Library Express Source Directory
The Sources Tab in LexisNexis Library Express is an important resource if you're looking to instantly narrow your search results. You can search for specific sources or search for sources by a particular topic. This is extremely useful if you're new to research and don't know where to start.
 Finding a Specific Source
The way to find a specific source is to search for it in the Keyword Box of the Find Sources form. If you're searching for the "New York Times", simply type "New York Times" into the Keyword box and click the red "Find Sources" button.
The results set will then appear. Click on the small box next to the source (indicated by the blue arrow on the left side) and then click the red "OK-CONTINUE" button (indicated by the blue arrow on the right side) to search within that particular source.
From there, you will go to the PowerSearch form where you can add different index terms or search within different document sections, just like normal.
 Finding a Source By Geographic Location
On the Browse Sources tab, in the #2 section, you will see the "Filter By Country" drop-down box. If you would like to see all the sources coming out of one country, select the country and click the red "OK-Continue" button to see the results set.
If you would like to see the sources in the United States, click "United States" in the country drop-down box and another box will appear. From there, you can pick sources by region or state. This is particularly useful when you are looking for hometown newspapers. You can also search all news publications from one state. Each state has an aggregated source with all of the news publications. If you wanted to search New York, look for the source called "New York News Sources" in your results list.
 Finding a Source by Topic
On the Browse Sources tab, in the #1 section, you can pick whether you would like to search by publication type, news and business topics, industry, or area of law. Depending on the button you click, the yellow folders at #3 will change accordingly. The same can be accomplished in the #2 section. You will see the "Filter By Topics" drop-down box. Click there to see a list of News and Business Topics, Industries, and Areas of Law. This list and the folders from #1 contain the same topics.
On the Find Sources tab, you will find a similar set of options, but in boxes that will let you pick multiple topics at once. You can also find sources by Region of Coverage, Publication Language, and Frequency of Update here.
 Use Group Files to Select All
As you browse through the source directory, you will often come up with a whole class of sources that you want to search. Unfortunately, there is no "Select All" feature in the source directory. However, LexisNexis has created group files that correspond to many of the source categories.
The most popular group files are highlighted in this wiki; see the Library Express Links Category page.
To find out if there is a group file for the class of sources that interests you follow these steps, in the steps below:
- 1. Browse to the group of sources that you want; in the example, we have selected the "Industry" radio button then browsed down to the Engineering folder.
- 2. Change the "Multiple/Single Source" dropdown to "Multiple-source Files." This will show all the group sources in this folder
- 3. If there is a group source covering all or most of the single sources in the folder, it will usually have a name ending in "stories," for example "Manufacturing and Engineering Stories." Use the "i" source information icon to see details of what is covered. Select this source and run your search.
