The collection of Working Notes is the purpose of the mailing list; it is a series of references, notes and brief articles on various dead media, compiled by list members. You can peruse the collection of Notes via the categorical listings, the numerical index, or the new, as-yet-uncategorized notes. (Notes are assigned a number in the order received.)
You can also do keyword searches using the search engine (see Fig. 23; r.); however you will be assaulted with a banner ad, the price we pay for the 'free' search engine (which is otherwise quite admirable).
