# Bring a source
> Keep a primary source in Library so you can use it now and reread it in a future task.
AI Now · Lesson 2 / 5 \~5 min Intermediate
Question
Source
Evidence
Investigate
Save
Add one primary source to the AI Now task in Nowledge Mem. Use its exact wording to check the question you scoped in lesson 1.
## What you'll accomplish
You'll keep one source in Library and verify that AI Now can read it alongside your saved knowledge.
## Learn with the simulation
On desktop, the simulation opens automatically when you enter this lesson. Follow the popup hints to send a request, read its reply, and check the result. If you close it, click **Start the simulation** under [Your turn](#your-turn) to reopen it. Each lesson prepares its fictional Atlas materials; no model setup is needed.
The simulation runs locally with preset replies. It does not call AI or search the web, and refreshing resets the practice. On mobile, read the steps first and use a desktop browser for the interactive exercise.
## Before practising in the real app
Continue the lesson 1 conversation with its checked context summary. Choose a source you can use with your configured AI provider.
## Your turn
Follow the hints in the automatically opened simulation. After practising, use the steps below to repeat the workflow with your own material in Nowledge Mem.
Use interview notes, a retrospective, or another document directly relevant to the question. For the practice task, save the following as `atlas-planning-interviews.md` in a text editor:
```markdown theme={null}
# Atlas planning interviews — fictional practice material
These notes are invented for this course, not real customer evidence.
## Interview A — dependency visibility
A team noticed a shared dependency only after committing to its quarterly plan.
The interviewee wants teams to compare plans for the next twelve months before committing.
## Interview B — preparation burden
Teams already write quarterly review notes.
The interviewee would try a joint review if those notes could be reused,
but does not want a second reporting process.
## Interview C — unanswered question
This team has not tested a cross-team review of dependencies over the next twelve months.
These interviews contain no measurement of time saved or dependencies avoided.
```
Import the file into **Library** in the same Space as your task memories. Wait until it is **Searchable**, then return to the lesson 1 conversation and refer to its exact name. If it is already there, use the existing document. You do not need to extract memories to read it.
Continue the Atlas task with a specific instruction:
```text theme={null}
Find and read atlas-planning-interviews.md in Library alongside the Atlas planning memories already found. First identify the document and its sections. Then list statements relevant to holding one cross-team planning review of the next twelve months, citing the interview heading for each. Separate what the notes say from your interpretation. Use only these sources; if you cannot read the file, say so.
```
Open the file and compare a cited passage with the answer. In the practice material, Interview B allows a trial only if existing notes can be reused. It does not support adding more reporting.
Follow the popup hints; reopen the simulation if you closed it.
Lesson complete. Continue to the next lesson, or try it in Nowledge Mem.
## What you should see
The source is Searchable in Library, and AI Now identifies the correct document and sections. You can trace one finding to its passage, including the condition attached to it.
You can also attach a file directly to an AI Now conversation for analysis. This course uses **Library** so a fresh task can find the original later. A file name in a saved memory does not prove that the original can be reopened. If AI Now cannot read it, check the document's Space and indexing status before continuing.
## Why this matters
A primary source gives the task evidence. It lets you distinguish what the material says from what you or the AI infer from it.
