What You Need to Know Before Downloading a Great Fire of London 1666 PDF
You can't just download a single PDF and call it a complete source on the Great Fire of London. Most files floating around the internet are either low-quality scans, outdated compilations with broken links, or AI-generated summaries that got basic facts wrong. I spent about three weeks last year tracking down reliable digitized primary sources after a student in my class tried to use a Incendio De Londres 1666 Pdf from a random file-sharing site and cited it in a paper with incorrect casualty numbers. The British Library holds the most comprehensive collection of digitized material on the fire. They've scanned the original weekly bills of mortality, court records, Samuel Pepys' diary entries (published later but sourced from the fire period), and several maps showing the pre-fire and post-fire layout of the City of London. These are free to access. The National Archives in Kew has coroner's inquests and property damage claims that haven't been as thoroughly digitized, so you'll hit paywalls or find incomplete records if you only use one source. I once downloaded a PDF labeled as a complete compilation of fire documents and spent two hours cross-referencing before realizing half the transcriptions were copied from a 19th-century source that had its own errors. The workaround was going back to the British Library's site directly and pulling the original scans, then checking dates and spellings against the National Archives catalogue. It took longer but the data was actually correct.
What Most PDFs Get Wrong
Beginners tend to trust any PDF that claims to cover everything about the Great Fire. Here are the issues I've consistently found: Death toll figures vary wildly. Some sources say zero confirmed deaths, which is technically true based on surviving records. Others claim over ten thousand. The real answer is that no complete census of victims was compiled at the time, and the "official" low number reflects bureaucratic gaps rather than actual events. Any PDF that states a precise death count without qualifying it is either poorly researched or deliberately sensational. Maps are often misaligned with modern streets. A lot of downloadable PDFs paste in John Ogilby and William Morgan's famous 1676 map of London but don't note that the fire destroyed areas between 1666 and when that map was made. Reading building locations off those maps without cross-referencing fire district records will give you the wrong answer about what was where.
Samuel Pepys is over-cited and under-contextualized. His diary is essential but it's a personal account, not a historian's record. He wrote about events days or weeks after they happened in some cases, and his observations are limited to areas he personally walked through. A PDF that treats Pepys as omniscient is doing you a disservice.

How to Actually Use These Sources
Start with the British Library's "Great Fire of London" portal. It links to transcribed documents, high-resolution images, and the database of displaced residents. From there, if you need primary legal documents about property disputes that arose from the fire, go to the National Archives catalogue and search for E 134 (Exchequer: Receipt: Fire of London, Claims). Those files are not all digitized yet. You'll get scan-on-demand charges and a waiting period, but the originals contain information that secondary summaries consistently skip. The cheapest and most reliable route for a full read is Paul Hammer's edition of the fire records, which compiles court documents with annotations. It's available through academic libraries and sometimes through interlibrary loan. If you're not in academia, the British Library's free resources will cover most needs unless you're doing deep archival work. I've seen people try to compile their own PDF by saving individual pages from multiple sites. That approach breaks citation integrity and usually produces a document that's hard to navigate. Better to bookmark the key portals and pull specific records as needed rather than building a static file that will age poorly.
