You could also copy a passage out of one book, then write some other words, and copy a passage from another book and write some more and so on, and this was making a compendium. Compendia were also very useful. There are works that are lost but parts of them survived when they were quoted into other books that got to be more popular than the original. Maybe they copied the most interesting parts, and so people made a lot of copies of these, but they didn't bother copying the original because it wasn't interesting enough.
