Vintage patterns can be a great resource for all sorts of knits and because many are out of copyright they are free to access.
I have two websites I go to for free vintage patterns. They are freevintageknitting.com and freevintagecrochet.com. These are my first stop for newer vintage patterns because it collects old out of print pamphlets and makes them easy to read. The sites also have information on discontinued yarn, hook and needle conversion and more. They are a great start to historical (or vintage) knitting.
For older books you can head to archive.org/details/knittingreferencelibrary. Books in this collection are simply photocopies so you would need to translate the patterns yourself. But it does contain Victorian to WW 2 books.
Blogs and sites like Ravelry are also a good place to start looking for patterns. There are many free versions of vintage patterns and paid for ones can be helpful because the authors will do the work of updating the needles, yarn and pattern wordage.
