Transcribing the Traité

Help to transcribe Otlet’s “Traité” from PDF to a digital full-text edition. No easily readable edition of his works is currently accessible online. While more and more books and articles are published about the “visionary of the digital age”, the original sources remain accessible only to those who are willing to download or browse a 200 MB PDF-file and understand French.

The first goal is to produce a digital edition of the “Traité de Documentation” in HTML and EPUB format. The tool of choice is the Sphinx documentation generator. It uses reStructuredText files as input.

The current version of the reST version can be found at . The rendered version is at .

To contribute to this effort just get a copy of the PDF of University of Ghent, open a text editor and start correcting the mistakes of the OCR run according to the rules layed out below.

Sphinx and reStructuredText

The digital versions of the Traité are generated automatically by the Sphinx documentation generator. Source files are written in reStructuredText format.

An overview of the reST syntax can be found at .

In the source files the headings need to be marked up in a specific way. We follow the convention which is used for the Python programming language.

  • # with overline, for parts and languages TdD

    • with overline, for chapters 1-5
  • =, for sections two-digit 11

  • -, for subsections three-digit 111

  • ^, for subsubsections 111.1

  • ”, for paragraphs 111.11

  • ., for 111.111

  • To compile: make html

  • To open the result

    • Linux: xdg-open _build/html/index.html
    • Windows: start _buildhtmlindex.html
    • Mac: ?

To use the Sphinx theme of ReadTheDocs locally just install it by:

pip install sphinx_rtd_theme

To avoid auto-enumerated lists when a paragraph starts with a number, the number needs to be escaped by a backslash \1. bla bla ...

Page layout

Pages should be structured like this:


*<pg-nr>* CHAPTER TITLE <section-nr>  (can be mirrored, depending on even/odd page)

... texttext texttext texttext texttext texttext
Before and after the chapter and section titles,
insert a unicode "wide space", copy-paste from " ", or U+3000

Line breaks should be placed as in the
original text, including hyphenation.
For more details on hyphenation, see below...

Paragraphs are separated by a blank line.
... texttext texttext texttext texttext texttext ...
After the first column (and optional footnotes) put at least one
blank line and then a horizontal bar ("----"):


next column texttext texttext texttext texttext texttext texttext
texttext texttext texttext texttext texttext texttext texttext texttext
text texttext texttext texttext texttext texttext


<section-nr> CHAPTER TITLE *<pg-nr>*

next page text ...
text ...

In detail:

  • Pages are separated by horizontal rules “====” surrounded by two empty lines above and one blank line below the rule.
  • After a single blank line, page numbers, section/chapter titles and section numbers should be placed just as in the PDF, pages in italics (surrounded by * asterisks.)
  • The two columns on each page are separated by “—-” surrounded by two single blank lines.
  • Header markup should be one symbol longer than the header text
  • Unicode characters should be used wherever possible, but should be documented somewhere
  • The original text, layout and typesetting should be represented as close as possible within the limits of the reStructuredText format.
  • Hyphenation: What is a good solution to somehow mark a hyphenation from the book in the reST format without it showing up in the compiled html? Leaving hyphenation in the reST would destroy full-text search. But single dashes (-) at the end of the line are easy to remove with a script. Soft-hyphens can be used to replace the hyphenation so that it doesn’t show up in the browser. An open question is how this will affect the epub output of Sphinx.
  • If the PDF resolution is not good enough to discriminate symbols accurately, just place three bold question marks ??? (surround them with two asterisks **???**) in this position.

The source files are encoded in unicode format (UTF-8 without BOM). To check the encoding on Windows, use the excellent editor.

To input specific letters or symbols:

Ubuntu12: Shift+AltGr + ^ + e = ê U+0152 OEvre Œ, Kleinbuchstabe œ U+0153

Multiplication sign: × (Unicode 215) Unicode composition: Another means to enter characters is to enter them as Unicode character number.

Press Shift+Ctrl+U, release U, enter the hexadecimal (0123456789abcdef) Unicode character code point, then release Shift+Ctrl. An underlined u followed by the number will be displayed as you type.

Alternatively, press (and release) Shift+Ctrl+U, then, while underlined u is displayed, enter the hexadecimal Unicode character code point followed by <Return>.
