WorldCat (OCLC)
by Laura Young What Is WorldCat?
WorldCat includes items in almost any format from thousands of libraries around the world. Items included date as far back as 1000BC. Strengths:
- Large database containing millions of records
- Includes records in approximately 400 languages
- Search pages are user friendly
Weaknesses:
- Some searches such as the “title phrase” search, aren’t always accurate
- The Advanced and Expert searches are very similar and could be combined into one page
Features:
- Keeps track of previous searches
- Allows the user to email records
- Records link the user to libraries in their area
Basic Search The basic search page allows you to search by keyword, author, title, ISBN and year. Basic Search Example:
I’m looking for new works by David Sedaris.
Step 1:
In the "author" field, type "Sedaris, David".
Step 2:
In the "year" field, type "2004".
Step 3:
Click on the “search” button. 
Advanced Search
The advanced search allows you to search in more detail or add limits to your search. You can search by categories such as publisher, accession number, or series title. You can limit your search by language, format, rank or a particular library. (cont.) Advanced Search Example:
I know David Sedaris lives in France. Are any of his books available in French?
