The ARTFL Encyclopédie Reader app is a text search and retrieval interface that interacts with a fulltext-searchable version of the Encyclopédie of Diderot and d'Alembert running remotely on the ARTFL Project's servers at the University of Chicago. Users can do simple word or bibliographic searches and, from search results, link to larger text sections. The "Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers, par une Société de Gens de lettres" was published under the direction of Diderot and d'Alembert, with 17 volumes of text and 11 volumes of plates between 1751 and 1772. Containing 74,000 articles written by more than 130 contributors, the Encyclopédie was a massive reference work for the arts and sciences, as well as a machine de guerre which served to propagate the ideas of the French Enlightenment. The impact of the Encyclopédie was enormous. Through its attempt to classify learning and to open all domains of human activity to its readers, the Encyclopédie gave expression to many of the most important intellectual and social developments of its time. To browse tables of contents of volumes, either touch the highlighted "touch here" link on the home page or touch the information icon in the bottom right of the screen and select "Browse by Volume." To search or retrieve texts, touch the three line icon at the top left of the screen. A search form drawer will toggle on the left side of the screen. To search for occurrences of a word in the database, fill in the "Search terms" field. Search terms are not accent sensitive: for example, entering "eclat" will return all instances of "éclat". Note also that wildcard characters will expand search terms. For example, "amour.*" will retrieve instances of "amour," "amoureux," "amoureusement," etc. The default report for word searching is a concordance report. Search results are displayed 25 at a time. Use the arrow buttons at the top of the screen to click through results. Touching a list item will retrieve a larger chunk of text for reading. To generate a word frequency report by various bibliographic parameters, scroll through the picker menu under "Choose a search report". Results will display in a complete list. Touch links to retrieve a concordance report for the individual frequency results. To delimit word searches by author, title, or other bibliographic parameter, fill in the specific field and hit submit. To do a basic bibliographic search, enter terms only in the author, title, or classification fields and hit submit. Note: search suggestions are enabled for bibliographic fields. However, once one of the fields has been filled in, suggestions will not pop up for the others. When reading a text section, click the arrow buttons at the top left portion of the screen to retrieve previous or next text sections, if available. To see the image of a specific page, touch the page number link and an image will download. Touch plate legend images to download high-resolution versions of the image. To bookmark a chunk of text, touch the bookmark icon at the top of the screen. A menu with any existing bookmarks will pop up, as will an option to bookmark the current page. To retrieve or delete a bookmark, touch the item in the list. From the dialog, select either "View text" or "Delete bookmark."
