Researchers have an almost unimaginable quantity of online resources to help with local and family history studies, these days.  And the historical materials grow rapidly with each passing year, creating treasure-troves of sources waiting to be harvested by inquiring types.

This information revolution makes volumes of virtual records easily findable, sharable, and accessible.  But this data explosion, which helps us better interpret the past, creates a new challenge, locating and managing the online resources.

Content curation tools help in this area.  They are generally cloud based personal information management systems, which have as a core function, organizing our higher quality resources.  You collect and add items into a cloud based library, which is available to anyone on the web.  Many of them function just like a bookmark, but it’s in the cloud, and some also provide additional resources, such as highlighting, notes, and better graphics.

I have set up a map curated resources page on a virtual site called liiist, to test one.   On this site, I have a page called Old Delmarva Maps.  As maps are one of those areas where we are seeing growth, there are now so many products available online, but unless you are regularly navigating the search engines and the key virtual archives, it can be hard to find the materials.  So I added links to maps from all over the Peninsula, which I use for research.  The idea is to help anyone working on a project find the better quality items.

I often find that I am helping genealogist, students, and local history researchers locate these materials on the Net so this is a way to more broadly share the e-collections.  On the site, you will find maps from all over the Delmarva Peninsula, from Claymont, DE and Bald Friar, MD. to Cape Charles, VA., and every point in between.  There are county and state atlases, Sanborn Fire Insurance Maps, large wall maps, coastal charts, topo maps, and lots more.

At this point, the titling convention I used for the bookmark headlines, in order to create some organization on the page for the first time visitor, was:  (1) MAPS — links directly to a cartographic products;  (2) Search – links to search engines and there are plenty of maps so be sure to search for anything that interests you; and (3) ARTICLES – posts about using maps.

I’m also looking at Pearltree, Diigo, and a few others, but want to test the social media tools to see which best help the local history and genealogy community.

I often need to access historical maps produced by the Office of the U.S. Coast Survey.  The agency started drawing charts in 1807 once President Thomas Jefferson created the division.  Over time the agency, now a part of NOAA, produced an enormous quantity of highly technical maps, including products that aren’t typically thought of as being part of this work.  As the first federal scientific agency the Survey produced land sketches, Civil War battle maps, and aeronautical charts.

These representations are helpful links to the past, but to review the materials one had to make arrangements through special repositories, such as the NOAA Central Library or the Library of Congress.  That changed, however, as a revolution in research methods got underway, allowing everyone to have easy access to resources on the World Wide Web.

The Division’s map and chart collection is a rich archive of high-resolution images capturing a vast wealth of the U.S. government’s historical survey and mapping.  The collection of over 35,000 scanned images – covering offshore and onshore sites – includes some of the Nation’s earliest nautical charts, city plans, and Civil War battlefield maps, according to NOAA.  Electronic copies are available for free download.

NOAA started assembling the collection in 1995 as a data rescue effort.  In time, as the web became more common, NOAA continued its preservation, while also increasing accessible virtually.

Today NOAA has an excellent portal for accessing the valuable products.  Visit the easy to use interface and type in search words or click on a spot of a map and many products around the Delaware and Chesapeake Bays will come up.

If you are looking for old maps on the Delmarva Peninsula, or anywhere in the nation, be sure to check out U.S. Topo Maps.  These valuable research tools show physical and cultural features of the landscape and contours of the land, beginning in the 1880s when the topographic program began.  Because the sheets are regularly issued, they are useful for tracing historical developments through time and for locating cemeteries, churches, roads, and other features.

Products run to current times as updates are now issued every three years.  And recently the U.S. Geological Survey announced that the newer ones have a crisper, cleaning design, which enhances readability for online and for print use.  This improvement process is ongoing but according to a press release redesigned sheets have been released for Maryland and Delaware.  All these resources are available for free download.

The place to start is with the national map locator.  On that site, a search for Wilmington, Delaware indicates that there is a cluster of over 20 products, starting in 1905 and running to the present.  Dover’s sheets begin in 1899, while those for Chesterton start in 1898.  You should find similar results for your interests as you search the products.

Check out the national map locator and downloader as there are lots of digital products there to help you with your local and family history research.   For a broader collection of works beyond topo maps, don’t for get to visit Old Maps Online, another excellent source.
