This list of software and tools is by no means comprehensive. If you want a more comprehensive list, see the Collections platforms & tools page on the Digital CoLab's guides site. However, the list below includes tools that I think are feasible to learn and use within a semester. There's no coding involved in any of them and they all have easy-to-use graphical user interfaces. Additionally, many of the tools on this list have good step-by-step guides and documentation for how to use them, so you have a resource in case you encounter an issue or get stuck.
If you have any questions or need help, email me, Kiran, at kam535@cornell.edu.
