----------------------------Original message---------------------------- Morning, this isn't so much a map library question as a geography department question. Has anyone seen maps of, or reports/thesis on artifical reefs in/on North America. Any suggestions would be appreciated. I would also like to thank all who responded to my query regarding care, upkeep, and scanning of globes. The student is busily following up numerous suggestions. Thank you in advance for any help.
