This is a great idea. I love books. I love collecting them and reading them.
One thing I've learned in my studies is that context is important. Because every work has to establish some level of credibility in the reader before they will engage with it, it could be useful to know the significance of each book in the list. You are interested in removing books from the list in order to make it less overwhelming, which is an attempt at this exact thing. If certain books are known to be filled with shoddy ideas and have been rejected by the community, that context is important. Likewise, books that have established a reputation as must-reads should be represented as such.
I am unfamiliar with most of the books on this list, but will keep this project in mind. Would you be able to provide any information about how you assembled the list? How was each book included? Getting that kind of information could give the list some very unique value. One of the reasons people go to universities, after all, is because they want to read texts that have been vetted by a professional group of scholars.
