Plan for productive downtime
You may find that you have some downtime between assignments. Have a plan to use it productively! Perhaps you can use it to check out some of the professional literature recommended by your summer colleagues, work on a BWEXIS certification, start digging for ideas for a fall note/comment, etc.
Get to know your new coworkers, both attorneys and staff
You will receive help with your research from your fellow attorneys or summer interns. Quite likely, you will also be helped by others on the staff, like paralegals, secretaries, and librarian. It behooves you to foster good lines of communication with all your summer co-workers. Do not be the snarky, demanding or ungrateful summer intern who fails to get a job offer. Be yourself!
Dot the ‘i’s and cross the ‘t’s
When you think you are done – make sure that your research is up-to-date. Make sure that any primary law is still good law. If using printed resources, check the dates of the last update / pocket part or supplement to see if further updating may be needed.
