Learning from Wikipedia

Hello Rabbi. Recently, I have been awakened by a great desire to expand and organize my knowledge in a variety of fields, including history and philosophy.
I am really driven to want to know what happened in the past in human culture in general and Israeli culture in particular, and in doing so, to also know the words of the days of thinkers and figures who were active at that time and to get to know their thoughts and their intellectual imprint.
I am currently unable to study in an organized framework at the university and in fact I am collecting materials on my own and editing them alone. I wanted to ask your opinion about the information offered on Wikipedia – is it a legitimate and good place to gather and acquire knowledge (even if it is initial and basic in order to build infrastructure) in these fields and in general?
I would also like to receive guidance on where to start and how to do it in general? How do we approach creating a neat and organized structure of information in these fields?
Thank you, Yehuda.
