Let's play with JSON to access the NARA Catalog Morgenthau Diaries Series:¶

- we use an API call where we specify a NARA Series ID directly: 589213¶

- API Call: https://catalog.archives.gov/api/v2/records/search?q=*&abbreviated=true&limit=200&title='Diaries'&naId=589213

NARA Catalog Hierarchy	JSON Structure for the Query of FDR Series 589213: "The Morgenthau Diaries"

- Using Python to talk to NARA's Catalog through API calls:¶

import requests
