# Page 378 - Dictionaries
In the next edition, I will add a note at the bottom of this section to set an expectation that readers will come across dictionaries again later in the book in more practical ways.
> Note: In Chapter 11, LINQ, you will learn how to create dictionaries and lookups from existing data sources like tables in a database using LINQ methods like `ToDictionary` and `ToLookup`. This is a much more common use than manually adding items to a dictionary as shown in this section.
