Book

Books are kind of a special note storage similar to envelopes. The goal of books is to give a secure way of lending sets of notes and organizing notes in locked bookcases.

They have the following capabilities:

possibility to reorder the notes inside
possibility to be bound (sealed) to prevent its further manipulation (like editing or taking things from inside)
possibility to use expensive binding
possibility to copy the whole book
possibility to go to the previous or next note in the book

Books are very similar to envelopes, so after you build one, you need to use envelope icon ("put this note into envelope") instead of storing in a storage. It also means you can use operations on multiple notes to facilitate the process. After you put notes inside, set the correct order and decide about the title, then you can permanently bind the book. It means the title becomes unalterable, all the notes inside become uneditable and impossible to take, but they still can be read or copied. It also becomes possible to copy the whole book, including the notes inside.

Books can be described using a bodkin, but book description needn't mention the title, as title is already visible.

To reclaim the notes from a book you can disassemble it using an axe.

Bookcases work well with books - it's still possible to read a book when it's in a locked bookcase.

The Reason for Books

What is the reason to have books? To answer this, it's necessary to consider what the main problems are regarding publishing and sharing notes using envelopes.

You can't show the contents of an envelope without risking somebody quietly taking/editing one of the notes inside. You have to check if everything's alright every time somebody gives you an envelope back. Another trouble is organizing them - when multiple notes represent consecutive parts of the same text, then it's hard to have them go one after another, especially after copying them.

How Are Books Used

Manufacture a book - a few options are available. The book is a note storage like an envelope, so in your inventory it's in the "Notes" category.
Put notes inside. Use the same button as for storing into an envelope.
Look in the book, click "reordering" and change the position of notes using drag and drop. Then confirm so that your changes are saved.
Bind a book (a special button). Select the book title and confirm. Then it's impossible to put more notes inside, take, edit or reorder them.
Click the "copy" button to start copying the book project. It creates a book with the same type of binding as the original book.
Click the X button to start disassembling a book. It results in destroying the book and getting the notes back.

Books don't provide any built-in visual template to make notes look like a book. That's something that can already be done well with CSS. This feature is to facilitate the use of large note storages and the management of libraries.
