How do I document my search for grey literature?
You may also need to record grey literature searching and results in a different way, and separately from other database searching.
Searching multiple source formats and platforms or employing alternative methods of data collection (e.g. correspondence with experts) means it will not be possible to replicate the same kind of search strategy you would use for mainstream sources.
You will also need to consider how you will record the information you find, as not all grey literature sources may be able to be integrated with referencing software.
