Browsing by Category
Categories let you find books by broad topics like Fiction, Theology, or Children’s. Every book on Agathos Books is automatically assigned categories based on its metadata, so you don’t tag them yourself — you use them to discover books.
For a quick overview of how categories compare to collections and tags, see How books are organized.
Where Categories Appear
Section titled “Where Categories Appear”On the Browse Page
Section titled “On the Browse Page”Tap Browse in the navigation. Below the search bar, Browse Categories rails surface books in each category — Fiction, Biography, History, and so on — pulled from your connected libraries.
Tap a category title or a book inside it to see all matching books.
On a Library Page
Section titled “On a Library Page”Open a library and scroll past the Collections strip. Each library has its own set of category rails so you can see what’s available in that specific library, organized by topic.
When Filtering Your Collection
Section titled “When Filtering Your Collection”- Go to Collection
- Tap Filter
- Pick one or more categories to narrow the view
Combine categories with other filters (favorites, ownership, reading status, your own tags) to drill down further.
Why a Book Might Show Up in an Unexpected Category
Section titled “Why a Book Might Show Up in an Unexpected Category”Categories come from book metadata, so a single book often belongs to several at once — a Christian biography may show up under both “Biography” and “Christian Living,” for example. If you can’t find a book where you expect it, try a related category.
Categories vs. Collections vs. Tags
Section titled “Categories vs. Collections vs. Tags”Quick refresher — they’re easy to confuse:
- Categories (this article) — automatic, platform-wide, topic-based
- Collections — curated by a library admin, scoped to one library
- Tags — your personal labels on your own books
