I was recently reminded about the tool Zotero and re-downloaded it onto my laptop. It is right on time as I am becoming increasingly dis-organized in my writing project. I have read so many books that I am starting to forget where the cool stuff is that I have marked out in these books. Zotero allows me to enter these books and "tag" them with terms that I can later search for, bringing those books back up and reminding me that a particular book discusses, say, contextualization of the gospel. Here is the promo video.
