The database was at first stored on punched cards. The Encyclopedia contains the references to the corresponding sequences (which can differ of their few initial phrases) in A Handbook of Integer Sequences as N-numbers from N0001 to N2372 (as a substitute of 1 to 2372.) The Encyclopedia includes the A-numbers which might be used within the OEIS, whereas the Handbook did not. These books have been well obtained and, particularly after the second publication, mathematicians provided Sloane with a steady flow of new sequences.
