Too Long; Didn't Read
If you have a glass-protected bookshelf, that will protect your books from dust and insects, but it will cost you more time to access the books when you need them. Because you first need to slide or open the glass and then can get the books. On the other hand, if it’s an open bookshelf, that will give you quicker access but you will lose the protection. Similarly, if you organize your books in lexicographic order of their name, you can easily search for a book if you know it’s name. But if your bookshelf has cases of different size and you organize your books based on their size, it will look nice, but can you find a book in a hurry? I don’t think so.
