- Name of the databases you searched.
- Date of the search. (Make sure this is recent.)
- Time period covered by the search.
- Detailed search strategy.
Tips:
In most databases you can set up an account and save your search history. This is useful while you are creating your search and for documentation afterwards.
You can handle time period coverage in two ways. If you search using a date limit, that's the time period of your search. If you search without a date limit, check the database documentation to find out the date coverage of that database.
