Final answer:
The three major finding tools are web search engines, books & journals, and library discovery tools/indexes. Web search engines may miss subscription-based scholarly resources and may be hard to focus your search. Library discovery tools/indexes may not include full-text and can be hard to focus your search.
Step-by-step explanation:
The three major finding tools are web search engines, books & journals, and library discovery tools/indexes. Each of these tools has its weaknesses:
- Web search engines: Misses most subscription-based scholarly resources. They may not include full-text and may be hard to focus your search.
- Books & journals: Not a finding tool, as defined in Chapter 1.
- Library discovery tools/indexes: May not include full-text and can be hard to focus your search.
