Two Stages of Information Searching
Find It!Identifying specific books, articles, reports on a given topic

With technology, these separate tasks are blurring together

Invisible Web: What It Is…Joe Barker, University of California, Berkeley Libraries
Periodical Databases
Examples - Biosis Previews, CompendexWeb
Created by humans, usually subject experts
Index a defined discipline and a finite set of published resources (mainly journals, but may include books, conference proceedings, etc.)
Both the databases and the materials indexed cost money
Article Databases page on InfoDome
Fulltext Journal Collections
Examples - Elsevier ScienceDirect, JSTOR
Pay per view or subscription
Created by humans, sometimes OCR
Collections usually based on a publisher’s offerings
Searching is very deep, but restricted to a “narrow” viewpoint
Data Collections
Examples - GenBank, PDB
Raw data
Created by experts, sharing their results
Usually run by government entities
Generally free
Hybrids
Examples - Scirus, EntrezMixes of fulltext, web documents, and/or raw dataMix of free and fee materialsTwo different approaches
Single database with multiple resource typesSingle search interface that searches multiple databases
Methods of Searching
Follow the citations (“Breadcrumbs”)
Subject searching in a database or two or three…
Cited reference searching
Ask an expert
Follow that Trail!
Start with one or few known articles, etc.
Track down the material in their bibliographies
And continue the process from article to article
Database Searching
Searching by topic, author, species, etc. in one or more databasesGeneral Search Techniques
Be specific, especially if searching in a fulltext databaseBoolean logic
• Boolean Searching on the Internet, Laura Cohen, Univ at Albany Libraries
Phrase or adjacency searching
Database Searching
TruncationEcolog* retrieves ecology, ecologies, ecological
No standard symbol
Field searching
LimitsLanguage, gender, format, etc.

Cited Reference Searching
Examples - Web of Science, Highwire Press
Trace research forward in time from a specific reference
Very powerful tool, but somewhat limited by human mistakes
Get It!
Many databases provide links to the online versions of the journals
OpenURL standard
If database doesn’t have linksThe PAC
