which kind of books you want and their intended form of reading
how often you will want to search the contents
how often you might want to refer to the contents when applicable, such as reference books
whether you have the urge to press ctrl+f whenever you want to find something in a long text
how likely you are to immediately look up the definition of a word (perhaps in another tab or window) as opposed to just keep on reading and infer from context
other stuff that’s easier to do when you’ve already got the text in electronic format and have direct access to search and lookup tools
