Bookishly is often used to describe something that has a literary or scholarly tone, but there are plenty of other words that could be used in its place. Words such as erudite, scholarly, intellectual, well-read, bookish, and learned all convey the same idea. Each of these words has its nuances, however. For example, bookish is generally used to describe a person who is excessively devoted to books and learning, while scholarly is more often used to describe a person who is knowledgeable in a certain field. Overall, though, any of these words could be used to replace bookishly in most contexts.
