Site map

Every part of fibub in one place, and how the parts link to each other.

How the pages connect

Each dot is a part of the site: Home in the middle, then the areas, then shelves and blog kinds, then subjects. Grey lines are the menus. Coloured curves are cross-links: tools listed as related across two parts (2,526 links), and blog articles that link to tools (1,083 links). Thicker means more links.

The 140 busiest cross-links are drawn. Tap a dot to open that part of the site; the tables below give every number.

About the site

Tool IDs and what we have

Every tool has a short ID, shown next to its name. Use it when you tell us about a tool, or type it in search to jump to it. The letter says which area it belongs to, and the number counts up with no gaps.

ID	Area	What it covers	So far
#T	Tools	Everything on the Tools tab: Science, Documents, Money, Everyday and Collecting.	#T1 to #T937
#L	Learn	School science and maths activities, Class 8 to 12.	#L1 to #L323

New areas get a free capital letter that can't be mixed up with another (never I or O). When the letter is already taken, the area gets a short code of a few letters instead, for example #TCH for teaching. Tools made before 10 November 2026 kept their old number too, so "#3" or "#1211" still finds them in search.
