Webpage I'm building
Right here. It's devoted to the legislative history of the Firearm Owners Protection Act of 1986, which extensively rewrote the Gun Control Act. A big problem is that researching the history of FOPA is almost impossible. Almost all of it is pre-digital. The standard first resource, US Code, Congressional, and Admin News, is hopeless -- it tells you there was no Senate committee report, and gives you, without explanation, a House committee report that doesn't describe what was enacted.
My aim is to present a reasonably complete legislative history, both in key word searchable text and in pdf scans (in case they are needed as exhibits in court). I've got the committee reports, a background report, and the House floor debates, plus some on S.2414, which modified the interstate travel section of the legislation. I've still got to scan and edit the Senate floor debates.
