Universal Century Gundam
I'm a big fan of the Universal Century timeliness in Gundam, and this is all the English licensed manga I'm aware of for it besides The Origin.
Picture 2: Thunderbolt. Hands down the best Gundam manga on the English market.
Picture 3: Ecole Du Ciel. Really good, but unfortunately dropped in English and also incomplete in Japan, to my knowledge.
Picture 4: 0079, my favorite adaptation of the original series. Also Incomplete in English, missing 3 volumes. Volumes 1 and 2 have comic book and large print variants. The small print paperbacks of 1 and 2 are shown in photo 1, but not 3.
Picture 5: 0083. This is an "animanga", that is to say a manga made up of stills from the anime. It's a pretty poor adaptation that doesn't read particularly well, but it's the complete series.
Picture 6: Lost War Chronicles. A short One Year War side stories. Good, not great.
Picture 7: Blue Destiny. Not good.
Picture 8: Char's Counter Attack and Cucuruz Doan's Island. The two currently ongoing UC series, I've consumed them through other forms of media but I haven't read these yet.
Picture 9: Technical Manuals. I included the whole set in the first picture, but only the ones that deal with UC for this photo. These have a ton of cool technical information on the robots, timelines and character information, and color art. They frustratingly include almost nothing about Zeta, my favorite series.
Picture 10: A sample page of UC art from the Haruhiko Mikimoto artbook.
Picture 11: My current Gunpla collection.
