Very true! I've spent much of my working life helping those with knowledge make it accessible to those who need it. Though not a great expert on anything else, I do know how to do that. Mary Sue Ittner and the other PBS members who work on the wiki do a great deal toward this end. And yes, I know I should contribute more, but I'm slow about editing my photos down to wiki size. Like the cleaner who doesn't do windows, I'm the editor who doesn't do graphics (though I know how to direct someone who does). I'm not a web designer, but I work as a copy editor for Oxford University Press, which is moving a lot of its famed reference works into online sites available by subscription. This has made me aware of the many devices that help readers navigate clearly and quickly through a reference site. My current work is on annotated bibliographies of a vast number of fields of study. I'd like to develop a similar bibliography for the PBS wiki sometime -- one that wouldn't cost users $200 a year to access! If I have some free time this winter, perhaps I can collaborate with someone to develop it. The PBS could even make a little money from it if there are links to vendors who sell the books ("affiliation"). The Oxford bibliographies also include web resources with links the user can click, and I think this is not hard to set up? Jane McGary Portland, Oregon, USA
