Tustin Area Historical Society
50 years of Tustin News is available online for your enjoyment and discovery - for free! Thanks to an effort by the Tustin Area Historical Society and UC Riverside a few years ago, all of the hardcopy issues we had in our collection of our long-time local paper were "digitized" - meaning you can do some searching of the content and even create pdfs of pages and then print them. (That was over 2300 copies starting back in 1922!)
You will need to register for a free account to create pdfs. If you become a "premium user" with a donation of $25 to support their work, you have access to high-resolution images of the scans and you can save articles to a private list.
The user interface to search and move around (and zoom in) the pages takes a little getting used to - it's not as "user-friendly" as we may expect, but with a little patience, you'll understand all the functionality. (They do offer some help tips.)
