List the Book for Sale

Listing for sale is divided into two steps: minting the ebook and listing it. An analogy to traditional publishing is printing manuscripts into books and placing them on bookshelves for sale.

Step 1: Mint the ebook

Click "Mint Book" at the top right corner of the ISCN record.

The system will automatically redirect to the Liker Land Book Press website Mint Liker Land NFT Book page, and the ISCN ID will be pre-entered in the "Enter ISCN ID or NFT Class ID" field. After clicking "Sign In" at the bottom left corner to log in to the website, click "Submit".

Alternatively, go directly to the Liker Land Book Press website and click "Print New Book". Click "Sign In" at the bottom left corner to log in. Manually enter the previously registered ISCN ID in the "Enter ISCN ID or NFT Class ID" field and then click "Submit".

If you forget your ISCN ID, you can retrieve it in "My Works" at app.like.co.

The system will automatically extract the basic information of ISCN for you. Fill in other information required in the "By filling required information" tab.

Enter the number of NFTs to mint in the "Number of NFT to mint" field.
The system will automatically extract the link to the AR cover and place it in the "Image URL" column.
"External URL (optional)", "URI (optional)", and "Max number of supply for this NFT Class (optional)" can be filled in as needed.

After filling in and confirming that everything is correct, click "Mint".

The 🎉 Success! screen appears, indicating that the NFT has been successfully minted. Click "Continue to publish NFT Book" to complete the listing. Click "View your NFT" to view minted ebook in Liker Land.

Since it is not yet available for sale, you will see the words "Sold Out" on Liker Land.

Step 2: Book Listing

Return to Liker Land BookPress, click "Continue to publish NFT Book", and the NFT Bookstore Management Page will appear.

If you accidentally closed the page, you can enter your NFT Class ID in Step 1 "Enter ISCN ID or NFT Class ID", and you will see "Continue to publish NFT Book". The Class ID is the string after the URL of your ebook. For example, your NFT URL is https://liker.land/zh-Hant/nft/class/likenft1qq06n42guzvt087wxunaajvz3alx6wadq6mfz0yz57gffwsrgrasl2m59x, and the NFT Class ID is likenft1qq06n42guzvt087wxunaajvz3alx6wadq6mf z0yz57gffwsrgrasl2m59x.
