>"Plans of all types of small homes"
Ah the home builders catalog, a classic. That one is grouped by style, so if one doesn't appeal to you, just keep scrolling to the next one. You can also click the button on the bottom bar with four little squares to enter thumbnail view, so you can see a bunch more pages at once while scrolling; this works for most books on the site :)

There are many styles that fall under the umbrella of American Victorian, but the one people usually picture is Queen Anne. Some good plans for those, as well as some large manors, are here:

Federal style (listed here as New England colonial) along with many others, as well as in-depth guides on interior decor, here:
