In authoritative order:
Primary sources
- Artist websites & press releases
- Record company websites
- Discogs: As far it concerns information taken from the physical release
- Muziekarchief: Also based on physical copies, so quite reliable. However, regularly contains typos and other careless work so try to double check the data elsewhere.
Secondary sources: specialized sources
- Written: Autobiographies, biographies, discographies
- Online: Thoroughly researched fan websites
Secondary sources: generalist sources
- Discogs: Information not taken from the physical release, for example the release date. To find the source Discogs used, go to the link "Show History/Edit" on the right hand side of the screen.
