BLS has a number of journals that specifically address bioethics issues, many of which are listed below. Keep in mind that many general medical journals like JAMA, New England Journal of Medicine, and Lancet also cover these topics, and can be accessed via the proxy server or with a Westlaw or Lexis password.
Using topical databases that aggregate abstracts and/or full text of articles from a number of different sources is an excellent way to begin researching a multi-disciplinary topic. Remember that if you locate an abstract that seems useful, the next step is to search Find A Source for the title of the journal to see if BLS subscribes to that journal. If the publication is not available through BLS, the article can be ordered via Interlibrary Loan.
There are also general academic databases that may contain articles and/or abstracts on point, such as JSTOR, Academic Search Premier, and Social Science Research Network (SSRN), as well as Journals and Law Reviews on HeinOnline, Westlaw, and Lexis.
Westlaw has a range of medical journals, including the New England Journal of Medicine. It also includes many sources on bioethics and ethics in medicine:
