The PubMed database may be searched for online books, book chapters and documents from the NCBI (National Center for Biotechnology Information) Bookshelf Collection.  This collection provides free access to publications in life sciences and healthcare.  To retrieve book titles, book chapters and documents related to disasters, for example, use the following strategy: (disaster OR disasters) AND (pmcbook OR pmcbooktitle OR pmcbookchapter).

It is sometimes useful to have a list of MEDINE journal titles categorized by their subject areas.  The web page,  Broad Subject Terms for Indexed Journals, provides this information for 120 subject areas.  The page is under the auspices of the National Library of Medicine.  This document can be useful for conducting a PubMed search for articles on drowning, for example, where you want to limit the output only to Emergency Medicine journal titles.

A video is now available which provides an overview of the latest version of  EndNote, the bibliographic management tool useful for inserting footnotes into manuscripts.  Some features of version X6 that are demonstrated are the ability to apply ratings to the more important references and to view PDFs with a built-in PDF viewer.  In addition, text in a PDF can be highlighted.  The video is under 5 minutes long.
