April 2005, National Nuclear Data Center, Brookhaven National Laboratory.

Ground-state properties for every known nuclide: half-life, spin and parity, decay modes and branching, abundance. Designed to be carried.

The name is the charm — wallet cards for 115 pages of nuclear structure data. It is the periodic table’s much larger and less famous cousin, and it is free.
