My focus is more on colonial times, but I've read a bit about this especially for the Nahua. Elizabeth Hill Boone has written a lot about this topic, and I especially liked her "Stories in Red and Black: Pictorial Histories of the Aztecs and Mixtecs". It goes into some detail on different genres, and on the role of the writers and/or wise men and how it changed with colonisation.

She also co-edited books on related topics. Two of them take a broader approach, including articles on Mayan, Andean and other writing forms as well. One of them is "Writing Without Words: Alternative Literacies in Mesoamerica and the Andes", co-edited with Walter Mignolo; a more current one is "Their Way of Writing Scripts, Signs, and Pictographies in Pre-Columbian America" (co-ed. Gary Urton). The first one has some articles on social context as well, not sure about the latter - you could have a look which seems more interesting for you.

Mignolo has written quite a bit about pre-Hispanic knowledge production as well, but with a stronger focus on colonial changes (and he tends to have rather strong views) - e.g. in "The Darker Side Of the Renaissance". I could recommend you more on early colonial times, and lists of early codices of colonial Mexico in case that's something you're also interested in. Hope this helps.

Edit: Forgot to mention that at least for the Nahua (but also for other Mesoamerican population groups) we don't have many pre-Hispanic sources left, hence my references to early colonial sources which are often said to follow and carry on traditional conventions.

You can find a lot in our booklist- I'll single out some from there that focus on writing and add some more.

• Breaking the Maya Code by Michael Coe is the example of what popular history can be. It's a thrilling account of the decipherment of Maya writing, which Dr. Coe played a big part in.

• Reading the Maya Glyphs by Coe and Mark VanStone is a sort of workbook companion to Coe's history. It teaches the fundamentals of Maya writing and is handy guide for further studies.

• Chronicle of the Maya Kings and Queens by Simon Martin and Nikolai Grube is less explicitly about the glyphs and more about what we can learn from them. Still, Martin and Grube are skilled epigraphers who reveal the history of several important city states with emphasis on how archaeologists and epigraphers work.

• Maya Decipherment is David Stuart's blog and a great thing to follow. Simon Martin and Stephen Houston frequently contribute, as do a handful of others. Lots of great articles of various topics,

• FAMSI has a great selection of resources on all kinds of Mesoamerican writing. Josserand & Hopkins' Glyph Workbook is generally better than Coe & VanStone's, if less official. The Kerr Vase Database is fun to look through, and the searchable dictionaries are useful.

• Corpus of Maya Heirogylphic Inscriptions from Harvard's Peabody Museum is a handy database that's easy to browse and nice to have on hand when other books/articles reference a monument. Sometimes has translations, almost always has transcriptions.
