Baseball Savant.

Baseball fans will want to bookmark MLB’s information-packed website for every imaginable baseball statistic. The data is powered by the Statcast tracking system, which uses cameras and radar to analyze every play and collect detailed information on pitch velocity, spin rates, swing rates, catch probabilities, and more. The search page allows users to query the database on a per-pitch, per-game, per-player, per-team, and per-season basis. Returned results include video clips, allowing users to see the plays in action.

Ithy.

This AI research platform synthesizes answers from leading AIs and large language models, including OpenAI, Google Gemini, ChatGPT, and Perplexity, to provide structured, article-quality responses. It is a super-tool geared toward students and researchers seeking more accurate and nuanced AI-powered answers. Responses are appealingly organized and accompanied, when available, by charts, images, and videos. The site offers two research modes—Fast Research, which returns more succinct results quickly, and Deep Research, which is optimized for complex tasks and provides in-depth reports.

The Kansas City Star Photo Archives. 

Through a collaboration between the Kansas City Public Library and the Kansas City Star, researchers can access a digitized collection of over 500,000 historical photos from the newspaper’s physical photo library, dating between 1920 and 1999. Many of the images center on Kansas City and the surrounding area, but others offer a visual history of people, places, customs, entertainment, and sports at the national or even international level. The collection is fully searchable and browsable through keyword-searching, image tiles, and curated topic lists.

Notebook LM. 

Geared toward students and researchers, Google’s AI-powered research assistant works with user-uploaded documents as its knowledge base, thus reducing hallucinations and grounding answers with citations and traceable sources. Users can upload up to 50 sources (PDFs, websites, audio files, slides) into notebooks, which then serve as the basis for future queries. The resource can be employed to create study guides, flashcards, quizzes, and outlines, as well as multimedia-based content such as slide decks and mind maps.

World Radio History. 

This comprehensive archive covering the history of radio, television, and broadcasting from 1900 to 2020 is a treasure trove for music fans and media historians. Created by former broadcaster David Gleason, the site provides access to over 140,000 industry trade magazines (including Broadcasting and Billboard), catalogs, hobby publications, company journals, and gray literature (logs and lists, registers, call-letter origins). Available as full-color PDFs, all materials are fully indexed and searchable.
