Transferring files over SSH

Generally, if you want to download, it will go:

scp user@remote_host:remote_file local_file

where local_file might actually be a directory to put the file you're copying in. To upload, it's the opposite:

scp local_file user@remote_host:remote_file

If you want to copy a whole directory, you will need -r. Think of scp as like cp, except you can specify a file with user@remote_host:file as well as just local files.
Edit: As noted in a comment, if the usernames on the local and remote hosts are the same, then the user can be omitted when specifying a remote file.

One bibliography from multiple .bib files

The correct way to load multiple bib files is to use

\bibliography{file1,file2}

Note the lack of space between the comma and the files!
