I'm a biochemistry major (with minors in psychology and sociology, but I'm not sure how relevant that is) about to start on my graduate school applications. This past school year, after a lot of thinking, soul searching, and research I've come to the conclusion that I want to become a librarian at a university library, preferably specializing in biological sciences. I've researched MLIS programs and have a good idea of where I want to apply. Recently, I began looking at job listings in the field I want to work in. I've found that most all of the listings either require or desire a secondary masters in a science related field.
I've enjoyed my undergraduate studies in biochemistry and will have have participated in laboratory research since I was a freshman. However, the major factor that led me to realizing that I want to become a librarian and not a "scientist" was that while I enjoy learning and reading about science, lab work isn't something that I particularly like doing. I've worked in several different labs, so I'm confident that it is lab work in general that I'm ambivalent about, not merely the topic or PI. However, if a masters in a science subject is required for the type of job I want, I'm willing to do that.
I guess my question is, would it be better to first go for a masters in biology, genetics, or a related program, or head straight to my MLIS and try my luck at landing a job without the secondary masters before working on an MS? And would it be unheard of to get the MS from a university where I was working as a librarian? To me that would be the best scenario, but I have no idea if that would even be a possibility!
