You should look at web sources that have recently been updated because a lot of times new information is present that could change the original point/evidence. This could discredit the source. You also should do this because the newer the information, the more credible it is in the time (older information could easily be outdated).
Just keep at it! The only way to learn a new language is to keep studying and working at it. I wish you the best of luck!
