According to the carrier form, what kinds of references can be divided into?

References can be divided into paper type, miniature type and electronic type according to the carrier form.

1, paper type

A document that records information on paper by writing, printing and printing. It is a traditional file form, which is easy to read and circulate, but it has a small storage density and a large volume, which is not convenient for management and long-term preservation.

2. Miniaturization

It is a form of information produced by microfilm or plain film as the carrier and microfilm technology as the recording means. A holographic film can store 200,000 pages of literature. Its advantages are small size, high storage density, long storage period and easy collection and management. The disadvantage is that you have to read with a micro reader.

3. Electronic type

Books that are based on magnetic or optical materials and need to be read by computers. In other words, e-books refer to the mass media that store pictures, texts, sounds, images and other information in the form of digital codes in magnetic, optical and dielectric media and use them through computers or similar devices.
