This site doesn't allow questions that ask us to recommend Free & Open works such as software, libraries, media, or services. There are a few reasons why these are not constructive questions:
- They are usually quite subjective. No one can tell you what the 'best' library is; you will need to try a few and decide.
- Unless the request is extremely specific these questions are just setting everyone up for disappointment when the question asker says to those who are trying to help "That's not what I was thinking of." We're not mind-readers!
- In general no one will be able to find what you're after faster than you can yourself. Even the best intentioned of these questions end up just resulting in someone shifting their work to someone else.
But we still want to help! This post contains a long list of websites where you might be able to find what you're after.
