MoM is a preferable source of mineral information.
The bookstore has again denied that this has happened, but if you present the receipt to Margaret Parks, she'll correct the mistake. Otherwise, begin researching the mineral with an eye on creating an annotated bibliography. I thought there was something not quite right with my grade spreadsheet, but I couldn't find the error. I apologize profusely for the error. It can take a week or so to receive materials from other libraries.
