Head and Tail Lists Collection of items where the primary access (or addition or removal of items) is at one end of the list or the other. Common terms are "stacks", "queues", "LIFO lists" "FIFO" lists.

Lists and Sets Data structures implementing lists and sets.

Trees and Graphs Data structures implementing Trees and Graphs. (Each element references 0 or more other elements)
