Research Paper Maps Of Ohio


Maps are found in a wide variety of materials throughout the library: as single sheets in a map collection, as government publications, as plates in atlases, as illustrations in books or journals. Digital maps are found on any of numerous web sites, in online research collections, or can be dynamically generated using online mapping services. Just as in written work, ethical scholarship demands that the source of information be cited.

When maps are used as part of a document, like maps you might include in a scholarly assignment or paper, the maps must be referenced (cited) in two places:

First, maps must be given a caption. Typically, tables, figures, or maps are labeled with a sequential number in a document (e.g. Map 1, Map 2, etc.). They are given a short caption, which briefly identifies the source and contains a descriptive title. These captions follow specific style. When maps are identified in this way, it is possible to easily refer to the map in the text (e.g. population densities, as shown in Map 3, continue to...). This is one form of inline citation and is the form used in Geography 222.

Brief inline citations allow the reader to refer to a reference list (or bibliography) to find out more information about the source of a map. All scholarly papers contain a reference list. This second citation is where complete documentation and credit for an information source is given. Reference lists also follow a specific style. The style used in Geography 222 and by most scholarly journals in Geography is called Chicago Style, taken from The Chicago Manual of Style, 14th ed. While all Chicago Style citations follow a similar form, there are specific differences based upon the source of the material.

Citing Maps from Print Sources

When creating citations, it is important to follow the form as precisely as you can. Here are some Rules of Thumb:

  • If the author or editor of a work cannot be determined it is okay to leave it out.
  • If the map does not have a formal title, you will have given it one for your caption. Use this derived title for the map title and place it brackets [ ] to indicate it is a derived title.
  • The format of works like maps must always be specified in brackets [map].
  • The scale must be documented if known and if the scale is not known, you must use the phrase "Scale not given".
  • Edition numbers are used only for editions newer than the first, e.g. 2nd ed., 3rd ed., and the word edition is abbreviated to a lower case "ed."
  • Volume numbers are expressed as just the number, e.g. 3.
  • The date may or may not be encased in ( ), pay attention to the form.
  • Page number(s) may or may not include the abbreviation "p." Where necessary, the range of pages is given.

Citing Maps from the Web

In your work, you will be using two kinds of maps obtained through the web.
The first kind of map is a static digital map. This is a map that you might find in a digital map collection. These maps are pre-existing, scanned images and are not interactive: they are a digital snapshot. Often, these maps are from paper sources. Even if you zoom in on such a map snapshot, you have not changed the image as it was originally scanned.

The second kind of map is one that you generate interactively, like those found on MapQuest or in the American FactFinder. In this kind of map, you are building the map you want online, adding and subtracting layers, by interacting with the site.

When you use any of these maps in your work, you must cite the source - just as you would cite the source of a journal article. If you are using a map in a paper, you must cite the map both in a caption under the map and in a reference list at the end of the paper. What follows are specific directions for creating these citations. Because URLs can be unwieldy to text editing systems, it is permissible to left justify all lines of a citation, instead of indenting as in print.


Map Snapshots: Static Digital Map



Map 2. "Delaware, Ohio." 1885. Sanborn Fire Insurance Maps, 1867-1970 - Ohio.

Author if known. Map Title [map]. Date of map creation if known. Scale. "Title of the Complete Document or Site". Date posted if known. Computer Database Title. <URL> (date accessed).

Delaware, Ohio [map]. 1885. Scale not given. "Sanborn Fire Insurance Maps, 1867-1970 – Ohio". OhioLINK Digital Media Center. < image=Bdg/SanMaps/reel28/6674/00001.sid&oid=Reel28-6674-00001& sessionID=2108467497&title=Delaware%2C+Ohio&date=February%2C+1885& format=list&results=20&sort=thedate&searchstatus=1&hits=136&count=1> (2 May 2005).


Map Generators and Browsers: Interactive Reference and Thematic Maps

These maps require a slightly different citation format in that the name of the mapping service must be identified as well as the name of the person generating the map.


Interactive Reference Map


Map 3. "Delaware, Ohio", Inc.

Author or statement of responsibility. Map Title [map]. Data date if known. Scale; Name of person who generated map; Name of software used to generate the map or "Title of the Complete Document or Site". <URL> (date generated).

Delaware, Ohio [map]. 2001. Scale undetermined; generated by Deb Peoples; using ", Inc". <> (2 May 2005).


Interactive Thematic Map


Map 4. "Merced, California, 1990 Household Size". U.S. Census Bureau

Author or statement of responsibility. Map Title [map]. Data date if known. Scale; Name of person who generated map; Name of software used to generate the map or "Title of the Complete Document or Site". <URL> (date generated).

U.S. Census Bureau. Merced, California, 1990 Household Size [map]. 1990. 1:91,302; generated by Deb Peoples; using 1998 TIGER/Line. <> (7 Feb. 2002).


Real Time Maps and Images

Real time maps and images differ from map generators and browsers in that they consist of continuously updated images or maps usually focused on a particular topic or site. These are, in essence, "live maps."
