Thanks mike, that helps as I didn't have several of the 2009-2011 years. I have everything from 2012 and onward. Still trying to score stuff from 2008 and back to around 2000.
Up until very recently 2000 through 2008, including K-Line by Lionel were still on the server, but not accessible by navigation from within the site. Several of us found them using advanced Google Search, which returned outside links to them. On the other hand these weren't PDF's but pseudo-catalogs that had the complete roster that you would find in the catalogs, but in web page form. So each "catalog" was actually a collection of web pages.
These probably wouldn't help because they weren't actual catalog pages. If however you wanted to know precisely what was in the corresponding paper catalog they might be sufficient.
For instance here's a screenshot of the Table of Contents web page from the 2000 Volume 2 pseudo-catalog. You used to be able to use this to navigate to individual pages for each of the cataloged products:
And here's a sample product page from 2008 Vol 1:
Unfortunately the links to all of the pseudo-catalogs were apparently removed sometime in the last few months, so even these are not accessible any longer, except to those of us who were able to capture them beforehand using a web page clipper utility (Print Edit WE, HTtrack, etc.).
