Share bibliographies on disk with others . Professors can distribute databases on disk rather than printed bibliographies. Import from library catalogs, CD-ROMs and online services . The bibliographic database manager can read the records into your personal bibliographic database. This saves a lot of typing time and ensures accurate references.
Most databases are too big to fit entirely in memory.
Individual records are retrieved into memory as required. This differs from a word processor, which treats your whole document as one large unit, which is often held entirely in memory. The same amount of disk space is used regardless of the amount of information actually put in a field. This is fine for small items such as names, address or inventories. Speed in finding records, since the position of a record is a simple multiple of the record length.
