Introduction to the LEXIS-NEXIS ServicesforSchools of Library & Information Science

Prepared by: Carol S. Johnson

LEXIS-NEXIS Academic & Library Services

Manager, Library & Information Science Education

learn using news sources
Can use same search logic across services

News sources easy to understand

Make searching interesting and fun

Three News libraries

NEWS: all news sources

REGNWS: regional news, newspapers

TOPNWS: last two weeks news

Learn Using News Sources
using traditional lexis nexis
Client software

“Classic” interface

Underlying organization and structure for all interfaces

Aids in understanding why and how of L-N functionality, and some of the “quirks”

Using Traditional LEXIS-NEXIS
organization of services
Services structured by organizing databases into LIBRARIES and FILES

Same structure beneath all platforms

LIBRARY

FILE

DOCUMENT

WORDS

Organization of Services
organization of services5
A LIBRARY is a group of related information

A LIBRARY may contain information

of a certain TYPE,

on a specific TOPIC ,

or for a specific GEOGRAPHIC region

Organization of Services
libraries by type
NEWS Library:

Newspapers

Magazines

Wire Services

Broadcast transcripts

Newsletters

REGNWS Library: Regional News

TOPNWS Library: Recent News (2 weeks)

Libraries by TYPE
libraries by topic
Differenttypes on same topic

GENFED - Federal Case Law, Statutes

COMPNY -- Company information

ENVIRN -- Environmental information

SPORTS -- Sports news, publications, bios

Libraries by TOPIC
libraries by geographic area
Different types of info from same region:

North and South America

Dutch

German

Asia Pacific

Some contain non-English language sources

Libraries by GEOGRAPHIC Area
what s in a library
Each LIBRARY contains FILES

TWO types of FILES:

INDIVIDUAL FILE

Documents from a single publication, i.e The New York Times is in the NYT file

Materials from one publisher, ex. ABCNEW file contains transcripts from many ABC News shows, including World News Tonight with Peter Jennings, 20/20, Good Morning America

What’s in a LIBRARY?
what s in a library10
GROUP FILE has multiple sources

Large group files: lots of sources

all full-text sources are in ALLNWS file

all newspapers are in the PAPERS file

Small group file: small number of sources

Indiana newspapers in INNWS file

What’s in a LIBRARY?
organization of services11
FILES contain DOCUMENTS

The text from the source

DOCUMENTS may also be referred to as:

ARTICLES

STORIES

CASES

Nomenclature varies by source

We’ll use DOCUMENTS for consistency

Organization of Services
organization of services12
DOCUMENTS consist of WORDS, may be:

Alpha: texas or san antonio

Numeric: 99.44 or 2000

Alpha-numeric: 401K or Y2K

In the LEXIS-NEXIS services, a WORD is any group of characters with a space on either side

Organization of Services
choosing a library and file
Look for area of interest, you may need to use more than ONE library or file

Choose smallest FILE that will give desired results: DON’T search ALLNWS (all news), when you only want a New York Times (NYT) article

In most LIBRARIES, you can combine FILES, separating with commas, for a custom search

Choosing a LIBRARY and FILE
search options
Boolean, using TERMS & CONNECTORS

Essentially the same as other Boolean searching but language, operators and functionality are different in LEXIS-NEXIS

FREESTYLE ™ feature; plain language searching (natural language)

GUIDED FORM: LEXIS-NEXIS Academic Universe, LEXIS-NEXIS Universe, based on underlying Boolean search

Search Options
search options15
Research Software 7.1.2

Customizable tool bars

Gives options for Searching and Viewing in “Classic” or “Graphical” mode

My favorite:

Search Classic

View Graphical

Search Options
unique searching capabilities
When using LEXIS-NEXIS, user is searching FULL TEXT of documents, not indexes or abstracts

Can restrict search to specific portion (called SEGMENT) if user wishes

Use same search logic through services, even with different interfaces

Unique Searching Capabilities
boolean searching
Original LEXIS-NEXIS search logic

Still used most by many customers

Allows precision searching

Favorite of most information professionals, librarians and researchers

This is what every librarian and future librarian should learn first!

Boolean Searching
boolean search basics
Select an appropriate LIBRARY

Choose an appropriate FILE

Select the smallest FILE that will give the results you need

Enter a SEARCH composed of WORDS

Don’t be intimidated by LIBRARY/FILE acronyms; type number to the right of Library or FILE name to see description

Boolean Search Basics
boolean search basics19
Choose appropriate search words to define what you’re looking for

Simplify the search words

Connect the search words

Restrict your search results to a particular time frame (date restriction)

Confine your search to a part of a document (segment searching: segment = field)

Boolean Search Basics
what s a word
A group of characters with a space on either side; may be alpha or numeric; i.e. _XXX_

Most punctuation is recognized as a space, i.e. John D. Rockefeller, 401-K

An exception is the “embedded period”

(a period not having a space on either side, which is viewed as a character)

i.e. A.J. Foyt, 99.44

What’s a WORD?
words to avoid
NOISE WORDS: so called because they are so common inclusion adds no value

Personal pronouns (he, she, they)

Most forms of the verb “to be” (be, is, was)

Some conjunctions (and, as, because)

RESERVED WORDS:

words used as part of search logic (and, or) or

to identify features (lexsee, autocite)

Words to Avoid
choose search words
Make a list of words that describe topic of interest

Include alternatives (synonyms, antonyms)

Avoid words that are too general

Think as if you were writing the document; what words would you include

Adjacent words are treated as a phrase

Choose Search Words
plurals possessives
Automatically searches for plural and possessive forms of most regular words, i.e. if word is made plural by adding s or es or changing final letter y to ies; for example: boy finds boys, boy’s, boys’

Does not search for irregular plurals; i.e. if word ends in us or is or other irregular plural form; child does not find children

Plurals & Possessives
compound words
Compound words using a hyphen are sometimes treated as a single word, but not always

Be safe: enter both variations, i.e. anti-trust and antitrust

Authors aren’t necessarily consistent!

Compound Words
simplify search words
Universal characters let you include all variations of a word without entering each

*holds a space for one character; may be used in middle or at end of a word; wom*n finds woman, women, woman’s and women’s

! may be used only at the end of a word root to find that root plus all variations; recycl! finds recycle, recycling, recyclable, etc..

Simplify Search Words
join words connectors
OR - finds either or both search terms; used for synonyms, antonyms or alternative expressions

g.m. or gm or general motors

bush or gore

stock or share or equity

Join Words: CONNECTORS
join words connectors27
W/n - proximity connector; finds documents with words that are within some number (n) of each other (does not work across segments)

bush w/10 cocaine

Tip: ALWAYS use betweenfirst and last name, george w/2 bush; bill w/2 clinton

Join Words: CONNECTORS
join words connectors28
AND - both search terms in each document

clinton and gore

general motors and market share

Order of operation:

OR

W/n (Remember n = number; n = 1-255)

AND

Join Words: CONNECTORS
date searching
On a date:date is

Spell out the word isor

use the arithmetic operator =

date is 2000

date = January 15, 2000

date = 1/2000

NOTE: System assumes two-digit years are within past 100 years

Date Searching
date searching30
After a date:date aft

Abbreviate out the word aftor

use the arithmetic operator > (greater than)

date aft 1999

date > Aug. 19, 1999

date > 10/99

NOTE: Month names and numbers are equivalents; use the American convention

Date Searching
date searching31
Before a date:date bef

Abbreviate out the word befor

use the arithmetic operator < (less than)

date aft 1999

date > August 19, 1999

date > 8-99

NOTE: Systems recognizes either dash or slash

Date Searching
date searching32
Combine operators to search between two dates

date aft AND date bef or

date > and date <

Date aft 1993 and date bef Sept. 1995

NOTE: Aft 6/30/99 does not include that date; aft 2000 would get nothing now!

Date Searching
special operators
Parentheses ( ): use to assure that system groups words separated by a connector

For example: (channel w/2 tunnel) or chunnel or (ken! w/2 starr) or (bill w/2 clinton)

Quotation marks “ ”: use to search reserved words when reserved word is first or only word in the search

For example: “lexsee”
