Connecting concepts: references as guides and installing code libraries

While blogging about some programming work, I noticed a connection between two things.

The first thing is the concept of installing code libraries. Sometimes a programmer wants to use some existing functions and one way to do that is to install the relevant code library, giving him access to use its functions in his programming project.

The second thing is the concept of using references as a guide to doing some intellectual activity. I use many guides while doing my intellectual activities. Here's a guide I use for making blog posts.

How do they connect?

Keeping a guide in mind while doing an intellectual activity is analogous to installing a code library for a programming project.
