Why we need personal knowledge libraries?

Our ability to create and communicate is leveraged by the easy access to information. We can be helped in this by using Personal Knowledge Libraries. How this is possible? By summarizing and then and indexing information by keywords together with the most relevant summaries. This is very much similar to the way we accessed information using the back-of-the-book index except that now we can do it without the physical limits of a book. Also, our digital index has not hard limits in terms of size and content so it can be easily grown and customized to our many and diverse needs and interests.
