Thank you for your question about finding French translations of English books.

A website you may find very useful for this is UNESCO's "Index Translationum", which contains over 1,800,000 titles. It will tell you what languages a book has been translated into, as well as the titles in those languages. Note that you don't have to fill in every field on their search page - for example, if you were looking for a translation of Jodi Picoult's "My Sister's Keeper", you could just put "picoult" in as the author, and "keeper" in as a title word, and that search gives you 15 results of translations in different languages. If you only wanted results in French, you could specify French as the target language on the search page, and that would give you just one result, "Ma vie pour la tienne". You can find their search page here: http://databases.unesco.org/xtrans/xtra-form.shtml

If the Index Translationum website doesn't have a book you're looking for, you could also try WorldCat, which is a database of the collections of hundreds of large libraries. For example, if you go to their Advanced Search page (see link below), and type in "picoult keeper" as keywords, and pick French out of the language menu (at the bottom of the search page), then click on the Search button, you will get a result of "Ma vie pour la tienne". http://www.worldcat.org/advancedsearch
