As you might expect, the web is full of architectural sites, some dedicated to a specific city, architect, style or individual building and others of a more general or theoretical nature. I have no intention of trying to be comprehensive but just to point to a few of my favourites along with links to the major listing sites. I promise there will be some more here soon!

• Architext Links, recommended by Architectural Review magazine as "one of the most comprehensive and useful architectural sites of the moment" (September 1999) with vast numbers of links including a large alphabetical list of sites relating to individual architects

• Architronic, an on-line academic architectural journal

• The World Wide Web Virtual Library on Architecture

• Yahoo's architecture listings

• The Links Library's architectural listing with more links than any sane human can handle.

Other sites covering architectural construction toys

• For Richter Anchor Blocks, George Hardy's site is a must.

• For architectural construction toys more generally, but with a special emphasis on Bayko, visit Geoff Lilleker's site. Geoff includes a good definition of what we mean by architectural construction toy.

• Sadly, the american collector Arlan Coffman died in April 1998. Geoff Lilleker has however incorporated Arlan's unfinished site on the joy and history of building toys into his own.

• For all things Bayko, visit Pete Bradley's Baykoman site. Full of information and photographs it also includes information on the Bayko Club, which despite the name is a broad church welcoming collectors of architectural construction sets more generally.

• Joe Lauher has a page primarily devoted to modern Lego, but including pictures a number of old architectural kits too.

• Photographs of some of George Wetzel's vast collection of construction toys show illustrations from the box lids of building toys as well as Meccano and its imitators.

• The american Girder and Panel Collectors Club page has useful information about the various sets and some rather nice pictures.

• Visit Girder & Panel and Bridge & Turnpike Heaven for a huge gallery of photographs of sets through the years and lots of information.

• Joachim Kleindienst's site Baukasten Sammler is a wonderful site that has a great deal of information (in German) and lots of photographs.

• Jim Hughes' Brick Fetish site has a timeline history of Lego with lots of illustrative pictures.

• To play with virtual blocks on screen visit Maurici Carbó Jordi's Geocities site, which forms part of a larger and very interesting site which uses graphical means to show mathematical and logical ideas.
