The Heezen-Tharp collection: Arctic Ocean collection is open to research. Researchers are advised to contact the Geography and Map Reading Room prior to visiting. Many collections are stored off-site and advance notice is needed to retrieve these items for research use.
Researchers wishing to cite this collection should include the following information: Container number, Heezen-Tharp collection: Arctic Ocean collection, Geography and Map Division, Library of Congress, Washington, D.C.
Consists of some 370 items related to Heezen and Tharp's mapping of the Arctic Ocean floor.
Important note: Each Group has a corresponding Holdings Number that can be located in Voyager by Library staff members. Item(s) filed within each Group have a corresponding Barcode number that Library staff members can locate in Voyager to retrieve it from Ft. Meade.
Some Groups or titles within Groups are labeled n/a. These items either were anticipated for acquisition in early processing stages or discarded at a later stage.
The Heezen-Tharp collection: World/Miscellaneous is organized in seven series:
The following terms have been used to index the description of this collection in the LC Catalog. They are grouped by name of person or organization, by subject or location, and by occupation and listed alphabetically.
