With all the reference material out there all the members have access to. We could start our own library.
Museums mostly. I am fortunate to be able to travel on business so I usually visit them whenever possible.
I do use web information but I always try and cross check it as I have been led astray in the past by some sites … (Never this one though!)
Books, when I can find those that cover my subjects.
Magazines like FSM and Ship in Scale.
A. Magazines (FSM & Scale Aircraft Modeler International are my two favorites)
B. Monograms ( …In Action, …Walk around, Profiles etc)
C. Internet
D. Flight (or Operators) and Maintenance Manuals
E. You guys
By the way, what does the 150HS have for a power plant? - when I learned how to fly, my instructer and I got into a 150, we had to unload 5 gallons of fuel to get under max gross weight.
Books and magazines are my favorite sources but the web has it all! Just look at this one forum, FSM. Tons of useful info just for the asking. [:)]
One of my favorite online research sources, “It’s All About Warfare” has closed down 
I do rely heavily on my books as well…as well as you guys 
Books and mags, books and mags…
I love the NASM at the Smithsonian just a few minutes away and soon we will have the new annex opening at Dulles Airport only ten minutes away.[bow] Having a friend who works at the Garber facility has been helpful in getting close to the subjects not on display. The Aberdeen proving grounds are only a day trip away and that is great for researching armor. I take dozens of rolls of pics at the annual Andrews AFB air show. Too bad they don’t let people as close to the aircraft as they did before 9/11. I am a chaplain in the Confederate Air Force and they have an impressive collection of WWII aircraft.[:D] I try to see the real thing if it is possible. Whenever I travel, I look for the nearest base or museum or any place that has displays. Puget sound was a good place for WWII ships in their mothball fleet. Other than that I look in cyber space[alien][^][:D]
Mags,books, documentaries, the WEB, and my most trusted, the Veterans and actual pieces, if I can.
I don’t think I’ve ever been to that site. Out of curiousity, why did they close down?
I am not sure David…I only went to the site when I needed a picture or some information as the site owner butch2k seemed to have more books than anyone else I know. His last post is here…but I was never a regular reader at the site so I don’t know what happened:

It was a great site as it had categories for Land, Air, and Sea for every major era in history-- including WWI, WWII, and the Modern Jet era…truly a great resource that I hope someone will try to revive.
Books mostly, I am building quite a library. The net is used more and more though, sites like ARC and hyperscale are pretty usefull, This forum is a good source of info too, there is always someone out there that knows that little thing you’ve been searching for.
I now only buy mags that have at least a couple of articles I know I’ll want again in the future, used to by FSM and SAM, SAMI etc all the time, but I was getting far to many, so these days I’m more selective.
FSM’s, Osprey New Vanguard books, Squadron books, Tony Greenland’s Panzer Modelling Masterclass book, and of course the many members contributions to the forum.
