Like a book. A book has a cover to judge the book. A cover is a title and author and genre and at the back a short description of the content of the book and possibly the author. The first page has publishing date and when it was written. The Preamble is a longer description and at the end the appendix additional information followed by a list of chapters, the index lists important keywords and the pages to find them.
A library is a sorted warehouse of books listed by Genre, Author and publishing date showing the side with tbe books title.
And since computers it all can be in searchable and sortable databases....
But we need guns to protect them and the readers in this coming Cyberpunk WW4 in which those promoting ugly and stupid will get killed by burning love against their acidic hate.
