The U.S.G.S. Quadrangle maps available here are original prints obtained over time and not digital reproductions which are available at U.S.G.S. today. Many South Coast maps are duplicated with different dates reflecting map updates.

Reproductions of these maps are printed on a lighter bond paper than the original printings.

The Quad Sheets are in used condition and many maps have some wear with edge tears corners missing, creases at fold points and some markings with pen and pencil.

There are Special issues and Specialty maps included in list attached.
