TITLE: Wiki for consequences of axiom of choice?
QUESTION [31 upvotes]: I raised the following question as part of another MO question, but I am following the suggestion of Nate Eldredge to make it a question in its own right.
For many years, there has a been a valuable web resource, hosted by Purdue, on the
Consequences of the Axiom of Choice.  Unfortunately, the page is no longer functioning, as you will quickly discover if you try submitting a form number. The URLs have changed. I suspect that Purdue redesigned its website at some point, changing the URLs, and that since Herman Rubin died a couple of years ago, there is now nobody responsible for maintaining the Axiom of Choice page. I tried emailing a couple of random people in the Purdue mathematics department to find out if something could be done to revive the page, but have received no response.
I am wondering if there is a way to revive this resource, ideally in a way that will prevent it from suffering a similar extinction risk a few years down the line.  Perhaps some people can turn the page into a wiki, much in the way the OEIS evolved from a personal project of Neil Sloane's into a wiki?  Also, maybe someone reading this knows more than I do about the situation at Purdue and can comment on what would be involved in making the data publicly available again.

REPLY [7 votes]: Paul Howard is a colleague of mine here at EMU. Several years ago I asked him if I could try to put his book into an online format (with a database underneath and Ruby on Rails on top).
My progress has stalled on the last 2 years, but you can see what we were able to do at http://104.237.130.142/consequences.

In response to comments below:
The links at the top of the page correspond to different aspects of Paul's book.
In order, the

articles, authors, journals, books, and excerpts links give information about every one of them listed in the book. if you click on the authors link, for example, you'll see every author listed in the book. click on an author, you'll see information about papers by that author that were cited in the book
forms link:  goes to a page that lists every equivalence class of forms of the axiom of choice. if you click on a specific form, you'll see basic information about that equivalence class.
models link: goes to a page that has information about each of the models of set theory; click on one of the models, and you'll see, for example, a list of all the forms of the axiom of choice that are known to be true in that model, (each with its own link), a  list of all the forms of the axiom of choice that are known to be false in that model), along with a lot more information.
notes link: Paul and Jean included a lot of little independent proofs of things that they did not find in the literature. This link lists all of the notes, and clicking on any note takes you to the statement and proof
implications link: Paul and Jean classified the different implications by 6 different types; this page lists all of the implications by type. Each type of implications has its own page; going to that page, and click on an implication, and you'll see information about the forms involved and how that implication was derived
tools: this was something that Paul had on his site that I reproduced here. You can put in versions of the axiom of choice by number and make little implication arrays, etc.

I hope this helps; I apologize for the length.
