Searching for gray literature in databases
The NDSU Libraries subscribes to many subscription databases. Increasingly, databases, particularly those of a technical nature, are beginning to index gray literature. When using databases to find gray literature, the search options available on the advanced search screen are frequently helpful. Usually you will find a field that allows you to narrow your search to technical reports or conference proceedings. Using these options will make your search much easier. Since databases are always evolving and adding new materials it is a good idea to check back with the ones you use most frequently to see if they have added gray literature.
