Some custom enchants work better the higher level they are (check List of Enchantments for maximun levels).

You can combine books of the same enchant and level using the /alchemist

Place 2 books of the same enchant and level into the top 2 boxes.

A new book will be combined, accepting the combined book costs XP, confirm by clicking the green box to recieve the higher level book.

Keep combining books - along with magic dusts until your books are 100% success.
