This website presents a collection of topics that are useful to know when studying crystallography, or when thinking about it more deeply. It is written to be accessible to complete beginners, but it may also be useful for those who have taken a crystallography course but feel they never quite understood it well, or who have been working in the field for years but would like to strengthen their more advanced knowledge.
The pages on this site are still a work in progress. While the content may not be complete, any errors in the text are unintentional. If you notice any mistakes, please feel free to contact me by email.
Note that the space-group-related data is extensive and has been compiled on a separate page.
