Travel / Travel to Lomza [2]

I wish to travel to Lomza (OK I know the L is wrong) in July to do research for a book I am writing. I will need help since I don't speak Polish ... only English. I am interested in Lomza in the period between the wars (say 1915 to 1939) so I need someone who knows their history and can read old maps in Polish. Any ideas? Also, HOW do I get to Lomza, as there is no train?
