**EROS resources** As part of our mission to provide guidance and training, we have compiled a selected list of freely available tools and resources that can help researchers understand and adopt open practices. The goal of this collection is to provide a starting point for researchers wishing to, e.g., - Find a practical introduction to the whys and whats of open science - Learn about the benefits of open science, including multi-site collaboration and reproducibility - Make use of open resources (e.g. open source software and Creative-Commons-licensed materials) to minimize restrictions on sharing and verifiability - Pre-register a study in public archives or via journals (Registered Reports) - Learn about optimal reporting, statistical, and scientific practices to ensure reproducibility - Archive and publicly share their study data, code, and materials to the maximum extent permitted by ethics and privacy law - Understand funder and journal policies related to open data and open access.
