Many of my blog posts contain links to reference books, websites, and information sources. Additional sources can be found in the list of links in the sidebar to the right, especially in the “Libraries & Research” section. Below are links to some source-related post categories:

The Writer’s Bookshelf

Reference link collections

Reference websites

Digital collections

Reference books

Update January 2015: Intute and Infomine, two excellent reference link collections, have disappeared from the web, so I’ve removed their links.
