About
How this library works
Res Publica is a free, nonpartisan, open-source library. It is built so that you can check every claim it makes: where each text came from, how each passage is numbered, and who connected two passages and why.
Where the texts come from
- Download. Each source is downloaded once from a public-domain original, and its address, date and checksum are recorded.
- Import. A program splits the original into passages. It may collapse spacing and remove markup, but never changes a word, a spelling or a mark of punctuation. Original spellings such as “chuse” and “defence” stay.
- Verify. Before anything is published, every import is run again and must reproduce the published text exactly, so no passage can be retyped or “corrected” by hand.
- Flag, don't fix. Suspected transcription errors are listed in a public errata log for a person to check against a page image.
Every passage has a permanent address
References are short names that never change once published. Link to one, cite one, or type one into search.

Connections and review
A connection says how two passages relate: one quotes, cites, responds to orrebuts another, a case interprets a clause, and so on. Each one records why it was made, who or what made it, and whether a person has reviewed it.
- Suggested Proposed by a machine and not yet reviewed by a person. Shown with a dashed border.
- Reviewed Checked by a person.
- Overruled A case that a later decision overruled, recorded with a source for that fact.
Any quotation shown in a connection is checked by code against the text, letter for letter.

The ratification debate: texts read from scans
The essays and letters of the ratification debate come from three collections printed in 1888 and 1892, now in the public domain. No accurate digital text of them existed, so Res Publica reads them from the Internet Archive's scans of the printed books:
- Layout. One scan's OCR gives the words and their place on the page. Running heads, page numbers and footnotes are set apart, and a paragraph broken by a page is joined again.
- A second reading. Each word is compared with the OCR of another scan of the same printed edition, made from a different copy of the book.
- A vote, with limits. Where the scans differ, the reading most scans share wins, or the one that is an English word found in a clean text. A real word is never swapped for a different real word, and figures that differ are never settled by vote.
- Doubt is shown. Words no rule settles are kept as the main scan reads them and underlined with dots. Select the paragraph to see each scan's reading and a link to the page image.
No word is typed by hand. Errors that every scan shares cannot be caught this way, and the newspaper headings, set in display type, are read worst; please report what you find. Which side a writer took is Res Publica's grouping; authors are as the editions give them, and several of those attributions are disputed.
Brutus, one of the most important Anti-Federalist writers, is not here yet: none of these collections prints his essays, and no other public-domain printing has been found that can be imported and checked.
