How the book series pages are made

How the ages are chosen

Where a publisher's own page gives an age for a series, the page shows that age and names the publisher. Where none we could open gives one, the age is Peabody's own estimate, from our kids' lists and what is in the books, and the page says so in those words. Today 23 ages are a publisher's and 25 are our own. A bookstore's or a review site's age is never passed off as the publisher's.

An age on a book is about what is in it, not how hard the words are. So every series page also says, in one sentence, what reading it is like (“short speech bubbles, a joke a panel”), and a short note on what is in the books: chases, potty jokes, sad parts. It is never a verdict: you know your child.

What we leave out on purpose

No covers, no blurbs and no character art: those belong to the publishers and illustrators, so a series card is text, a number and an age. No reading-level scores, which belong to the companies that make them. No prices, no shop buttons and no affiliate links, and nobody paid to be listed. The manga here are only series sold for children, and trademark-heavy licensed manga stay out.

What stays on the device

The ticks on every checklist, My shelf and its NEW badges live in this browser only. Nothing is sent to Peabody and nothing is tied to a name. What should I read next? asks three questions answered with three boxes, so a child never types, and keeps no answers. A shared shelf link or QR code names series, never ticks. Clearing the browser's data clears it all, so print the reading log if it matters: one page, a row of boxes per series, a “Finished on” blank.

Manga, right to left

Some manga are printed the Japanese way: you open what looks like the back cover and read each page from the top right. The manga page has a five-step how-to, and each series page says which way its English edition reads.

For teachers

The classroom comic kit: six lessons for grades 2 to 5, each a one-page plan and a student sheet to print for the class. No student data and no class login.

The dataset

Every book, in order, with its series, number, year, release day where one matters, and the series' age with whose age it is: series.json and series.csv. Licence: CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/): free to reuse with a link to https://peabody.kids/series.

Something wrong, or a question?

A count drifts the day a new book comes out, and a publisher can move a day. Write to the address on our about page with the page and what is wrong; we check it against the source and fix it. The best questions join “Asked by families” on the series page. Checked October 30, 2026.
