May a publisher provide only a subset of its articles or journal content to PubMed Central?
Every journal that is accepted into PMC is encouraged to deposit its complete contents (original research, review articles, commentaries, editorials, letters, news items, etc.) in order to create a credible digital archive of the journal. A journal may choose to exclude certain types of material but, in most cases, must deposit all its primary research content, at a minimum. The exception to this minimum requirement occurs in the case where a publisher agrees to deposit all articles that fall under an open access or similar program covering selected articles from a range of journals. Examples of such programs are Blackwell Publishing’s Online Open, Oxford Journals’ Oxford Open, and Springer’s Open Choice.
