LexisNexis Academic does not display durable links for each document. The URL displayed in the browser address window is not stable and should not be stored as a link. However, it is relatively easy to make a durable URL (also known as Persistent URL or PURL), and many popular links have been created by LexisNexis staff ready for your use.
==Before You Start==The URL API allows users to build several types of URLs that are suitable for use in course syllabi, assignments, research guides, and bookmarks.
*Article-level durable links to specific full-text documents*Source-level durable links to search within specific LexisNexis sources*URLs that function as saved searches
===User Authentication===See the article About Subscription Links for user authentication issues.
===Shortcut: Lists of Links===Instead of building your own links, you may be able to simply copy the link you want from one of these sources. *See [[:Category:Academic Links|Academic Links]] for pages on this wiki that include lists of links.*Our A-Z list contains stable title-level URLs for all of our single sources.

===Direct Link To Search Any Source===See the article on Finding a Source CSI
==Examples==For more examples and complete descriptions of these types of links, please download and read the URL API Specification provided above. ===Document-Level Links===Run a search that retrieves a specific document.<br/>====News and Periodical Documents====The link must use the constant source identifier (CSI) for the particular publication.'''Example:''' Link to an article in Chronicle of Higher Education <br/>http://www.lexisnexis.com/hottopics/lnacademic/?verb=sr&csi=171267&sr=BYLINE(Lila+w/3+Guterman)+AND+HLEAD(Journal+Eases+AND+Policy)+AND+DATE+IS+June+28+2002
====Legal Cases====All links to U.S. Federal and State legal cases can use the constant source identifier (CSI) for the U.S. and State Cases combined source. The CSI is 6496. Use the "CITE" segment to search for the legal citation in standard legal citation format. '''Example:''' Link to U.S. Supreme Court decision Brown v. Board of Education<br/>[http://www.lexisnexis.com/hottopics/lnacademic/?verb=sr&csi=6496&sr=CITE(347+U.S.+483) http://www.lexisnexis.com/hottopics/lnacademic/?verb=sr&csi=6496&sr=CITE(347 U.S. 483)]
===Source-Level Link===Also called "title-level links." Opens the Power Search form, with the specified source already selected and ready to search.<br/>'''Example:''' Search within the New York Times <br/>http://www.lexisnexis.com/hottopics/lnacademic/?verb=sr&csi=6742
Note: The LexisNexis A-Z Title list on the [http://www.amdev.net/rpt_std_content.php Subscriber Tools] site includes links to all individual titles. You can create a link for any source (including group sources which are not included in the A-Z Title List). All you need is the CSI (Constant Source Identifier) to add after the "csi=" part of the URL. In the New York Times example above, the CSI is 6742.
You can use the Source Directory to get CSIs. See the article on Finding a Source CSI
===Table of Contents Links===LexisNexis has created an advanced Table of Content (TOC) search form for legal materials that supports both browsing and searching. TOC view is available for 200+ sources, including the United States Code and all state codes.<br/>'''Example:''' Link to TOC view of the United States Code<br/>http://www.lexisnexis.com/hottopics/lnacademic/?verb=toc&csi=6362
Note: As with the Source-Level links, there is no need to construct your own TOC links. A list of all TOC links is available at [http://www.amdev.net/rpt_std_content.php Subscriber Tools]

==Frequently Asked Questions== What’s an “API”?The acronym stands for “application programming interface.” It’s a mechanism that allows programmers to call functions within another application. In this case, you will be constructing a URL rather than writing a computer program. The application you will send instructions to is the LexisNexis Academic service itself, and you will be able to call the following three functions.
<ul><li>Document-level link – retrieves a specific document.</li><li>Source-level link – opens the Power Search form and populates the source selection options to facilitate user-initiated searching of a specific source.</li><li>Academic URLs for Search Forms– open any search form in LexisNexis Academic.</li></ul>The URL API is also used to support third-party vendors who provide article linking and federated search software to academic libraries. The developers of these systems can use the API to link authorized user automatically to full text documents in the LexisNexis Academic service. In the case of link resolvers, the required document is identified from a citation in a source database and, once LexisNexis Academic is identified as an appropriate target database, the API is used to deliver the full text document. Federated search services can use the API in a similar way, to link from a citation in their results list to the full-text document in LexisNexis Academic.
Do I Have To Install Anything?No. The URL API Specification simply provides directions for constructing URLs. The API does all the work of interpreting these URLs within LexisNexis Academic. When Will My Link Resolver Work with LexisNexis Academic?That depends on whether the company or in-house team that provides your link resolver has incorporated the LexisNexis A-Z Title List and the URL API into its service. LexisNexis is currently working with the following companies and organizations to support their link resolver systems. If your provider is not on this list, please direct them to this webpage to obtain the Specification and LexisNexis contact information.<ul><li>CSA</li><li>Ex Libris/SFX</li><li>OCLC Openly Informatics</li><li>OhioLINK</li><li>Serials Solutions</li><li>TDNet</li></ul>
