Hello!
These days I decided I am going to read some of the oldest BL and GL manga out there. While I can easily get to the oldest shounen-ai (by ordering by year and going back enough pages), there are too many manga tagged "yaoi"! The website unfortunately seems to go back only 100 pages, which leads me to yaoi published in the 2010s.
Is there a way to see old manga tagged as yaoi?

Alternatively, do you know any major titles from 70s, 80s and beginning on 90s?
The classic ones I know are: Bronze (and prequel), Fake. Plus all the ones tagged shounen ai so the Hagio, Takemiya and Ikeda's ones.

Camelot is a silly place

Yeah I do wish there wasn't a page limit on how far you can go back ;;

I don't think there is a way around it, but my advice would be to do any of the following:

1- Exclude the Hentai genre (If you aren't into those) as you most likely won't find any stories wroth reading with that tagged on. This would lower the number of Yaoi manga showing up if you search the website.

2- Go to 'Type' in advanced search and select 'Only show results for "Manga"', this will remove other results such as manhwa, manhua, and light novels Yaoi stories which will also show up in the search.

3- On 'Extended Options' in advanced search, you can select 'Show only licensed manga', that would lower the number of Yaoi stories which will show up much much more, and I'm almost sure it'll let you scroll all the way back to see ones from 80s

4- Another option, though I don't recommend doing this and option 3 together, is going to 'Extended Options' and selecting either 'Only show completely scanlated manga' or 'Only show manga with at least one release'. This will also lower the number of results much more, and it'll actually show you the translated Yaoi stories so you won't need to waste time looking through ones which aren't translated.
