Information, technology, books, and help to build this site and gather the information.
See my blog post about getting started with this project [eventually will incorporated into this site]
The Meetup group MaptimeLA led me to the tools to make this site and provided help along the way. They also have worked on another historical restaurant mapping site Los Angeles resaurants.
Charles Perry, President of Culinary Historians of California. Charles also suggested I expand on his list of Croatian run restaurants, hence this website.
Los Angeles Public Library, History and Genealogy Department and on-line resources
Los Angeles City Archives
The website Chronicling America. US News Map—Searchable Newspaper Archives
Ancestry.com—People and City Directory Searching (pay)
Eterovich who wrote numerous articles about Croatians in the West

Stackoverflow and gis.stackexchange.com. Two related websites where people answer questions mostly related to implementing software. Searching on the site helped me many times and most of my questions were answered or got me pointed in the right direction.
Nick Gauthier's blog post, PostGIS and Rails: A Simple Approach. Got me started with PostGIS, a geographic add on to PostgreSQL. Although I now know I could have done this site without PostGIS, PostgreSQL alone can handle the geographic needs of this site.
The web building software Ruby on Rails for data driven sites. Makes it relatively easy to provide the complex links on many of these pages.

Regina O. Obe and Leo S. Hsu, PostGIS in Action, Second Edition. Trivia coincidence alert: the cover features a drawing of a woman in mid-nineteenth-century traditional clothing from Ubli, Croatia. Many of the restauranteurs covered here are from Brač about 50km away.
David Bryant Copeland, Rails, Angular, Postgres, and Bootstrap
Ruby on Rails,Postgres and the app for OSX, QGIS …
Numerous great gems, and the following diagram produced with the Rails ERD gem. At this writing some of the fields were for testing and trials and need to be removed. And "year" is usually shown as "connection" in most places.
