==Explanation==
Some people like to sort their bookshelves by the visible color of the book's spine, for example by hue to create a rainbow effect. This is pleasing to the eye, but may be unhelpful when [https://www.youtube.com/watch?v=AYxmPHLU9oA trying to find a specific book]. Literary enthusiasts (AKA "Book People") frequently dislike this system, because it emphasizes appearance at the expense of making books easy to find. On a philosophical level, treating books as decorations, rather than reading material, upsets many purists.  "Book people" are more likely to have a practical system for arranging their books, either by category, genre, title, author name, or some combination of those.  For a large library, a more rigorous organizational scheme such as the {{w|Dewey Decimal Classification}} might be used.

Unfortunately, [[Randall]] has found a ''much'' worse method of book organization - instead of sorting the books as discrete units, he has sorted their individual ''pages'' by number. This would require physically separating each book into its individual pages, and then organizing them into groups by page number. This effectively destroys every book, and requires anyone trying to read them to laboriously find each individual page (among many pages of the same number), and then replace it in the correct space after reading. Adding a new book would require individually placing potentially hundreds of pages. Where pages are not numbered, finding their place would be nearly impossible.

He doesn't denote whether he's using any particular sub-method to sort the pages within each page number, and if so, whether this is consistent per book (e.g. alphabetically by the book title), or does each page number sort independently?  If the latter (e.g. each group of pages of a particular number is sorted by the first word or words on that page, similar to what is described in the title text), it would be especially difficult to reunite all the pages of a book as each page would be in a different location relative to the other pages.

From the picture, Randall's system appears to work by absolute physical page count, including the front and rear covers as 'pages'. All the front covers are on the left side, then the first internal leaf of each book (counted as the second page), then the second internal leaf, etc. This produces repeating patterns of taller and shorter loose-leaf pages, echoing the proportions of each cover, having gathered together a page of the same position in each different book. The back covers are mixed in to whatever group falls after the last internal leaf from the same book, and so are intermixed with pages from longer books. The left-most front cover matches the right-most back cover, the second front cover matches the 2nd-to-last back cover, etc. with the last of the front covers matching the first of the back covers. At the end, there are only the last pages of the longest book left, now all uniform in size, and its rear cover. 

From the number of repeated page patterns, it can be determined that the shortest (inner-most) book contains approximately 28 pages, the next shortest book has about 30, the next around 32, the next around 40, etc. It gets harder to tell as the number of pages in each group gets fewer and fewer. In total Randall's bookshelf contains 11 books.

The caption claims that "book people" get way angrier at this system, likely because it involves physically destroying books, rendering them almost unreadable. People with a strong affinity for books are often upset at volumes being treated with such disrespect. 

In the title text Randall claims he sorts his bookshelf alphabetically, but by the first '''sentence'''. He describes this as "the normal way", even though the typical practice is to sort books either by title or author.

Sorting by first line was, in fact, a common sorting method before books had titles, known as {{w|Incipit}}. In modern times, however, that method is wildly obsolete, as books are almost always identified by titles, few people memorize the opening lines of their books, and a film titled ''{{w|The Hobbit|In a hole in the ground there lived a hobbit}}'' would not receive any funding.{{Citation needed}} However, {{w|papal encyclicals}} are still named after their first words, and thus would be sorted after their first sentence. For example, the encyclical titled ''{{w|Quanta Cura}}'' begins with "''Quanta cura'' ac pastorali vigilantia Romani Pontifices Prædecessores Nostri, exsequentes [...]".

In somewhat similar fashion, the 114 chapters of the {{w|Quran}} are roughly sorted by their length. American church hymnals list hymns by relatively meaningless numbers, but then index them by tune name, text title, first line and meter.

Some books do have very well-known first lines, so sorting by first line could be used to demonstrate a level of literary sophistication on the part of the bookshelf owner, but could hardly be considered "normal".

Other pop culture references to sorting by first sentence occur in the Good Omens TV show season 2 episode 2, where the archangel Gabriel, while suffering from amnesia, reorganizes the books in the bookshop alphabetically by first sentence to pass the time.

==Transcript==
:[A bookshelf hanging on a wall is shown. It is covered almost from left to right but not with ordinary books. To the left there are 11 covers next to each other without any paper between them. They have different heights and shades of gray. After the last of these there follows many leaves of paper of differing heights similarly to that of the covers. The top of the papers thus form a wave shape with more than twenty peaks before they reach another cover. After that there follows similar patterns with paper in different height and then a cover in between more papers. But there is a much shorter distance between the first and second cover than before the first cover, after the initial 11 covers. The next two covers are close to the first, then there is a longer stretch of paper to the fourth, much less to the fifth, and then the next three covers comes very close. There is again quite long distance to the ninth and tenth cover, and here the number of different heights for the paper are clearly less than the previous paper stretches. Finally before the last and 11th cover all the paper, not much of it though, are of the same height, and just a bit lower than the final cover. The 11 covers at the start matches the 11 covers later, but do not come in the same order throughout the paper stretches as they are sorted to begin with. There is a caption beneath the panel:]
:Book people hate seeing books sorted by colors, but it turns out they get ''way'' more angry if you sort the pages by number.
