One way to reference MIMS, AMH, eTG, AccessPharamcy or Nursing Consult, is to treat it like an electronic reference resource.
The reference will have the following elements:
If the reference topic has no author, use the topic as the first element in the reference. Author information may be listed on the first page of the entry or under a section called 'Contributors' (or similar).
Include the year of the last update in brackets. If there is no update year listed, use the copyright year. This information may be included at the top or bottom of the screen.
Include the word 'In' followed by the title of the resource in italics (e.g. MIMS Online, etc).
Include the basic access URL after "Retrieved from". No access date is required for electronic reference entries.
