- What are the objectives of the website? The Henri Poincaré Papers website aims to facilitate scholarly access to Poincaré's works. Launched at the University of Nancy 2 in 2002 by Scott A. Walter, the site was ported to a server at the l'University of Nantes in June of 2016. Since then, the University of Lorraine has hosted a mirror.
- Who is behind the website? The Henri Poincaré Papers website is a joint undertaking of students, scholars, and staff affiliated with the Henri Poincaré Archives (UMR 7117) in Nancy, and the François Viète Center (EA 1161) in Nantes. The transcriptions were established with the collaboration of the following scholars: É. Bolmont, O. Bruneau, A. Coret, A. Csiszar, A. Gharnati, G. Heinzmann, Ph. Henry, C. Jullien, R. Krömer, A. Moktefi, Ph. Nabonnand, L. Rollet, M. Schiavon, T. Volpe, and S. Walter. Editorial assistance was provided by S. Aksin, P.-E. Bour, C. Clozza, P. Doh, M.-C. Duchenne, S. Hannaire, A. Husson, S. Jokulsson, A. Klein, M. Lagarde, R. Nazin, G. Schuppert, M. Sakhri, and A. Tiusan. The website was designed by S.A. Walter, and realized by P. Couchet.
- Who pays the bills? The Poincaré Papers Project has received generous funding and support from the Agence Nationale de la Recherche (Project Corpus-2006: SSM20: Sources of mathematical knowledge in the early 20th century), the Lorraine Region, the Urban Community of Greater Nancy, the National Center for Scientific Research (CNRS), the University of Nantes, University of Lorraine, the Maison des Sciences de l'homme lorraine, the Maison des Sciences de l'homme Ange-Guépin, and the François-Viète Center (University of Nantes, EA 1161).
- Who is responsible for the website content? Scott A. Walter edits the Henri Poincaré Papers website; please direct your comments, queries, complaints, and suggestions to him.
- How do I access the transcriptions and images? There are three methods available, two of which are accessible under the "Correspondance et Varia" banner. Choose "Inventaire" to use a search form, or "Édition" to get a listing by volume. The third method (available only via the website hosted by the University of Nantes) covers all the documents of interest, including images, via document metadata and full-text hashes. This method requires entry of a term (or several terms) in the search box located in the upper-right-hand corner. Results of the search are returned according to the document class (publications, correspondence, varia, reports on doctoral theses, biographical notices, commentary). To refine the result set, combine search terms with Boolean operators [ | - ! ( ) ]. The full-text search component is morphological, based on rules of French grammar.
- What is your transcription policy? Page breaks are indicated only in the Mittag-Leffler correspondence, and then by a forward slash (/). Paragraph breaks are always reproduced when indicated unambiguously in the MS; otherwise, breaks are introduced at the editor's discretion. Transcriptions are diplomatic: spelling errors are silently corrected, and variants neglected at the editor's discretion. Transcriptions of mathematical formulas may feature extra parentheses not found in the MS. These are added when necessary to enable browsers to display formulas with nested fractions. Likewise, certain symbols (TeX macros) have been substituted on occasion due to browser font limitations. At the discretion of the editors, textual variants are indicated in footnotes, where struck-out passages are reproduced with strikeouts. Document type is indicated at the end of each transcription in boldface, followed by information about its location. A list of document codes is provided here.
- The transcriptions look strange. How do I configure my browser to get the right display? Some adjustment to your browser may be required in order to render symbols and accented characters correctly. All pages employ unicode character encoding (UTF-8), so you should verify that your browser is configured to render this encoding. You may also need to acquire fonts. For Debian users, the mathematica-fonts package is recommended. Math symbols are represented using MathML; for configuration of Firefox or Mozilla, see the MathML in Mozilla page. For hints on the configuration of other browsers, see the Stanford Encyclopedia of Philosophy. For users of Internet Explo*er, a free plug-in is available from Design Science.
- Some mathematical formulas are displayed as LaTeX markup. How do I fix this? This is a browser problem. The transcriptions are coded in MathML, except in a few places where MathML fails, in which case we code in LaTeX and rely on MathJax for display. Try switching to a different browser, like Google Chrome, which requires no configuration. The iPad Chrome app renders MathML-encoded formulas, but does not allow access to notes (hovering is unavailable). Other browsers may require a plug-in for display of MathML; a free plug-in is available from Design Science.
- The math symbols don't print properly from my browser. How do I fix this? It's not a fix, but you might try printing the PDF version of the document.
- How can I make the digitized image fit on one printed page? The images are scaled to fit on an A4 page. Margins can be adjusted in the page setup of your browser. Otherwise, you might try saving the image locally (by right-clicking), opening it with image-processing software (such as The Gimp), and printing it from there.
- Will all the letters be transcribed? Yes, all the letters will be transcribed. Poincaré's correspondence with G. Mittag-Leffler, and with physicists, chemists, engineers, astronomers, and geodesists has been transcribed in its entirety. The correspondence with mathematicians and with non-scientists (Volumes 4-6) will follow by the end of 2018.
- How often is content updated? New transcriptions are added on a weekly basis, and existing transcriptions are corrected as part of the ongoing editorial process. Every transcription features a time stamp indicating the date of the most recent edit.
- Who owns the copyright? The images on this site were created from many sources. Most of the images were established from documents from one of the following four sources: the Archives of the Academy of Sciences (Paris), the Library of the Institute of France (Paris), the Nobel Archives of the Royal Swedish Academy of Sciences (Stockholm), and a private collection. A stamp on each image indicates the holder of copyright. Unauthorized reproduction of the images on this website is prohibited. All transcriptions and annotations on this website are subject to a Creative Commons licence (CC BY-ND 4.0).
- How do I cite the documents on the website?
There are two cases to consider. Digitized images
should be referenced according to the copyright on the image, for example:
- The Nobel Archives of the Royal Swedish Academy of Sciences, Stockholm. Letter transcriptions and editorial material should be referenced as follows:
- Scott A. Walter et al., eds., Henri Poincaré Papers, Doc. N-N-N, http://henripoincarepapers.univ-nantes.fr, accessed on YYYY-MM-DD.
- Who wrote the annotations?
The documents are the result of a collaborative, ongoing effort, such that precise attribution of authorship is pointless for the electronic edition. However,
the editors of the first paper edition (published by Birkhäuser) are easily identified, according to the following table:
Volume Editors Year of Publication 1 Philippe Nabonnand 1999 2 Scott A. Walter, ed., Étienne Bolmont & André Coret, ass. eds. 2007 3 Scott A. Walter, ed., Philippe Nabonnand, Ralf Krömer & Martina Schiavon, ass. eds. 2016 4 Philippe Nabonnand, ed.,Olivier Bruneau, Philippe Henry, Jean Mawhin, Klaus Volkert & Scott A. Walter, ass. eds. 2018 5 Laurent Rollet 2017 6 Laurent Rollet 2019
- Have the documents on the website appeared elsewhere? The documents held in a private Parisian collection were reproduced on microfilm (35mm, B/W) by A.I. Miller in the 1970s with support from the American Institute of Physics. This microfilm can be consulted at the Niels Bohr Library and Archives (College Park). A selection of Poincaré's correspondence with mathematicians was edited by P. Dugac in volumes 7 (1986) and 10 (1989) of the Cahiers du séminaire d'histoire des mathématiques. Some of these transcriptions have been verified and reedited on this website. Others will follow.
- How do I get at the hoverboxes? Try right-clicking the call number. This ought to "freeze" the note, allowing you to access the link. Alternatively, try increasing the page magnification.
- Are there any websites similar to this one? Yes, indeed. A subset of Poincaré's correspondence may be consulted at the MPIWG-Berlin website. If you like reading Poincaré's letters, you will probably enjoy perusing those of his contemporary Arnold Sommerfeld, those of Charles Darwin, as well as Darwin's manuscripts, the letters of the great mathematician Carl Friedrich Gauss, the brilliant physicist André-Marie Ampère, or the 17th-century mathematicians and philosophers G.W. Leibniz and Isaac Newton.
