Great info! To add on, MangaUpdates has a ton of info about series including which jp publisher and magazine they are from (magazines are helpful to know because they often have a similar art style or tone of story, so knowing you like multiple series from, say, Hana to Yume, is a good clue you may enjoy other series from that magazine).

We have mangaupdates.com to find the mangas of a certain author, but I am trying to find smaller works of authors I enjoy (such as a one-shot on Shounen Jump, for instance) and I find that our western databases are quite lacking. Do you guys know of a more comprehensive source of information (possibly a japanese website)? Source: over 1 year ago

If it's a manga adaptation, you can look it up on mangaupdates.com and look at the Anime Start/End Chapter section. It will tell you the last chapter adapted by the anime (among other things). You can then check to see if that is the last chapter of the manga. Source: over 1 year ago

You can go to mangaupdates.com and there they have a list of names, but more importantly known scanlations. If you click Search for all releases for this series it'll show what the fan name actually being used is. The link to official translations and English, will show you what the official English name is, but they also update the title on the page to show the official English name. Source: over 1 year ago
