| Source Type | Example | Reliability | |-------------|---------|--------------| | Travel guide sites | ParisInfo.com, TheLocal.fr | Moderate – often repackage official PDF but may host old versions. | | OpenStreetMap derivatives | OSM-based transit maps | Good – community updated, but not official. | | “Printer-friendly” versions | Monochrome, simplified maps | Variable – may omit recent changes (e.g., Line 14 extension to Orly airport). |
