Here's a recent one (I didn't ask for permission to quote the letter, so I've blanked out some details from the original mail):
I saw your blog and wanted to ask you a question. I was wondering if it would be possible for me to get a job as a librarian in Singapore. I am [from country omitted] with a master's degree in library science and another master's in psychology. I am able to speak Chinese on an intermediate level.
Yes it's always possible. Check out the job listings at the Library Association of Singapore website: www.las.org.sg/jobs.htm
Speaking Chinese would help, but majority of Singaporeans speak English. It's our de facto working language. More info about Singapore, at: www.sg
In my reply, I forgot to add that anyone interested in library jobs in Singapore can also join the Librarians-In-Singapore mailing list. Questions about the Singapore library scene can be posted and answered there.
