A call number is the unique number given to each book in the library. Call numbers are like addresses, they tell you where a book will be located in the library.

105 --Read it numerically (1, 10, 100, 100.5, 105, 1005.10, etc.)
.K55 --Read alphabetically and then decimally (.A23, .A233, .A33, .B4555, .B50, etc.)
1981 --The final line is a date.
And here is how this book would be placed on the shelf:
