1) In the lecture we discussed using filters in order to parse through large amounts of data, is there anyway we can filter through the different types of truss bridges?
2) In the lecture we discussed e-books, does the drexel online e-book database hold all hard copy books in e-book form?
3) If i wanted to quickly sort if a source is scholarly or not, what are the tell tale signs of doing so, in a quick and precise manner with only look at the documents details and not previewing it?
