I wondered if the relatively new "Browse" function would work in this collection, and I wondered what directories, if any, were added for San Diego City and County. I went to the City Directories collection page, and saw:
Yes, they do have the "Browse" function operational for this collection. I selected "California" as the state in the screen above and selected "San Diego" from the city list in the screen below:
For "San Diego," the "Choose..." box showed city directories available for 1897-1901, 1936, 1937, 1938, 19040, 1942, 1943, 1944-1945 and 1947-1948, 1947-1948, 1959 and 1975. I don't recall seeing 1959 on that list previously, so I selected it from the list:
When I clicked on that link, the first page (of 2,194 pages) opened for my perusal:
I could then "browse" one page at a time through this collection, or I could input an image number (not a page number of the directory!) to advance in the book until I found the surname or street I want to find. There didn't appear to be a way to "search" in this "browse" mode - if there is, I would love to know how to do it!
If I wanted to narrow the search to only one year, or a range of years, I could have entered a year in the Year field, and added a range of years. I didn't do that for this search, but that is how a researcher would narrow a search to a specific year if they desired.
There were ten matches for "Seaver" from the 1959 Directory, and I finally found the right link for the alphabetical listing (on page 904 of the Directory, but image 1144 of the digitized pages):
There are three Seaver families in the Alphabetical portion of this Directory, including my parents Seaver, Fredk W. (Betty C.) a dist[rict] ag[en]t [for] Prudential Ins[urance] h[ome at] 2119 30th [St.].
Here I can see the telephone number that my family had - it was AT 1-4182 (it was the same backwards and forwards!). I can also see the neighbors on both sides of 30th Street. To see neighbors on Fern Street or another street, I have to go back to search for them or put image numbers in the search box to find them.
