I don't know how many books I just discovered! Many ! I'd known of some digital libraries-I have several aleady book-marked. But pal,Jeanne Barton had sent me an url [web address] of the U.Pittsburg's digital library to research French and Indian war times. And the url did not work,in any combo I could try. So,I went to my favorite search engine,which right now is www.google.com and ,in quotes l like I use to search a name like "JOHN DOE" ,I typed " digital library" and had a mass of hits. Digital libraries are all over the place. I've come to prefer digital works to normal works because of search engines. I have a little shareware search engine on my own hard drive called 'BOOL.exe".I'm sure there are many,and no,I don't remember where I found it,on-line 4-5 years ago. But I love to research with it. I'm not limited by the index the author of the work prepared. Search for unusual 1st names, or locations, or dates, or whatever. And quickly. I do the same at on-line libraries like www.ancestry.com. Their search engine form may have blanks labeled 1st name and last name, but I might type FORT for 1st name and PITT for last name. Or LOCH for 1st name,and NESS for last name, or ship Welcome, or BULL RUN,or Marlboro furnace. Experiment. Genealogists,on www.google.com and likely more,type a surname DOE and add the word genealogy. Search for DOE genealogy,or SIMMONS genealogy,AND,OF THE HITS, CLICK ON DOE FAMILY FORUM, or simmons family forum .
