We have Leadville city directories from 1879-1918 (no city directories were done in 1893 or 1896). The city directories list residents (head of household) in alphabetical order with residence and often place of employment. Women usually are not listed unless they were widowed or owned a business.
Looking for beyond 1918?
From 1919 to current we have phone books that are currently not accessible to researchers due to the closure of the Leadville Room. The phone books from 1919-1955 are poor photocopies, and there are some pages missing, but they can still be useful. If you need any research done in the phone books, please send your request to firstname.lastname@example.org.
The city directories are available as downloadable PDF files using this link. Each PDF will need to be searched individually. Once you have opened one of the PDFs, you can perform a search using Control+F on your keyboard, or go to Edit>Find. In the little search box you can type the address in, and it will bring up results if it can find them. Sometimes the optical recognition has issues and won't return any results, which means going through line by line and page by page to see if you can locate the address visually.
Sometimes searching the house number (for example, 318) and using the next/previous buttons to go through the results can help you find the address if optical recognition doesn't return results. If you type a name in and no results turn up, you can scroll through the document or use the bookmarks to go to the letter you need (at this time most but not all have bookmarks).
Searching for the 318 W. 4th address in the Leadville City Directories provided an overwhelming amount of results. The earliest entry was in 1882, and the last was in 1918. Below is the list of names found in the city directories. If you would like to look at the corresponding city directory pages, it can be downloaded as a PDF document here.
