I believe that everyone has had such a situation in life: when we read more books, we will take more and more notes. However, when we want to quote a certain point in a book or think of a book and reread the reading notes of a book, we can't remember which notebook the reading notes about this point or this book are written in. If we look for them one by one, we will only waste energy and time.

So we need to make a catalog retrieval label after taking reading notes. The following methods can not only help you find out the books you read ten years ago, but also remind you of what you felt when you were reading.

Fortunately, we live in this great information age. When we make catalog retrieval labels, we don't need to make them out of paper or bamboo like the ancients. This method is laborious and difficult to find.

We can use computers to make index data of reading notes. If you use a computer, even if there are 1 thousand titles in the data, you can find them immediately by clicking on "books with the word' finance' in their titles". Of course, for those who read less, it may be enough to use the cover of a notebook to make index materials and browse for them; But for people who read a lot, this retrieval method is perfect.

so how to use the computer to make index data of reading notes?

index reading notes in documents. By doing so, you can find the notes you want to refer to by reading the date.

The author of How to Read a Book Effectively, Hiroyuki Ono, made the index data of reading notes in this way:

When inputting the index data in the notebook, Hiroyuki Ono compiled about 2 notes into hundreds of lines in the following format:

The input information is six items in turn: notebook number, reading date, note type, title, author and publisher. The last line, for example, means "The page on September 5, 213 of the 19th Note is a reading note, and the target book is" Black Heart Enterprise ".

We are often interested in books in a certain field at a certain stage, and unconsciously read many related books.

according to the interest in a certain thing or theory at that time, we can also set keywords when making index materials for reading notes, such as red wine, weight loss, pets, drama, computer, etc., and such as Italy, Kyoto and Taisho Times are also good starting points.

The production format can be as follows: the words in

are the key words. The purpose of this is that when you want to write an article on a certain topic but can't find a breakthrough point or material, you can get reference materials at one stroke by searching keywords, for example, when searching the word "media" in the index, you can get a list mainly based on media or publishing related books.

the method mentioned above is applicable to the case of handwritten reading notes.

In the actual study, I also made an index directory, but my reading notes were not handwritten, but made in word documents. I referred to the format of each note document name, such as

Then I set up a folder for storing reading notes on my computer, and classified them. When I want to read the reading notes of a book, I will search in the general folder with keywords or titles, and pass the search.

Therefore, when studying, we should not only make reading notes, but also make index materials of reading notes, so as to get twice the result with half the effort.
