Since my big Languages and Linguistics MEGA folder post is approaching 200k notes (wow) I am celebrating with some highlights from my collection:
Africa: over 90 languages so far. The Swahili and Amharic resources are pretty decent so far and I'm constantly on the lookout for more languages and more resources.
The Americas: over 100 languages of North America and over 80 languages of Central and South America and the Caribbean. Check out the different varieties for Quechua and my Navajo followers are invited to check out the selection of Navajo books, some of which are apparently rare to come by in print.
Ancient and Medieval Languages: "only" 18 languages so far but I'm pretty pleased with the selection of Latin and Old/Middle English books.
Asia: over 130 languages and I want to highlight the diversity of 16 Arabic dialects covered.
Australia: over 40 languages so far.
Constructed Languages: over a dozen languages, including Hamlet in the original Klingon.
Creoles: two dozen languages and some materials on creole linguistics.
Europe: over 60 languages. I want to highlight the generous donations I have received, including but not limited to Aragonese, Catalan, Occitan and 6 Sámi languages. I also want to highlight the Spanish literature section and a growing collection of World Englishes.
Eurasia: over 25 languages that were classified as Eurasian to avoid discussions whether they belong in Europe or Asia. If you can't find a language in either folder it might be there.
History, Culture, Science etc: Everything not language related but interesting, including a collection of "very short introductions", a growing collection of queer and gender studies books, a lot on horror and monsters, a varied history section (with a hidden compartment of the Aubreyad books ssshhhh), and small collections from everything like ethnobotany to travel guides.
Jewish Languages: 8 languages, a pretty extensive selection of Yiddish textbooks, grammars, dictionaries and literature, as well as several books on Jewish religion, culture and history.
Linguistics: 15 folders and a little bit of everything, including pop linguistics for people who want to get started. You can also find a lot of the books I used during my linguistics degree in several folders, especially the sociolinguistics one.
Literature: I have a collection of classic and modern classic literature, poetry and short stories, with a focus on the over 140 poetry collections from around the world so far.
Polynesia, Micronesia, Melanesia: over 40 languages and I want to highlight the collection for Māori, Cook Islands Māori and Moriori.
Programming Languages: Not often included in these lists but I got some for you (roughly 5)
Sign Languages: over 30 languages and books on sign language histories and Deaf cultures. I want to highlight especially the book on Martha's Vineyard Sign Language and the biography of Laura Redden Searing.
Translation Studies: Everything a translation student needs with a growing audiovisual translation collection
And the best news: the folders are still being updated regularly!
