From the MLA website:
My impression is that this means that "medium of publication" needs to be a unique field for every citation in the database. Of course, I can re-purpose one of the user fields, but I'm unclear on which ones are unused by every reference type.This edition of the MLA Style Manual also presents a significant revision of MLA documentation style. Notable changes include the following:
* The addition of the medium of publication as an element in entries in the list of works cited
* Inclusion of the issue as well as the volume number (when available) in every entry for a journal article in the list of works cited
* Simplified guidelines for citing works published on the Web (see 6.7)
* New guidelines for citing digital files, graphic narratives, and press releases
* Additional refinements aimed at simplifying and standardizing the formats for entries in the list of works cited
Another change not listed in the above list is that a few things are now required that never were before. I don't have the copy of the manual on my, but my impression is that "Access Date" will now be required for a far greater range of reference types, so a unique field for access date would be helpful. (In some reference types "Access Date" seems to be user 4? But in others that is used by "translator", am I correct?) And we're now going to need to identify the database from which we accessed certain types of things: I think that, for example, a journal article accessed via JSTOR will need JSTOR in the citation somewhere. A dissertation abstract found in ProCite will need ProCite somewhere.
I think all these things are doable by me, slowly and laboriously changing user defined fields and updating my references, but I wonder if there are easier ways...
