Note: This SIFT method guide was adapted from Michael Caulfield's "Check, Please!" course. The canonical version of this course exists at http://lessons.checkplease.cc. The text and media of this site, where possible, is released into the CC-BY, and free for reuse and revision. We ask people copying this course to leave this note intact, so that students and teachers can find their way back to the original (periodically updated) version if necessary. We also ask librarians and reporters to consider linking to the canonical version.
As the authors of the original version have not reviewed any other copy's modifications, the text of any site not arrived at through the above link should not be sourced to the original authors.
