2. Assess capture completeness and render quality through web browsing
Follow the directions below to evaluate the extent to which any crawl has captured significantly valuable web content, to measure the accuracy of its behavior and appearance in an archival environment, and to recommend the necessary improvements to either/both:
Access web instance in both Wayback and Live Version
To access the live version of the instance under review, simply copy and paste the string (beginning: https://) that follows the identifying information in your starting URL:
Navigate and inventory issues of quality
Enable Wayback QA
Begin by clicking on the Enable QA link within the Archive-It banner that appears at the top of the current archived web view:
Clicking on this link adds a View Missing URLs link to the same header, through which you may view the specific URLs in each page’s archived form that must ultimately be patch crawled in order to complete the instance’s capture:
You may observe the number of links automatically summarized within this link text for each page, but refrain from initiating any actual patch crawls of the missing content until you have completed a more systematic review of the entire archived instance through the Wayback interface. (Each missing URL is progressively added to a summary list of missing URLs from your collection that will be patch crawled later).
Activate Missing URLs
Compare live instance to Wayback rendition
Once you have reviewed the above pages, you may move on to those thematically significant pages that lead to further and/or content-rich “child” pages, such as Catalogs, Collections, Exhibitions, Publications, etc. Again compare each archived view to its live analog, keeping track of any differences in content, functionality, and/or style rendered between them. You may observe the missing URLs summarized in the View Missing URLs header link as you go, but make certain to follow all links in view in order to ensure that all are in fact active and may therefore be detected by the Wayback interface as either archived or missing. This process is essential to ensuring that missing URLs are queued for later patch crawling.
This comparison of live and archived views of the Mitchell-Innes & Nash Gallery website suggests that scope adjustments or patch crawls would enhance the current capture with missing content.
