I forgot the name of this DIY Book Catalog?

I'm looking for a catalog my Mom used to get of DIY books. It was a small publishing house, a black and white catalog, and they would re-publish a lot of cool out of print things. I think they got their start with radio hobbyists? They had a really impressive list of pretty much everything-- radios, construction, farming, math, hydrogen engines, compost, crafts.... I think the family/company name started with an L and was in the southern half of the US?
