Every search strategy must consider three things:
•Where to search.
•How often to search.
•Which search terms will best help me find the information I need?
Use Citavi to search in:
•Library catalogs for books you can lend from your institution's library or request through interlibrary loan.
•Bookseller catalogs for books you can purchase.
•Databases for journal articles, gray literature, contributions in edited books, and books.
•Specialty search engines (for example, Scirus) for journal articles.
Keep in mind that different resources are updated more or less frequently. A library catalog may changes less frequently than a specialty search engine, so repeat your searches accordingly.
