EDIT 2: Why are there resources for languages that are not “regional”?
When I first posted this tread I choose to name it regional language …, because I had in mind to find resources for languages like Breton, Catalan and Piemontese. However, as time as gone on I have found resources for languages that are not really regional languages but are not mainstream.
I have decided to add resources for languages like Kazakh, Burmese, etc. languages that are not mainstream but does not fit the regional description (official language of independent country).
Edit 1: I removed the questions of this post in order to put more ephasis on the resources as the questions did not get that much attention. Also in most cases I sort of knew the answers, one of the questions was also heavily linked to resources anyways.
I have a fascination for regional dialects/languages and I have been playing around with the idea of delving into regional languages. I have no solid plans but I am very interested in Piemontese, Alsatian and Breton.
My resources suggestion (and others to that are posted further down)
Verbix
Is a verb conjugation verb site that have conjugations in more obscure languages such as french creole languages, occitan and Welsh among others.
Tintin in regional languages (french regional language)
fnac.com is a french (I assume) website that have some Tintin cartoons in regional languages such as alsacian, arpitan and monégasque. They don’t have an exhorbitant amount of them. They do however seem to have a quite good stock of regional language books on a whole, mostly grammar books.

Le petit prince (Italic languages)
Amazon has a version of The little prince in many different Italic languages/dialects. The first link is to the book in Neapolitean language further down the page at “customers who boguht this book also bought” sections there’s the book in other languages.
Here is a link to a page that shows in which all languages The little prince has been translated into, which might come in handy when looking for it in translation.
Petit Prince Collection - 544 translations
Is a web site (seems) dedicated to the preservation of regional language of the world. They have articles on many lesser known languages of the world. The admins of the website say that they are actively updating the site. However, the coverage of some language is quite sparse.

From Bokus I have found the following book (first link under breton). It’s a Swedish website (however, they do have international shipping) that have books on some more obscure languages.

“Armiarma.eus, seems to have quite a lot of copyright free classics in Basque. I first found this site about a few weeks ago and I remember when I did click on some link, download button, etc. I did get a warning. So, caution is advised. The second link leads to a list of books with options to download as pdf or epub. I tried a few of them and they seem to be fine.”
I found from this website a Basque grammar book it seems quite old but it seems like a fairly standard small grammar guide which could be useful.
