How can I approach collecting specific storylines or events within the DC Universe?

To collect specific DC storylines or events, the first step is to identify the core titles involved in that event. Many major DC events have tie-in issues that are part of the narrative. Researching checklists or reading order guides for events like 'Crisis on Infinite Earths,' 'Infinite Crisis,' 'Blackest Night,' or 'Flashpoint' is essential. You can then focus on acquiring the main series and relevant tie-in issues, often collecting them in chronological order to best experience the story's progression.
