He feels an open summons and lets it grab him -
"So it would seem. Anyway, you're probably going to sleep soon and I don't mean to keep you up. Can you direct me to the library or be extremely specific about how I might identify some specific local map so I can find it myself?"
"Out the front gate of the graveyard, turn left, keep going, turn right on the helpfully named 'Main Street', it's the building with the big sign out front that says 'Sunnydale Public Library'. If you go out the wrong gate you'll find that the graveyards you pass are noticeably more run-down the farther you go; retrace your steps and try again."
Cam heads up for the crypt exit, coat-clad, and is conscientious about not letting too much sunshine in.
Cam made this coat with plenty of pockets he could obtain things "from". He looks at the date on a page-a-day calendar behind the circulation desk and the time on a clock on the wall, makes a correctly-set watch with these and other functions, takes it out of a pocket, and puts it on. Then he goes up to the help desk. "Excuse me. Does this library have a way for me to use the internet with my own computer or do I need to use a public one?"
Well, sort of in use. Mostly in a condition of being glared at and hesitantly prodded.
Cam picks a different one and looks for whatever pathetic excuse for a browser is on these things.
Judging by his posture, the other computer user in the room has just given up completely.
Cam grumbles but opens Internet Explorer. He has to concentrate not to lash his tail more than once. It's so lashable.
...He shakes his head distractedly and goes back to his apparently very incompetent computer use.
Cam's not all that much better. He's used computers like this before, but he kept up with the times, so it's been literally more than a hundred years. He pokes his way to Wikipedia, pauses to attempt to remove dust from the mouse, and starts looking up various historical events. Then he looks for anything so promising as a USB drive on this device; maybe he can conjure up a... ludicrously condensed version of his notes to compare against. His current computer model is sure not going to pass without notice here.
The frustrated computer user gives up again, and this time he walks away to go look at books.
A floppy drive. Holy shit, this library is terrible. It's supposed to be 2008, he was what, past twenty in 2008, he doesn't remember being out of his teenage years and using fucking floppy disks. Maybe he'll just see if Sherlock wants to pack up and travel to a halfway decent city. Well, at least this device can get him Wikipedia. Sloooooooowly. Is the Earth the right size and shape and location? Yes. Is China where it belongs? Do kangaroos exist? Is Coca-Cola popular? Yep. Wikipedia, how Cam loves you.
Did the Revolutionary War happen circa 1776? Did Pol Pot kill a shit-ton of people? Are there weird rumors about the Bermuda Triangle? Yes and yes and yes.
Cam will be at this for a while, keeping an eye out for discrepancies.
