After Tianling had this idea, he didn't have the interest to find the little "Liu Bei" anymore, but carefully inspected the library building.

There are five floors in the Son of Heaven Library, and Tianling has been drying the books on the first floor before, and he has never been to the other floors, so it is the first time he has come to the upper floors today.

Looking at it layer by layer, I know that the place of the books on each floor of the library building is actually regular, but this rule is relatively simple, that is, according to the price classification, the more valuable the book is placed on the higher floor, like some precious calligraphy and paintings and rare books are all placed on the fifth floor.

Tianling stood on the fifth floor and looked at the locked door, he couldn't help but roll his eyes, he didn't know how valuable the books, calligraphy and paintings inside were, but he knew that the emperor must be poor and crazy, look at this miser's style, tsk!

Looking at it in this circle, except for the fact that the fifth layer can't enter, Tian Lin doesn't know the situation, how many books are hidden from the first to the fourth floor, and Tianling already has a rough estimate in his heart.

Turned around and went downstairs to find a pen and paper, and wrote down the estimated situation, there is a way that a good memory is not as good as a bad pen, and the memory will sometimes be broken, and there will be confusion, which is not more true than white paper and black letters.

This is a habit that Tianling has retained from previous experiments, no matter how good his memory is, he will record and back it up on paper to prevent mistakes.

Although the Tianzi Library is not as good as a modern library, it is also huge in number and has a lot of content, and some books cannot be judged what the contents are based on the title alone.

In addition, Tianling also found a problem, that is, the materials of the books of this era are basically rice paper and silk, and there are also a small number of bamboo slips and wooden slips, and most of the bindings are horizontal lines.

Because the material of rice paper and silk is soft, it is impossible to stand up and place like modern books, and because it is a horizontal line binding, most of the books in the Son of Heaven Library are stacked in stacks, every time you take a book, if the book is placed on top of some fine, if it is pressed below, you can only take out a stack of all of them, and after taking out the books you need, you can fold them back one by one, which is extremely time-consuming and laborious.

And in this way, the classification and labeling can only be carried out horizontally, otherwise there will be a part of it that is pressed and blocked and cannot be viewed, but if the classification and labeling are horizontally, the words you see when you check them are horizontal, and the daily reading habits are to the left, and you can only tilt your head to find the book when you are looking for it.

Tianling does not have cervical spondylosis and does not need to be treated, so he has to find a way to solve this problem first.

The Heavenly Spirit picked up a book from the shelf and tried to stand it up, but the paper was too soft, and after standing up for a while, it fell softly. Tianling took two more books, and put them together with the books in his hand, trying to see if they could succeed in stacking them thicker, but this time the books that were together did not fall down, but the paper was crooked and twisted, and it was not regular at all.

Still no, Tianling Heart Dao, although it won't fall, but standing like this, it is estimated that it won't be long before the whole book will be wrinkled.

How can you stand up a book without crumplors?

The heavenly spirits are chattering, and they set up the book, and the book stands up, and the book stands up······

Hey? What was just said? Book stand?

That's right! Tianling's eyes are shining, just stand with a book!

Make a movable plywood, and if the two boards are gently closed, won't the book stand up steadily? Not only can it stand up, but it can also have the effect of shaping, keeping the pages flat and not wrinkled, killing two birds with one stone!

Tian Ling's thinking suddenly diverged, and he thought about the problem of classification and labeling, he used to think about pasting the number on the back of the book like a library, but it would be difficult to operate when encountering a thinner book, and the horizontal line bound books were not suitable for directly gluing the label on them like the plastic bound books in the library.

In this case, why not make a sign like the waist cards of the palace eunuchs and hang it on the book? Cut a thin piece of wood, write down the divided categories and content numbers when the time comes, and then string them together with a thin thread and clip them directly into the pages, which is simple and convenient, and there is no damage to the book!

When the shelves for storing books and classics can be directly made into the wide and narrow ones with splints and can be controlled by sliding left and right, I believe that this kind of shelf is just a piece of cake for Lord Song who can make cranes and bicycles.

However, it takes a lot of effort to classify the collection, according to the content of the book, by the title, or by the time and size of the calendar.

Tianling had thought about directly borrowing the classification method of the Chinese map method before, classifying the books and classics of the Tianzi Library, but after Tianling finished reading the four-story building, he directly gave up this idea, which is not as clear as the modern and various professional divisions, and the content of many books is not limited to a certain aspect, such as the local chronicles that talk about customs and human feelings, which may also be mixed with records of mountains, rivers, lakes and seas, and the books and classics from one to four floors, Tianling has almost never read it so far, and it is impossible to accurately determine which field each book belongs to. If you just flip through the pages and decide on the classification of a book, it is too unrigorous, this is not the style of the heavenly spirit.

If each book was to be carefully read and then classified, the Heavenly Spirit looked at the estimated number of books he had written down earlier, and felt that this idea would probably not be alive until a few decades later.

Categorizing by content is no longer possible, and similarly, there are limitations to the size of the use.

Calendar time is one way to go, but not every book has a clear provenance and date of origin, so this one is not good.

Then all that's left is the title classification!

If the book is classified by title, how should the number of the search be carried out? By initial? However, there are so many books in the Son of Heaven Library, and there are countless books with the same first word, if they are only numbered like this, when they are consulted as now, they are also looking for a needle in a haystack, then this book classification has no meaning at all.

Tianling paced left and right with his little short legs, how to solve this?

That's right! That's it! When the heavens are smart, they can learn from the dictionary!

Isn't the way to query the dictionary just a ready-made book title to look up the numbering teaching? The more Heavenly Spirit thought about it, the more feasible it felt.

······

In this way, a rudimentary library renovation plan gradually took shape in Tianling's mind.

"This plan is really bright and low-key!" Tianling nodded to himself, "If Your Majesty agrees, it will be much easier for me to find books in the future!" ”

After going through his thoughts from the beginning again, and after confirming that there were no major problems and loopholes, he started his second plan, the renovation plan of the Son of Heaven Library!

It's just that Tianling remembered it after he finished writing, he is now just a little boy on an errand in the library, and there is no way to meet the emperor at all, although he often has to send books to the emperor, but he only prepares the books and sends them to the palace where the emperor is located, and hands them over to Gonggong Hai.

And even if he met the emperor, if the emperor didn't ask him for questions, he wouldn't be able to open his mouth.

This damn feudal imperial power!

Tianling looked at the written plan in front of him, stupid!

Oh, it's written in vain?
