Research
In the research subsystem, PCs accumulate Research Points and learn new information or gain other benefits upon reaching specific thresholds. This subsystem is great for granting PCs more in-depth pieces of information as they continue to explore an area at large. Here, time passes in rounds spanning anywhere from 10 or so minutes to a full day. Each round, the characters use the Research exploration activity to gain Research Points (RP). As time passes and the party earns more RP, they gain knowledge and rewards, but also might face consequences or events. Some of these events might interrupt the round with a different kind of encounter (disrupting the Research activity), such as a social encounter with a lonely artificial intelligence or a combat encounter against a malfunctioning security robot.
Research challenges work best when the PCs face a time constraint, rival research group, or other form of external condition that presents additional pressures—if the PCs have all the time in the world to safely investigate a database or ruin, you can usually simplify things to a simple skill check since the PCs are free to keep rolling until they uncover everything there is to find.
Building a Research Challenge
Designing the Library
Throughout the library, you'll place research checks. These describe the task that the party is doing to Research—asking in a chat room, skimming books, chemically testing samples, or talking to a stubborn administrator—and a number of skills and DCs the party can use with the Research activity, in order from the lowest DC (the skill that works best) to the highest DC.
Designing the Stat Block
Reaching thresholds can also change the state of the library, in the PCs' favor or otherwise. In a poorly managed database, the first threshold might simply be cable management to help subsequent checks, but in a haunted database, necrolinked undead might appear to check their feeds. Reaching a research threshold can do just about anything, but it should have impact.
You don't need to evenly space thresholds—you could require very few Research Points for crucial clues you want to ensure the PCs receive and a much larger number to reach the final threshold that grants a special reward.
Published adventures use stat blocks like the one below.

Research Checks The checks PCs can attempt to conduct research listed alongside their locations, tagged with area codes or page references when appropriate.
Research Thresholds Each threshold lists the number of RP required to reach it, followed by the effects for meeting that threshold. Thresholds are listed in order from first (requiring the fewest RP) to last (the highest threshold).
