First I'll describe what I'm looking for, then you can read on to understand why.
There exists a document published by LAUSD, or its predecessor in about 1955 which lists all the schools in the system to date, including defunct ones. I have seen this myself in person, and I thought I had seen it online as well, but I have been unable to find it since. What I am asking for is that anyone who can get at a copy of it, look up the two schools named below and tell me when they were founded and discontinued. I think LAPL Central may have it, or UCLA--probably in YRL.
I've been trying to research the history of two public schools, long since defunct, which were located next door to each other and had almost identical names. Both schools were in that peculiar odd-shaped block bounded by Bauchet, Avila, Clara, and Vignes, just northeast of Union Station.
Macy Street School, founded about 1885. The address today would be around 910 or 908 Avila, but in the early years of the 20th century was in the 700s.
New Macy Street School, founded about 1895 at the NE (and only) corner of Avila and Clara. Today the replacement schoolhouse, built in 1915, still stands and has been home to various private sector businesses, including Aladdin Bail Bonds, for many years. You might think the name "New Macy Street" arose from a misunderstanding and that it was merely intended to be a "New" building to replace "Old" Macy Street School, but you would be incorrect. Clara Street, running between Avila and Vignes, was known briefly as New Macy Street in the 1890s. In a 1902 map it had become Garibaldi Street, and by 1906 it appeared as Clara Street on the Sanborn from that year. Following the usual LAUSD practice, the original name of the school was kept regardless.
The New Macy Street School building today:

I could never figure out why this building looked so unusual as compared to other small commercial buildings, and then when I learned it had originally been a school it all made sense. The numerous large windows almost give it away by themselves, but also the arched windows and slightly classical touches were typical of schoolhouses built in the 1910s.
In attempting to research these schools, I have been unable to separate them from each other. Early 20th Century city directories usually didn't give street addresses for large public institutions, but simply say something like "Corner Avila and Macy", which could conceivably apply to either school. Where house numbers are given they are not much help, because this street was renumbered sometime in the early 20th century. This was many years after the early 1890s renumbering project that eliminated most one- and two-digit house numbers from the city limits. The old numbers along Avila were in the 700s, and today they are in the 900s.
