I know that there has been a lot of speculation about the phone numbers that don't have area codes, particularly 688-7092 with "Library" written next to it, since there is a library in Pennsylvania with this number. I think this is probably just a coincidence and that the numbers (at least the cluster towards the top of the page) written without area codes are all area code 213.
It sounds like (
https://en.wikipedia.org/wiki/Area_code_213) 213 is the 'original' LA area code, which might be why it didn't warrant an area code written before it, while the 818 area code had only been around since 1984 and only covered the San Fernando and San Gabriel Valleys. I think that she was in or very familiar with phone numbers and locations in the part of LA using the 213 area code, hence the Ben Perkins Jr. Law Office # not requiring 213 before it, even though we know that this location was in the 213 area code.
All of the numbers scrawled in the top portion of the page either have 818 written before them, or can be traced as having been valid 213 area code numbers in the 80's or early 90's. I found these results when I searched for the numbers with 213 in front of them in a Google Books search. I couldn't view the full books, but the results seem very relevant:

^ This # indeed had Pacific Bell Adm offices written above it so seems pretty solid that it belongs with the 213 area code, lending credibility to my thoughts below...

^ The book is a directory of advertising agencies from 1990. Although I frustratingly can't view the rest of this result, looking up that # now it is the fax number of Castells & Asociados, a Hispanic advertising agency based in LA:

This # has caused a lot more confusion because the number actually belongs to a Library in Pennsylvania. However, I think the note "Library" has been taken a bit too literally. A library isn't necessarily a bricks-and-mortar place loaning out books - it could be a library of images or information kept by a business or organization; i.e. I've held a series of marketing-related jobs (similar to the kind of thing on Lori's resume - that resume REALLY hits home, although I like to think of myself as an okay speller
) where I am responsible for maintaining libraries of photography and other marketing imagery for media inquiries, advertising, awards submissions and so forth. Given that she worked in this type of role as Lori Erica Kennedy it is not unrealistic to suppose she may have been doing something related in her previous life.
I don't know that the number belonged to this same advertising agency in the late 80's, but as of that Google Books result it was the fax number of some kind of marketing agency at that time. Perhaps she was faxing them a resume to apply for a job managing their image library, or faxing them photos or other information for their media library, or something along those lines?
This is a lot of speculation that may go nowhere, but my main point is that I think this further suggests she was living/working/physically going about her business in L.A. in the late eighties, and that the PA library is a red herring.
