But I end up writing books full of notes this way.

Don't, faggot. Read at a comfortable place and try to actually comprehend what you're reading, speedreading is a meme. Take notes for long-term retention.

Well, then trim them down. Use abbreviations, aim for 2-3 lines per paragraph, cut out the unnecessary shit.

Eat the textbook to digest the knowledge.

Write notes while you read.
Shortly afterwards, review your notes and summarise.
Keep the summary, archive the notes.
This helps confirm that you've grasped the key points, and gives you something useful for revision later.
