Updated 10 Nov 03:23 UTC. How these are worked out
FCC database
Look up any US amateur call sign: who holds it, what class, and the dates.
Vanity calls
Check a call sign, see who can apply for it, or list every open call of one format in your call area.
Study guides
Technician, General and Extra. These are the exams for a ham license. Each guide has every question in the current pool, with the answer and notes on the idea behind it.

The General Radiotelephone Operator License, the Marine Radio Operator Permit, GMDSS and ship radar. These are commercial licenses, not ham licenses.
