The table at the bottom of the search results page indicates where to obtain more information for the entries of interest. For records filmed by the Mormons, there will be microfilm numbers. For those in the Archives, there is a link to an order form to write to Poland for copies.
How you use the information in your research is a subject far too wide to handle here today. Instead, I’d like to offer some suggestions that might enable you to make good use of your time at the Family History Library. There are some interesting ways to interpret the indices in search results even before you look at the actual records and these ideas may help you uncover other surnames and records that you want to research and copy.
