Kapow! Electronic Resources
Just back from a meeting about the Library's web site, which reminded me of the many electronic resources to which we subscribe, and that are available in the reading rooms at St Pancras, Colindale and Boston Spa.
There's a listing American-related resources here.
And one of my favourites? Underground & Independent Comics, Comix, and Graphic Novels.
Also, if you a British Library reader's pass, then you can access some resources, including some historical U.S. newspaper at https://eresources.remote.bl.uk.
