Understanding the Who Classic Episode Guide Problem
Most people trying to find reliable episode information for classic Doctor Who run into the same wall pretty quickly. The BBC's own archives are incomplete, the Wikipedia pages vary wildly in quality depending on which editor touched them last, and fan-maintained databases tend to rotate through periods of heavy neglect followed by panic-edits. I spent about six months cross-referencing material before I settled on a workflow that actually held up. The core issue is that "Who Classic Episode Guide" means different things to different people. Some want broadcast dates, credits, and synopsis summaries. Others are looking for production codes, missing episode reconstructions, or DVD release histories. Those are three completely separate datasets that no single source covers well.
Who Classic Episode Guide: Where the Data Actually Lives
The two sources I come back to most are the BBC Doctor Who pages and the ISBT website, with the Big Finish wiki and Troughton Wiki filling in the gaps. The ISBT database is particularly useful because it tracks the exact transmission order rather than the production order, which is not the same thing for anything produced before 1989. The production order matters for continuity work. The transmission order matters if you're trying to watch the show as it originally aired. They diverge significantly during the Pertwee and early Tom Baker eras. For the Hartnell and Troughton periods, the situation gets worse. The BBC destroyed a large number of recordings between 1967 and 1970, and the remaining footage exists in multiple edit forms depending on which home video release you started from. A story like "The Web of Fear" has at least three different runtime versions floating around. If you pull an episode guide from just one of those sources without checking the others, you will get the wrong duration, and possibly the wrong episode count for stories that were partially reconstructed.
Building Your Own Reference
I stopped relying on any single site after I noticed that the Doctor Who Reference Guide entry for "The Daleks" listed a different first broadcast date than the ISBT, and both disagreed with the original TV Times schedule I found in a microform archive. That kind of discrepancy doesn't happen often, but when it does, it's in the stuff you'd check first. My setup is a simple spreadsheet with columns for story title, production code, transmission dates per episode, runtime, current availability status, and source notes. I use the Big Finish production list for production codes because they're consistent, then verify broadcast dates against ISBT, then check runtime against the BBC's own filmography where it exists. When those three conflict, I default to ISBT and flag the entry for manual review. That takes about twenty minutes per story if you're careful. Roughly three hours for a full serial in the classic era if you include the availability tracking. The payoff is that you can open the sheet and immediately see which stories have conflicting data and need a second look, instead of finding out three weeks later that your viewing order was wrong because you followed a single outdated wiki page.

Practical Use Cases
If you're building a watch order, stick to transmission order for the classic series. Production order makes sense for pre-2005 stories only when you're analyzing narrative continuity across serial boundaries, and even then it gets messy because production schedules overlapped with filming blocks in ways that don't map cleanly to screen order. If you're looking for which episodes survive, check the ISBT missing episode tracker alongside the BFI's holdings list. The ISBT data tends to update faster when new discoveries are made, but the BFI list is the more authoritative source for what actually exists in the archive. They disagree occasionally on borderline cases involving regional station holdings or private collector material. For DVD and streaming availability, treat every online listing as potentially stale. I've seen episodes listed as available on BritBox that weren't actually cleared there yet, and regions that dropped titles without warning. The most reliable approach is to check the specific storefront directly rather than trusting an aggregator.
Common Pitfalls
The biggest mistake people make is assuming that a story's episode count is fixed. Several serials from the Jon Pertwee era ran for more episodes than their standard six-episode slot, and some were edited down significantly for home video. "The Three Doctors" is seven episodes in broadcast order but some re-releases compress it differently. "Planet of the Spiders" is six episodes but the final episode runs much longer than usual. If your guide doesn't note these variants, you'll plan around the wrong runtime. Another issue is the split between UK and US broadcast orders. Some stories were re-edited and repackaged for American television in completely different episode groupings. If you're using a source that pulls from US listings without labeling them, you'll end up with a guide that doesn't match either version correctly. For the William Hartnell period specifically, some episode descriptions online are reconstructed from scripts rather than verified against surviving footage. That's fine for plot summaries but dangerous if you're using them for factual claims about what actually appears on screen. I learned this the hard way when I followed a script-based description for "The Savages" and it described a scene that wasn't in the surviving film. The script had more material than the final edit.
When to Walk Away from the Data
There's no point trying to build a perfectly accurate episode guide for the early William Hartwell serials beyond the first few stories. We simply don't have the material, and any claim to completeness is inaccurate. For those, the best you can do is track what's known from production records and be explicit about the gaps. The ISBT marks this clearly in most cases, which is why it stays in my workflow even when it's frustratingly sparse. If you want a ready-made starting point, the ISBT Doctor Who database at isbt.org.uk remains the most consistently maintained free resource. It won't solve every problem, but it's better than whatever random wiki page you'd land on after a Google search. From there, cross-referencing with the Troughton Wiki and the Big Finish wiki covers most of the remaining uncertainty for any given story.
