Site written and maintained by C Shepard.
Started: April 21, 1999. Updated last: Summer 2023.

I've included this bibliography for students, law enforcement, teachers and researches who want or need to trace my sources. I try my best to maintain a valid, informative site. I've spent the past years verifying the information presented here with people who were on the scene, and those who knew the people who were involved. To the best of my knowledge, this site is accurate and factual. In addition to the resources listed below, you can find Columbine-specific links and pages such as memorials and victims' family sites on the Links page.

Not linked here, but just as important are all the tips and contributions I've received from visitors to this site. Thanks for all the photos, files, and information you've sent, the personal stories shared, kudos and complaints and all the rest. Also, I'd like to acknowledge those who have written me to correct facts; the families of those involved; all of the websites and forums out there who share their info freely; Tiger Girl for being there on 4-20 and giving constant feedback during the early days of the site's development; everyone who's written to support this endeavor; and most of all my family for all the hours of my time they have sacrificed in order for this site to be the information repository it is today.
