For general reference it’s fine. It is a good starting place for figuring out what you want to learn more about or just a basic “what was this event?” Personally I’ve found it is not reliable for depth. A lot of the times I’ve tried to check a source, it has not checked out. Like it may be a cite to a chapter of a biology textbook and when you look up the table of contents, it’s a completely different topic than the citation. Plus things that should be cited are not cited. Like I said, it’s a starting point but not an ending point.

Great for summaries, poor for in-depth research.

Fantastic for finding sources by digging around in the citations section.
