laddy,
You slowly map the library using the cabinet. Find which ones will will get you to more rooms until you have entered all of them.
You map, check all sides that has doors.
Keep notes. paths to make I found were 3. That covered all the rooms.
Remember that when you make a pattern, only 2 doors can be opened. Also to get them to opened, the button has to be green (red is closed).
