NEC editions

[infinity]

Does anyone have a list of all of the years (code editions) that NEC was published?

It's in the "history and development" of the NEC in the first few pages of any edition. The first was 1897-must have been kind of thin.

I glanced at the list but it contains things like these consecutive years:

1897, 1899, 1901, 1903, 1904, 1905, 1907, 1909, 1911, 1913, 1915, 1918, 1920, 1923, 1925, 1926, 1928,
1930, 1931, 1933, 1935, 1937, 1940, 1942, 1943, 1947, 1949, 1951, 1953, 1954, 1955, 1956, 1957,
1958, 1959, 1962, 1965, 1968, 1971, 1975, 1978, 1981, 1984, 1987, 1990, 1993, 1996, 1999, 2002,
2005, 2008, and 2011.

We're there separate editions for every year on the list? If so I'm assuming that not much changed from one year to the next.

Yes these are all separate editions. As you can see, the NEC has not always been on a 3 year cycle. As you noted, some years there was a new edition every year. But also note that there was a 1971 and then the next edition was 1975.

Not that I was around yet, but wasn't there lots of changes in the electrical world in the time period where there was a new code practically every year, maybe there was changes simply because of necessity from a lot evolving products and technology at that time.

Those older code books also were much simpler than those of the last 20-30 years and likely wasn't as big of a process to make changes.
