Internet Newsletter for Lawyers
Often considered to be the industry leader in information provision, the company originated in Dayton, Ohio in the mid 1960s where it operated as a contractor to the US Air Force. Until 1979 the company was known as a supplier of legal information. It has been said that the system they introduced in 1973 revolutionised the way in which legal research and analysis was carried out. In 1979 Nexis the companion news and business information service was introduced. In 1994 Reed Elsevier acquired LexisNexis. The company has continued to develop and grow and is recognised as an international player with established and expanding operations around the world.
LexisNexis Professional, one of the LexisNexis products, is often considered to be the largest business database in the world. It is a powerful online research tool offering a wealth of news, company, legal, market research and directory sources. It contains information from 36,000 sources, holds approximately 3.7 billion documents and has an archive going back in some cases, 33 years.
It is an expensive product and its pricing structure is tiered according to the level of access. An organisation chooses what sources they will subscribe to within pre-defined groupings. As well as offering a flat rate fee payment option LexisNexis also offer a pay-as-you-go system whereby one only pays for the amount of time used on the system. A combination of both a flat-rate fee and a pay-as-you-go service is also offered. What this means is that one can opt to pay a flat rate fee for accessing a particular group of sources as well as having a pay as you go option for accessing other, less frequently used sources. For frequently used sources, a flat rate fee is recommended.
It is possible to change the layout of this screen by choosing the Preferences link in the top right hand corner of the blue navigation bar. Due to the large size of the database it is not suitable for browsing. It is important, therefore, to have some understanding of the database itself and the basics of how to carry out a search. LexisNexis are providing free training sessions to subscribers and this is a very worthwhile service to avail of, particularly if your subscription is a pay-as-you-go subscription.
The help option explains how to use Lexis Nexis and will certainly provide a user with enough information to enable them to carry out a search and to navigate around the database. The Need Help button also gives specific help on carrying out a search. In addition, it is possible to click on any of the help icons (the little red question marks) to access help related to a specific function. These are helpful and are context specific to that feature although personally I prefer a help function that is completely context specific. In other words it is possible to click on help at any time and the help provided relates directly to the task being undertaken.
The information icon (the little "i" icon) provides information about the source that is currently selected but at this level it is not possible to access information about the other sources that make up a subscription. It is necessary to drill down through the source hierarchy in order to do so. Again I would prefer to be able to view what sources are included in the subscription with an overview of their content and structure at this top level.
Use the Browse Search Directory button to drill down the hierarchy of sources until the lowest level is reached and it is possible to select the source for searching. The "information" icon appears beside a source name when it reaches this level. Clicking on this provides information about the source chosen. When this level is reached it is possible to select the source for immediate searching by clicking on the OK button. Alternatively the source can be saved for future use by clicking on the Save button. It will then appear in the list of saved sources. It is a good idea to save frequently used sources in this list.
When a source has been successfully selected, enter the search terms in the Search Terms box.
LexisNexis supports Boolean searching. Click on the help icon beside this box to get a list of the Boolean connectors supported. The main ones include AND, OR, AND NOT, W/x. The W/x connector specifies within how many words of the first search term the second search term must appear, for example: "conflict W/2 law".
Truncation and wildcards are also supported to allow for more powerful searching. The exclamation mark ! is used to truncate words. It finds variations of words from a root (e.g., negligen! will find negligent, negligence or negligently). The asterisk * is used to replace a letter in a word (e.g., wom*n). It also supports the use of parentheses to help define the logical order in which a complex search is carried out.
(delay and lenienc!) and (dpp or Director Public Prosecution)
Notice that "of" is omitted from the phrase "Director of Public Prosecutions". LexisNexis doesn't recognise words such as of, to where, by. It also finds regular plurals such as s, es, ies.
There are good options for narrowing a search. When a list of results is obtained there is an option to search within the set of results in order to produce a more precise list of results. LexisNexis allows what is called Segment searching. What this means is that a particular section or field of the document is searched. This varies according to the source being used. For example a search within the Irish Reported and Unreported cases would allow searching by Counsel, Court, citation and other terms specific to searching case law. Using this option also helps with the formatting of your search by automatically inserting brackets into the search string. It is also possible to restrict the search by date and a useful feature is that searches can be saved and re-run whenever required.
All of the above has described searching from the Power Search screen. There are also options to carry out a Quick Search. The categories of sources are displayed on the left of the screen (see the picture). The sources available reflect the subscription level. The Quick Search option displays screens that are laid out to reflect the type of resource being searched. Thus a case law search will display fields requiring the case name information entered or the name of the court to be entered. A Quick Search of Journals on the other hand would require the title or author to be entered. Overall the Power Search allows for more defined and precise searching whereas the Quick Search is precisely for carrying out a shorter more defined piece of searching.
Searching is not as user-friendly or as intuitive as some other databases. A certain level of training is required not only to understand the search process but also to understand the structure and content of the database. However, once a certain level of confidence and expertise is obtained, an enormous body of material lies waiting to be discovered and all at the user's fingertips.
