A simple name search will pull all images where the name shows up. In this example, notice that all types of works are included as well as other artists with the same name or works that reference that artist. In the first column, there are filters available that will allow you to limit to a specific type of work, such as architecture.
A search on a particular building provides fewer results, but still includes works that are related. For example, the photograph included is a close up of a chair in front of a bookshelf within the Laurentian Library. So while it is related to the keywords, it is not necessarily representative of the architecture work. You can use the classification limiter are in the first column to limit to architectural works.
The numbers shown beside the classification limiter indicate the number of images available when that limiter is applied. You can apply multiple limiters as well, if you want, for example, specifically drawings of architectural works.
Once you select an image, you are taken to a page with all of the information ArtStor contains about the image, as well as ArtStor's image viewer which allows you to zoom in to a part of the work. The thumbnail map in the bottom left has a red box to show what part of the image you are magnifying.
Sure, you can do a google search for a building and get an image, but there are better images out there than someone's vacation photo. If you find an image online you will need to carefully evaluate an image and its source to ensure that it is actually an image of what it says it is an image of, is free of distractions from the main focus, taken in a way that is unedited and representative and accurate in color and size. Additionally, getting a high-resolution image can be very difficult, as often images uploaded to the web are limited by in size and pixels. However, if you use ArtStor you gain access to extraordinarily high-quality images that have been contributed by professionals and reviewed to ensure the most representative image in comparison to the original. In this example, ArtStor is on the left, with a "large image" from the web (850x1163 pixels) zoomed-in approximately the same amount.
