Hello, I am looking for someone who can help me find and provide digital PDF versions of French encyclopedias from the 1970s and 1980s. In particular, I am interested in collections such as: Clartés (Éditions Techniques) Encyclopédie Alpha Encyclopédie Bordas I need the complete sets (or as complete as possible) in French. Please let me know if you have access to these archives or if you can help me locate them in digital format. Thank you in advance for your assistance.
