DPLA Announces Partnership with Rumsey Map Collection

The Digital Public Library of America (DPLA) is partnering with the David Rumsey Map Collection to provide online access to tens of thousands of significant historical maps and images. As part of the relationship, David Rumsey will provide metadata for over 38,000 maps and images, making the entirety of his notable online collection instantly accessible via the DPLA website and API­.



The Eagle Map of the United States. 1833. Joseph and James Churchman, Philadelphia. In: Rudiments of National Knowledge, Presented To The Youth Of The United States, And To Enquiring Foreigners, 1833.

A couple prominent examples of items from the Rumsey collections available through the DPLA are The Eagle Map of the United States, produced by Joseph and James Churchman, Philadelphia, 1833, (view on the DPLA), and the Map of Lewis and Clark’s Track, Across the Western Portion of North America, produced in 1814 (view on the DPLA). Other noteworthy items from Rumsey’s collections range from maps found in historic atlases to images of three-dimensional objects such as globes.

“I am very excited to have my digital library of historical maps added to the DPLA,” Rumsey said. “Maps tell stories that complement texts, images, and other resources found in the growing DPLA library. And the open content policies of my online library fit perfectly with DPLA’s mission to make cultural resources freely available to all. I see DPLA as reinvigorating the role of public libraries in educating children and adults in the digital age. I hope that my participation can serve as an example to others with private collections to share them with the public through the DPLA. Private collectors have always helped to build libraries and now they can do the same with digital cultural assets.”

“David Rumsey’s incredible collection of historical maps is one of the great private collections in the United States,” added DPLA Executive Director Dan Cohen. “What he has been able to assemble and make broadly available is simply astonishing. It is an honor to have these maps as part of the DPLA, and together to help others discover what their communities looked like in the past. We thank David for his generosity.”

Rumsey, President of Cartography Associates, a digital publishing company based in San Francisco, began building a collection of North and South American historical maps and related cartographic materials in 1980. His collection, with more than 150,000 maps, is one of the largest private map collections in the United States. In 1995, Rumsey began the task of making his collection public by building the online David Rumsey Historical Map Collection. Currently the online web site has over 38,000 high-resolution images of maps from his collection.

In 2009, Rumsey committed to donating his entire collection – both physical and digital – to Stanford University, which is currently creating an all-new Map Center to house it.

Rumsey’s online collection of maps is free to the public and is updated monthly. All of the online maps are searchable via the DPLA.

About the Digital Public Library of America

The Digital Public Library of America brings together the riches of America’s libraries, archives, and museums, and makes them freely available to the world. It strives to contain the full breadth of human expression, from the written word, to works of art and culture, to records of America’s heritage, to the efforts and data of science. The DPLA aims to expand this crucial realm of openly available materials, and make those riches more easily discovered and more widely usable and used. More information is online at http://dp.la.

Stanford Gives Howell Award to David Rumsey

On May 18, 2012, David Rumsey received the Warren R. Howell Award from the Stanford University Libraries in recognition of his service to Stanford. Fine press printer Peter Koch designed a commemorative booklet for the occasion:

New Geographical Search by MapRank Viewer

The new MapRank Search viewer enables geographical searching of the collection by map location and coverage, in a Google Map window. Pan and zoom the Google Map to the area of the world you want maps of, and the results will automatically appear as a scrollable list of maps with thumbnail images in the right side results window. The maps in the right side results list are ranked by coverage, with the maps that have coverage closest to your search window listed at the top. Maps lower in the list show the area of interest, but with coverage that does not match as closely. Mousing over any map in the list will show the map's coverage as a light red rectangle on top of the Google Map. Clicking on a map in the list will open it in the Luna Browser. You can filter your results with the When timeline, the What or Who keyword text window, and the Map scale windows, as well as search by place name in the Find a place window. Currently about 12,000 online maps are searchable with MapRank search; soon all the 27,000 online maps will be included. Launch MapRank Search.

Below is the MapRank Search viewer zoomed in to find maps of San Francisco, with the 1904 "San Francisco Intensity of Earthquake" map highlighted in red in the results list and with the area covered by the earthquake map shown in light red on the Google Map:

The MapRank Search viewer finding maps of San Francisco, California


Clicking on the thumbnail or title of a map in the list opens it in the Luna Browser with a zoomable image and description:

1904 "San Francisco Intensity of Earthquake" map image in the Luna Browser


Zooming out in the Google Map selection window instantly changes the search results to find maps with similar coverage, here the San Francisco Bay Area and Central California:

Zooming out from San Francisco changes the results list to show maps of Central California and the San Francisco Bay Area


Zooming out further in the Google Map window changes the map results again to maps of California:

Another zoom out level  finds maps of the State of California


Here the Google Map is set to find maps of the American West:

Maps of the entire American West are found with this Google Map window


Zooming out and panning east finds maps of the entire United States:

The Google Map window changed to find Unites States maps


Zooming out again finds maps of North and South America:

Maps of North and South America are show with this search view


Finally, zooming out to the full extent in the Google Map window finds maps of the entire World:

World maps shown in this zoom level


The WHEN time range line allows changing the dates of the results, here from 1690 to 1795 for the same set of World maps:

Using the WHEN time range to further filter results to World maps from the period 1690 to 1795


The Map scale boxes are used to limit the range of scales of the search, here set at 1:2,500 to 1:2.5 mil. This setting will show maps with smaller coverages that fall within the Google Map at the top of the list:

Maps of areas inside the Google Map are found by limiting Map scale at 1:2,500 to 1:2.5 mil


The Find a place box is used here to zoom the Google Map to find maps of Paris, France:

Using the Find a place box to zoom to maps of a place, here Paris, France


The WHAT or WHO box is used to further limit results to maps of Paris by Guillaume De Lisle:

Maps of Paris before 1795 by De Lisle with scale between 1:2,500 and 1:2.5 mil


Zooming out to show all of France finds maps by De Lisle of French provinces, still limited by time and scale:

Keeping the same limits of time, scale, and De Lisle, the Google Map is zoomed out and the results are changed again


Finally, keeping the same limits but panning the map to Italy finds maps of Italy by De Lisle with the same time and scale constraints:

De Lisle Maps of Italy from 1690 to 1795 with scale of 1:2,500 to 1:2.5 mil are shown


This new MapRank search interface allows geographical and spatial searching of the map collection in a dynamic and fluid way. It will provide an entirely new experience of exploring our online map library, using a map to search the collection instead of relying on textual terms alone.

While the new search interface is largely complete, please let us know if you find any errors or problems. The bounding coordinates for the maps are correct in almost all cases, but there may be some maps with incorrect coordinate (coverage) data - please let us know if you find any and we will correct them. The MapRank search interface and program has been developed by Petr Pridal of Klokan Technologies.

Landmark 1979 California Water Atlas Debuts Online

Originally published in 1979, The California Water Atlas, a monument of 20th century cartographic publishing, has been scanned and put online for free public access by the David Rumsey Map Collection. Linda Vida, Director of The Water Resources Center Archives of the University of California asked David Rumsey and Cartography Associates to scan and make available to the public this extraordinary book. The copyright holder, the California Governor's Office of Planning and Research, agreed to allow free public access online. 

The book was digitized at very high resolution so the resulting images can be explored, revealing all the amazing detail in the many diagrams, maps, and illustrations that accompany the extensive text. The original work was a collaborative effort involving many individuals in and outside the government of then Governor Edmund G. (Jerry) Brown, Jr., including William L. Kahrl, Project Director and Editor; William A. Bowen, Cartography Team Director; Stewart Brand,  Advisory Group Chairman; Marlyn L. Shelton, Research Team Director; David L. Fuller and Donald A. Ryan, Principal Cartographers; and many others who contributed to the project. 

The atlas may be viewed in three formats online: in the LUNA Browser of the David Rumsey online collection, in a Flip Book Reader at the Internet Archive, and in three PDF files, low (46MB), medium (72(MB), and high (180MB) resolution (For the PDF's, Firefox or Chrome are recommended since they support PDF progressive download; IE and Safari will download the PDF's but only show them at the end). All files can also be downloaded from the Internet Archive site.  When viewing the atlas online, it is best to use as big a screen as possible because the original book is large, 47cm high and 41cm wide (82cm wide when opened to two page view).

Use of the digital files is free for all personal, non-commercial uses, governed by a Creative Commons License. All the scanning, metadata creation, uploading to LUNA and to the Internet Archive was done by David Rumsey and fellow Cartography Associate colleagues Dan Holmes and Kristian McManus. 

"California Waterscape." Pages (70)-(71). Shows major cities and towns, selected water conveyance features, coastal salt marsh, wild and scenic rivers, and intermittent lakes and reservoirs. Has a table of Conveyance Features keyed to map.


When the atlas came out in 1979, it got rave reviews from both historians and scientists. Charles Wollenberg, writing in the California Historical Quarterly, called it "a very big and beautiful book...well-written, spectacularly illustrated, and filled with useful information for expert and layman alike...an indispensable sourcebook for decades to come." The Quarterly Review of Biology said it was "a major reference work of interest to applied ecologists concerned with water supply and usage and to ecologists in general in California." Over 30 years old, the atlas is still fresh and germane to today's issues and no doubt will be so for a long time to come.

Below are selected pages from The California Water Atlas:

            Front Cover of The California Water Atlas                                     Title page of The California Water Atlas
              View in LUNA Browser or in Flip Book Reader                            View in LUNA Browser or in Flip Book Reader


"Hydrologic Balance for California." Page (v).  A schematic diagram showing how "the hydrologic cycle is the natural system for recirculating water on a global scale"


"Annual Runoff and Seasonality." Pages(8)-9. Map of runoff including table of principal drainage basin areas. Diagrams of seasonal (monthly) variability in runoff for 33 streams in seven basins.


Infrared space image of the Southern Sierra Nevada and Owens Valley. Page 57.


"Measured and Unimpaired Streamflows. Water Year 1975." Pages (60)-(61). Graphically compares unimpaired and impaired monthly streamflows for numerous streams.


"Chapter 2. The Natural Endowment." Page 4. Image of wildfowl in flight over the marshlands of the Sacramento Valley.


"Crop Patterns and Applied Water." Pages (82)-(83). Maps of a 2 mile by 70 mile strip of land in Fresno County. Shows crop types and the amount of applied irrigation water.


"Chapter 3. The Advent of Human Settlement." Page 15. View of San Francisco in 1873 (by W. Vallance Gray & C. B. Gifford).


"Southern California Urban Delivery Systems." Pages (34)-(35). Shows water deliveries from the Colorado River Aqueduct, and the Los Angeles Aqueduct via Owens Valley; includes system longitudinal profiles. Includes table: MWD (Metropolitan Water District) Operations, 1974/1975.


"Peak Streamflows." Page(72). Large graphic showing annual Instantaneous Peak Flows for each of fifteen major streams from 1905-1976. Flood Recurrence Frequencies also shown.

Rumsey Map Collection Opens Online Map Library

The first home page of the David Rumsey Map Collection as it appeared on March 15, 2000

On March 15, 2000, the David Rumsey Map Collection opened its online library website for the first time.  With just over 2,000 images, the online collection represented a cross section of the larger physical map collection and included charts, globes, atlases, pocket maps, exploration books, wall maps, and geographies.  It had two viewers, the Insight Java Client - a downloaded desktop application - and the Insight Browser which ran in a browser window with no download.  Users found the site through Web search engines and several articles that appeared in the first month of operation - the site was chosen as Yahoo Pick of the Week (which brought over 10,000 visitors a day and nearly crashed the site) and it appeared in Wired Magazine, and D-Lib Magazine.
