Q. How do I cite MLA?

Purdue OWL's MLA Formatting & Style guide provides instructions on both of these.  According to Purdue OWL, the basic book format should be:

Last Name, First Name. Title of Book. City of Publication, Publisher, Publication Date.

According to Purdue OWL, the format for electronic sources including databases should be:

Author. "Title." Title of container (self contained if book), Other contributors (translators or editors), Version (edition), Number (vol. and/or no.), Publisher, Publication Date, Location (pages, paragraphs and/or URL, DOI or permalink). 2^nd container’s title, Other contributors, Version, Number, Publisher, Publication date, Location, Date of Access (if applicable).
