Anotations

Scope note:

Reference works setting out formulas, recipes, or prescribed forms or models. In pharmacological contexts, use for non-standard works formulating the ingredients and amounts to be used in preparations, but not including recommendations for such things as use and dosage. For reference works detailing preparation of drugs and medicines, including their use and dosage, especially those works recognized as official or standard sources, use "pharmacopoeias."
