Manuscript Preparation for Submission and Publication
Some journals require authors to submit a short list (3-10) of keywords with their manuscript. These descriptors may be provided by the author as the terms the author believes represent the key topics presented in the article, although the keywords supplied by the author are not what PubMed or other bibliometric databases use. Some journals provide a standard taxonomy of terms that authors may select from when submitting their manuscript. These may also be used by some journals to categorize manuscripts and help guide the selection of peer reviewers. Many journals publish keywords, as submitted by authors or as edited by indexers or as tagged semantically (see 22.1, Glossary of Publishing Terms) for journal websites, including them with the articles, in online tables of contents, or both, to aid online search and discovery.
