Odom OSPF LSA types

Wendell Odom describes the two main types of LSAs as:

Router LSA: Includes a number to identify the router (router ID), the router's interface IP addresses and masks, the state (up or down) of each interface, and the cost (metric) associated with the interface.

Link LSA: Identifies each link (subnet) and the routers that are attached to that link. It also identifies the link's state (up or down).

I follow him for the Router LSA but the Link LSA has me wondering what the hell is is talking about. Unsatisfied I go on youtube and Kieth Barker has a more detailed explanation that makes more sense.

So can anyone clear up what he means by a Link LSA, a Link Link State Advertisement???
