A Citation Map is a graphical representation that shows the citation relationships (cited references and citing articles) between a paper and other papers using various visualization tools and techniques. A paper can be an article, proceedings paper, book, or other document type as defined by the product database that you are using.
Using citation mapping, you can analyze which researchers are citing your papers. You can also choose to organize and color code the results by author, year, journal title, subject category, and more.
You can also set up a graphical representation of the papers that you have cited in a published work. You can then choose to organize and color code the results by author, year, journal title, subject category, and more.
Creating a Citation Map
From a Full Record page, click the Citation Map link to go to the Citation Map start page where you can begin to create your Citation Map.
1. Select a direction.
2. Select a generation.
3. Click the Create button to create your Citation Map.
The Target Record
After you create your Citation Map, the target record is shown in the middle of the Citation Map panel. To the right of the target record are papers that cite the original paper (citing articles). This is the forward view. To the left of the target record are papers that are cited by the target record (cited references). This is the backward view.

Citation Map Panels
The Citation Map is generated and displayed in a three-panel window.
View of Citation Map, Results Set, and Record View Panels
Navigating the Panels
You can move the nodes around (including the target node) by clicking and dragging them using your left mouse key. This feature allows you to see parts of the map that are on the edge of the panel. This dragging action also brings the centered-map section into view so you can see the individual nodes more clearly.
By hovering your cursor on any node, you can view bibliographic information about that paper such as article title, source title, author, and much more. If your subscription includes the Chinese Science Citation Database, then some bibliographic data may display in both English and Chinese.
Be aware that if there is no article title, the system will display an "article title not available" message. You will see this message mostly for cited references in which the record is not indexed in any of our citation indexes such as Web of Science.
A white expand / collapse button displays in the bottom-right corner of the target node if there are citations for that record. Click to expand or collapse the display. You can also find these buttons on the back and fwd nodes.
Results Set and Record View Panels
The lower portion of the Citation Map window contains a Results Set panel (lower left) and a Record View panel (lower right).
A close control icon above the Results Set panel allows you to close the Results Set and Record View panels and view the Citation Map in full screen mode.
An open control icon allows you to reopen the Results Set and Record View panels and view record data.
Results Set Panel
The Results Set panel contains all of the records covered by the Citation Map you are currently viewing. The target record will have a yellow background to set it apart from the other records in the table.
The check box for the target record is always selected when the Citation Map initially displays.
Click the check box of a record to select one or more nodes in the Citation Map. A red border appears around each selected node in the Citation Map. Choose Set Node Color from the Appearance menu to change the color of each selected node in the Citation Map.
The Select All check box in the column header allows you to select all records in the panel.
Use the standard page navigation arrows to move from page to page in the panel.
Use the standard Display menu to choose to display 10, 20, 50, or 100 records in the panel.
Primary Author Field
This box displays the primary author of the article (the first listed author of the article). Click the Primary Author link to sort the list of records alphabetically by author name from A to Z or click again to sort the names from Z to A. If there is no primary author, then the system the name of the group author. If no group author, the system display double-hyphens (--).
Journal Name Field
This box displays the full source name. If there is no full source name, then the system displays an abbreviated journal name. You will see the abbreviated name mostly for cited references in which the record in not indexed in any of our citation indexes such as Web of Science.
Article Title Field
This box displays the full article title. Click the Article Tile link to sort the list of records alphabetically by article title from A to Z or click again to sort the titles from Z to A. If there is no article title, the system will display an "article title not available" message. You will see this message mostly for cited references in which the record is not indexed in any of our citation indexes such as Web of Science.
Record View Panel
The Record View panel displays field data for source records in the product database. The Number / Title of a record is linked to the Full Record if the record is in the product database.
By selecting and double-clicking any node in the Citation Map, you can view Full Record details about that record in the Record View panel.
Note the following:
If your subscription includes the Chinese Science Citation Database, then some bibliographic data may display in both English and Chinese.
The Manage menu allows you to create a new Citation Map and to save a Citation Map as an editable image.
Create New Citation Map
This options allows you to create a new Citation Map for a selected node that appears on the citation tree and in the Results Set panel.
Save Citation Map As Image
This option allows you to save your Citation Map as an independent image. The default format for saving the image file is PNG (Portable Network Graphics).
After you select this option, you can open the image or save the image to a folder on your computer. During this process, you can change the file format to another format such as GIF or BMP by replacing the PNG file extension after the file name.
If you have a graphics tool (for example, Macromedia Fireworks), you can modify your graphics image. For example, you can add text, notes, or resize your image.

The Edit option allows you to change the direction of your Citation Map and the number of generations that appear. When you select Edit, the Citation Map start page appears for the current target record.
The Appearance menu allows you to order, color-code, and label citation tree nodes according to various record fields.
Order Nodes By
This option allows you to select a field by which to sort the nodes. Each node in a node grouping is sorted by the selected field alphabetically / numerically.
For example, by selecting Publish Year from the Order Nodes By menu, you can group records that were published in the same year.
Color Nodes By Menu
Color Code By
This option allows you to assign colors to nodes according to their record properties. That is, you can select a field to which to apply colors. This process takes the top 20 occurring data values and assigns them one of the 20 node colors (see Set Node Color for more information). Any node that is not within the top 20 values remains black.
For example, by selecting Publish Year from the Color Code By menu, you can view, by color, records that were all published in the same year.
Color Code By Menu
Set Node Color
This option allows you to apply color to selected nodes on the Citation Map.
Set Node Color Palette
Did You Know ... If you decide to color the nodes by Publish Year (or another option), you may get a different view - the selected Color Code By field takes precedence.
Set Node Text
This option allows you to select the field information that you wish to display in the nodes in the Citation Map.
For example, by selecting Author from the Set Node Text menu, you can view the author's name in each node.
Set Node Text Menu
The Print button opens a pop-up browser window that displays the Citation Map image. Click the Print link in the top right corner to print the image.
After you create a Citation Map, use the Year Range feature to set upper and lower year ranges. Drag and release the left and right arrows to adjust the year range. For example, you can set the year range to view records published from 1995 to 2005.
Click the Limit button to redraw the Citation Map to show only those records that fall within the selected year range. After you redraw the map, the Results Set panel will list only those records shown in the redrawn Citation Map including the target record. The Record View panel continues to show the target record.
Note that you cannot adjust the year range beyond the date of the target record.
Quick Change Buttons
These buttons help you quickly reconfigure your Citation Map.

About Citing and Cited Records
Keep in mind the following when analyzing citations.
Forward Only citations (citing articles) come from source records in the product.
Backward Only citations (cited references) come from source records and non-source cited articles.
For more information, see Times Cited Count.
More About Generations
A paper's cited references and citing articles are referred to as the first generation of cited and citing papers. Each of those cited papers may have cited references of their own and each of the citing articles may have citing articles of its own. This second level of papers is referred to as the second generation.
Please be aware ... Nodes in a Backward Only, second generation Citation Map end at the first generation if they are not source records in the product or if they are inaccurate variations on a source record.
Please note ... Nodes in a Forward Only, second generation Citation Map end at the first generation if those records do not have citing articles.
When trying to print a Citation Map with a large number of citations (forward, backward, or both), we suggest:
You may encounter performance problems if you try to create a Citation Map for a record that has a large number of cited references and citing articles. This may be particularly true if you select the Second Generation option in both the Forward and Backward direction. If you encounter performance problems, we suggest that you revise your search and select only the Forward or Backward direction, but not both.
