The Explicit-Formulas Database is joint work by Daniel J. Bernstein and Tanja Lange, building on work by many authors.

We've completely revamped the EFD
to include
more coordinate systems,
more formulas,
fully automated formula verification,
and fully automated operation counts.
**Latest news:**
The EFD also covers characteristic 2!

New paper on the EFD: "Analysis and optimization of elliptic-curve single-scalar multiplication", to appear in the proceedings of Fq8.

The old Explicit-Formulas Database is still available if you want to look at it.
