Why Reference Works?
Scholarly reference works are useful for the following:
- An overview of a topic
- Topic ideas for a paper topic or narrowing your topic
- Finding keywords for searches
- Bibliographies for further research
Reference works are good starting points for research, but are rarely cited in research as secondary sources.
