Simplifies production of catalogues, making every advanced catalogue craftable from previous one. Everything is configurable even number of catalogues per tier, default is 10, meaning extended catalogues cost 1k of basic catalogues. All 5 kinds of catalogs available. Research cost of each one is 50 and tier of corresponding science is connected to tier of catalogue (in the screenshot i am using another mod called Space Exploration - Simplified "https://mods.factorio.com/mod/se-simplified" from which i got the idea, thats why research cost is 200 but tier 1 science and i recommend downloading it as it expands capabilities of this mod)
