When I worked on Main Street USA, sometimes I would get a shift to work the Disneyana shop. In the 1990s, Disneyana was located where the Starbucks seating area is now. Anyways, I remember that the store used to carry an unofficial Disney publication called The "E" Ticket (1986-2009).
The magazine is loaded with first-hand stories, interviews and photos of all things Disneyland. It's a great resource for any Disneyland aficionado.
If you want to read all about who was behind The "E" Ticket and what happened to it, go to this post and it will give you lots of answers. Luckily, some issues are available through The Walt Disney Family Museum. You can even purchase a several CDs if you want the first 24 issues from this fabulous treasure trove of stories and people behind the Disneyland magic.
There are also issues available on eBay from a variety of sellers. If you are ever at a Disneyana Fan Club Event, you can also find some copies at many of the merchant booths.
