Electronic document type marking

For references to electronic literature types such as databases, computer programs and bulletin board system, the following letters are used as symbols:

Electronic bulletin of electronic reference database computer program

Electronic document type mark DBCPEB

For electronic documents with non-paper carriers, when they are cited as references, the carrier type should be indicated in the reference type tag at the same time, and the carrier type of electronic documents should be indicated by two letters:

Magnetic tape)-mt; ; Disk)-DK; ; CD-r om-CD； Online network (online)——OL.

Names of reference types, including file carrier types, are expressed in the following format:

[Electronic document type label/carrier type label], for example:

[db/ol]- online database online;

A database on tape.

[m/CD]- CD monograph

[CP/DK]- Disk software (computer program on disk)

Online log series

[EB/ol]- Online bulletin board system.

Traditional literature with paper as the carrier does not need to indicate the carrier type when it is cited as a reference.
