Student or Learner
I would like to cite from this book but I am not sure the correct format for this one, I think some information is missing. Like the country/university.
Pearson - Ekwall/Shanker Reading Inventory, 6/E - James L. Shanker & Ward Cockrum
I have been able to get this citation:
Shanker, James L. and Cockrum, Ward (2013) Ekwall/ Shanker Reading Inventory. Pearson.
It should tell you on the inside page where it was published. Pearson is a huge British company based in London, but its books are published in many countries. If the book really doesn't give anything, then I would use London.
Which system are you using? Is the university really necessary?
Also, shouldn't it have the edition number?
