Confusing submission guidelines

I need to use this as an illustration of confused document guidelines:


How should a manuscript be prepared for initial submission?
As of Volume 11 of LD&C (2017), authors submitting manuscripts should follow the Generic Style Rules for linguistic publications and the LD&C Style Sheet. LD&C formerly used the Unified Style Sheet for Linguistics. Authors are also expected to include a brief (no more than 200-word) abstract with their submission. Authors may use British or American English spellings as long as they are consistent within one article.

Manuscripts should be anonymised, please do not include author name(s) or email addresses, and make sure that the document properties do not include the author’s name.

A Citation Style Language (CSL) template for use in Zotero or similar tools can be found here. A very useful guide to using CSL can be found here.

What are LD&C‘s style conventions for published articles?
Language Documentation & Conservation editorial style follows The Chicago manual of style, 16th edition (Chicago: University of Chicago Press, 2003) and the Generic Style Rules for linguistics.

Citation of primary data
For researchers in the field working with datasets, we encourage the use of the Tromsø recommendations for citation of research data, both in the bibliography and in the text of linguistics publications.
