This year, Inauguration Day will take place on Friday, January 20th. The Law Center — including the Law Library — will be closed. The Law Library reference desks in Wolff and Williams will close at 5pm the day before (Thursday, January 19th). Regular hours will resume Saturday, January 21st.
The details of the secure zone have not yet been released. In previous years, the zone has covered about 1.5 miles from K Street and Massachusetts Avenue NW on the north to Independence Avenue NE & NW on the south, and 2nd Street NE on the east to 23rd Street NW on the west. To be allowed into this area you must have and show current Law Center identification at security checkpoints.
For newcomers to DC, this Guide to the 2017 Presidential Inauguration provides some information about additional closures (e.g., Metro stations). Many locals will be staying home to avoid the commotion, which is expected to continue at least until the next day when the Women’s March on Washington will take place.
