This JWebbinar demonstrates how to search the MAST archive for JWST data. We cover the features of the Portal Interface, customizable programmatic searches through two Jupyter Notebooks, and talk about creating DOIs (as requested by the mission) to promote reproducibility and increase your citation count. We do this in three mini-sessions where you follow along. Each session is followed by dedicated time for Q&A:

• We start with a brief overview of the Archive itself, then explore the features of the MAST Portal user interface, including basic/advanced search and subscription notifications. (~30 mins.)
• Next, we look at two Jupyter Notebooks: one analyzing exoplanet spectra, and the other looking at sources in a crowded field to retrieve the products you need to extract your own spectra. (~40 mins.)
• We close the session by going over DOIs; MAST offers a convenient way to create custom DOIs that permanently link to the raw data you used in your analysis. (~20 mins.)

An additional session was held on September 22, 2022.
