Location Scouting and Management Handbook
This is the only book I can find specifically on location management. There are books on production management, like
The Film Director's Team, but these focus exclusively on the jobs of UPM and first AD, so not much info on locations.
If and when you're in LA, it wouldn't hurt to call the Teamsters office, and ask for some contacts with working location managers. Make it clear that you're not looking for work (yet!). Offer to buy them a beer, coffee, whatever, and just talk to them about their jobs.
You might be able to to the same in NYC. I've never actually worked on a shoot in NYC, but I understand that locations in NYC can be particularly tough. I couldn't tell you if the union arrangement is the same, though the LA Teamster office could probably tell you how things work in NY.
As noted previously, Locations Manager is the correct title. A US TV show will typically have a
Location Manager, an Assistant LM, and hire locations PA's as needed. Location managers are represented by the Teamsters Hollywood local.

The area with the trailers for actors, hair, makeup, and wardrobe is always called
base camp. Choosing the location and arrangement for base camp is done through a consultation between the Locations Manager, the Unit Production Manager, the First Assistant Director, and the Transportation Captain.
The Unit Production Manager is the head of the assistant director team, usually in charge of all the financial and budget decisions for the actual physical production. If the production is large enough, the UPM may have a line producer above him who has the final say on budget issues. Sometimes, the UPM has the additional title of line producer. Unlike UPM's and first AD's, line producers aren't in the DGA. Line producers are above the line.
The first AD is the on set supervisor of all the personnel, budget and schedule issues. He reports to the UPM, but his primary job is helping the director get through the shoot on time and on budget. The first AD will always participate in drawing up the plan for location shoots, and raise any objections or advocate changes he believes are necessary.
The locations manager will do the primary legwork in terms of finding the locations, getting permits, securing property owners cooperation, renting facilities, hiring security and/or police, based on what's in the script and what the UPM, first AD, and Transportation Captain have told him will be needed.
The Transportation Captain is the head of the Teamster crew who drives all the trucks and vans, transports the trailers, rents and purchases vehicles for the production. He will advise the other members of the production team what he will need in terms of space, entrances and exits, travel routes, time and cost.
Locations managers and their PA's are the ones who put up those foamcore signs you see all over LA, wired to lampposts, directing the crew and cast to the location. They have to get there before everyone else, often at 3 or 4 in the morning to make sure that everything is clear to move in millions of dollars of people and equipment. Locations managers may end up staying on location after the shoot's over to clean up and tie up any loose ends.
