Star Trek fans invented modern fandom, and many of us produce fantastic content.
The Inglorious Treksperts: Sit down with a group of people who know their Trek and have also worked on Trek in some capacity. More than once, I have finished an episode and then immediately listened to it again. The information is that good.
Enterprise Incidents: There are a thousand rewatch podcasts, but none dive quite as deep or deliver the same amount of raw enthusiasm as Steve Morris and Scott Mantz. The podcast is currently going through TOS in production order and I can only hope the guys keep trekking through TAS.
Mission Log: The hosts cover every episode of Star Trek (yes, including The Animated Series) one podcast at a time. If you’re new to this show, start with their TOS episodes.
Tales of the Unknown Redshirt: The TOS background actors, stunt performers and doubles don’t get enough credit. This page delivers thoroughly researched insights into the people who often died for our benefit. You will learn new things.
Star Trek Fact Check: Deeply researched TOS production articles.
Star Trek Prop Authority: A remarkable resource on TOS costumes, props and auctions.
Trek Core: Audio clips, photos, schematics, screencaps. Stop by for a ringtone, stay for hours.
Starlog at Archive.org: All 374 issues of this iconic magazine are available to download.
