Very good. These are all important.
Oh yeah! Not only will the experience look good on your resume, you will get equally valuable letters of reference from your employers if you prove yourself. Experience and a good rep will take your further than anything else.
Welllll, use your best judgement here. Is your GPA the end-all-be-all that will make or break your career? No, but it’s not unimportant either. Get your grades as high as you can while still maintaining your extracurricular workload in volunteer/internship/part-time work. I’ve said it before and I’ll say it here: The things that will get your foot in the door are experience, letters of reference, and a reputation for working yourself to death and then working some more. Computer and other technical skills are also a bonus. That said, you won’t be doing yourself any favors by getting a 2.3 GPA.
There’s no easy answer here, Orual; it depends on so much. Where are you located right now? Are you willing to relocate across the country to find the job you seek? Is there a special kind of library you want to work in? Do you want a management job? These and any number of other factors will determine your outlook.
Absolutely, Orual, and from what I can see, it sounds like you’re off to a decent start. And since this is IMHO, I’ll share with you what I have seen work in the field.
Don’t worry too much about finding that special archive job right away. If you find a good job with bennies, take it and continue to work toward an archiving job. Keep auditing classes even after you get your masters. Consider a second masters degree in a separate field (A masters in history, for example, would probably be a good fit for archiving.). Network with other libraries, join the ALA, ACRL, and other professional organizations. If you don’t know computers already, either take workshops or teach yourself. You can’t have too many tech skills.
Above all, work. Work, work, work, work, workity work. Keep moving forward, keep striving, keep learning, keep your chin up. Something will come up, if not now than eventually. The path to your goals in libraries is rarely straight, from what I’ve seen, but the good news is that you are guaranteed to learn quite a bit.
Once again, it seems to me that you’re off to a good start. Keep up the good work, and let us know how it turns out.
