The Victorian section of Jack Lynch's helpful Literary Research Tools offers one list of useful links, as does Alan Liu's meta-page, Voice of the Shuttle. This introductory essay published in 1995 may now be of some historical interest!
Information about upcoming conferences and other events can frequently be found on the Victorian section of Penn's useful Call for Papers site, as well as NAVSA's blog, "Of Victorian Interest".
For a more comprehensive listing of Victorian websites, see one of the general guides noted at the top of this page; resources for various kinds of 19th-century research can of course be found throughout the VRW, while links to museums and other places of Victorian interest can be found on the research trip page. What follows here is a modest selection of useful, entertaining, and unusual webpages, including some smaller sites that tend to get lost in the shuffle of the big meta-page listings.
