In order to define what is an e-journal, as well as to define any other kind of tangible or intangible object, it is to understand the form of it. First of all, it is to be said that neither the form, nor the card bin of e-journals can be compared to the paper journal every one knows. The paper journal item division doesn't exist in the database, that collects and organizes the full-texts. Actually, the full-texts are available in an easier way than the physical bookcase access (item/volume/year). This is the difference between the physical card index and the OPAC (Online Public Access Catalogue) access.
