About
An index built against the grain of the modern internet
The problem
Most of what reaches you now is optimised for a metric that has nothing to do with whether it is true or whether it makes you better at anything. Recommendation systems select for engagement. Generative tools have made plausible-sounding filler effectively free. The result is not a shortage of information but a collapse in the cost of producing things that look like information.
The scarce thing is no longer content. It is knowing which content is worth the hours.
What this is
Project Sherlock is a directory of subjects and a library of works, both curated by hand. The directory covers 39 domains, 449 fields and 4,673 topics — organised the way the disciplines actually divide, not the way a homepage would prefer. Engineering opens into mechanical, aerospace, electrical, civil, chemical, nuclear and fourteen more. History divides by period and region, then by civilisation. Nothing is left as a catch-all bucket.
The library currently holds 5955 works. Each states its actual argument in a single line, so you can decide before you commit.
Inclusion criteria
- It teaches a model, not a factEntries are chosen because they change how you think about a domain, not because they contain trivia about it.
- It is checkableEvery entry names a real author, a real year and, where legally free, a direct link to the original.
- It has survived scrutinyPreference goes to work that has been argued with in public. Where a famous work has been substantially challenged, the entry says so.
- It is not fillerNo listicles, no engagement-optimised summaries, no machine-written overviews of things that already have primary sources.
How to use it
Start with the directory if you want to map a field before entering it — the outline view shows every field in one screen. Start with the library if you already know roughly what you want and need to pick the right entry point. Search covers both.
How the links are kept honest
A free copy that has moved or died is worse than no link at all: the entry still renders as something to click, and the reader finds out it is broken only after trying. So every link in the library is refetched on a schedule — 4,643 of 5,236 so far, most recently on 17 September 2026.
When one dies we go and find the work again rather than quietly dropping the entry, and every repair is published with its date — 1,227 so far. That record is also the honest answer to how much of this is maintained rather than merely assembled.
Who maintains it
Project Sherlock is published by COVIS Labs. Selection is editorial and is made by hand against the criteria above — where a choice is contested, the entry says so rather than presenting a judgement as a fact.
Corrections are welcome and are the fastest way to improve this: if an entry misstates what a work argues, attributes it wrongly, or links a copy that is not what it claims to be, tell us and it will be fixed or removed. Works considered and left out are listed, with reasons, at what is not here.
On the taxonomy
Any classification of knowledge is a set of arguable choices. Subjects overlap, and several here legitimately belong in more than one place — behavioural economics sits between psychology and economics, biophysics between two domains that each want it. Where that happens the topic appears under the domain whose methods it uses, and the neighbouring domain links across. The structure is a navigation aid, not a claim about the true shape of knowledge.
