compared within the same line.
Reading time is an estimate from the reading speed you choose on the page.
Facts, sources and your privacy
Sales, translations, awards and age guidance appear only when a publisher, an author, an award body or a major news organisation states them, and every one of those facts is checked against the page that states it before it goes live.
