I would say that jobs are actually quite good in the field, but then that really depends on where you went to school and also, what area you are in. To give you a bit of background, I have worked as a public librarian and a university librarian in the reference capacity. The field of young adult services is quite good too and, as a plus, it is quite fun.
Per the Atlanta post, have you been in a library recently? Sorry, but I am afraid that a simple look at the staff certifies that there is more or less no one over 25 within the library. But then again, that is just me. One should also note that going to a top 25 school really helps out a great deal. Also, make sure to go to your states conference and do some networking to see if this is what you want to do.
Many people go into the field with a notion that they will be reading all the time and surrounded by literature. This is just not the case. In fact, you might have very little time to read as a librarian. So make sure you understand WHAT the field is about (i.e. information, not just books) versus whatever outside conceptions you might have coming in.
Do not, go to a non-ALA school, and if possible, go to a top ranked one. U.S. News does these rankings and they are free online.
