i will forgive you guys since you don't know my wife but i am married to a reference librarian in a public library and she is all right by me.
thankless work. they are completely at the mercy of the public----they have to humor the most inane questions from all directions, from medical advice to "what is chili"? also, if you happen to work at an underfunded/inner-city library, you also double as security. having to regulate addicts nodding off as they surf porn sites, to helping illiterates navigate job applications, it can be pretty harrowing.
sadly, libraries have to take up the slack from a city's lack of social services. kids with absentee parents, the homeless, the drug addled, the unemployed, etc, have nowhere else to go.
most of the librarians i have had contact with are very eager to help you if you have a focused question----they seem to be relieved you aren't asking them to, say, make you copies of key lime pie postcards issued between 1978 to 1987 for your child's overdue homework assignment.
