There was no web page with swedish Lego catalogs, and I thought I should try to fix that.
You can find catalogs from 1966 onwards here. However the catalogs after 1998 are very large and it
will take a lot of time to scan everything (I often try to add the front picture as a placeholder).
From 2020 onwards I try to collect Legos own PDFs to save time. This page also has a lot of catalogs for themes like Legoland, Fabuland and Trains.
