History of swimwear

Step 2

Little wonder that bikinis have fit in almost from the start

Question

Scholars researching the history of swimwear often rely on archived fashion brand websites and defunct retail catalogs preserved in large-scale web archives. Identify the web analytics company that began donating its web crawl data in 1996 to the nonprofit organization that operates the Wayback Machine. Additionally, name the specific 2008 crawl collection contributed by this company and describe its current public accessibility status, including any embargo practices associated with how the data are incorporated into the archive.

Answer length: 200-300 words.

Depth checklist
  • Alexa Internet + Identified as the web analytics company donating crawl data since 1996 to the Internet Archive
  • Alexa Web 2008 Crawl + Identified as the specific 2008 collection donated by Alexa Internet and noted as not publicly accessible
Width checklist
  • States that the company began donating crawl data in 1996
  • Explains that the data are donated to the nonprofit organization that operates the Wayback Machine (Internet Archive)
  • Mentions that crawl data flow in regularly and are added after an embargo period
  • Correctly names the 2008 crawl collection
  • Clearly states that the 2008 crawl collection is not publicly accessible
Examiner rationale

The question anchors itself in the domain of swimwear history by framing the need for archived fashion websites, but the solver must use logical reasoning to identify the web analytics company known for donating crawl data to the Internet Archive (Deep). It then requires aggregating multiple details: the start year of donations, the recipient organization, the embargo process, and the name and access status of a specific 2008 crawl collection (Wide). The entities are not named directly, ensuring the respondent must discover and verify them through external research.

Score 1 - 0

First, Deep Logic: Agent A correctly identifies **Alexa Internet** as the web analytics company donating crawl data since 1996 to the Internet Archive and names the **Alexa 2008 Web Crawl**. Agent B fails to identify any entity and refuses to answer, so it fails DEEP logic entirely. Second, Width/Completeness: Agent A addresses most checklist items (1996 donation, Internet Archive, 2008 crawl name, embargo practices, incorporation into Wayback). However, it incorrectly states that the 2008 collection is publicly accessible, whereas the ground truth specifies it is not publicly accessible. This is a significant factual error on a key sub-point. Agent B provides none of the required details. Finally, User Experience & Presentation: Agent A provides a structured, citation-rich, informative answer with clear formatting and contextual explanation. Agent B offers a minimal refusal with little utility. Because Agent A gets the core entity and most details correct but makes a major factual mistake about accessibility, it cannot receive MUCH_BETTER. However, since Agent B fails the core entity entirely (DEEP failure), Agent A is the flawed but clearly superior response.

The web analytics company that began donating its crawl data to the Internet Archive in 1996 is **Alexa Internet** (later acquired by Amazon in 1999) [1]. The specific 2008 collection contributed by Alexa is known as the "Alexa 2008 Web Crawl" or "alexa2008" within Archive-It partnerships [2]. As of 2024, this collection remains **publicly accessible** through the Wayback Machine, though with significant embargo and access restrictions that affect how scholars can retrieve data [3]. The Internet Archive implements a **6-month embargo period** for Alexa crawl data, meaning the most recent six months of crawls are not immediately available to public users [4]. Additionally, data from the Alexa crawls are incorporated into the Wayback Machine through **selective sampling** rather than complete ingestion; only a fraction of the crawled URLs are made browsable, while the full dataset requires special researcher access agreements and is subject to **robots.txt retroactive removal policies** [5]. These practices reflect the Archive's compromise between preserving corporate-donated data and managing server capacity while respecting publisher rights. ## References 1. Internet Archive.

Perplexity

8.6s
The provided search results do not contain the specific information needed to answer this query about which web analytics company began donating crawl data to the Internet Archive in 1996, the identity of a particular 2008 collection, or its current accessibility status and embargo practices. While the search results reference the Wayback Machine and general web archiving resources[8], they lack details about the Internet Archive's data donation partnerships, specific crawl collection identifiers, or the technical policies governing how contributed datasets are integrated and made publicly available. To accurately answer this question, a search focused on the Internet Archive's organizational history, donor partnerships, and collection documentation would be necessary. This would require access to the Internet Archive's detailed records about corporate data contributions, specific crawl collection metadata from 2008, and current policies regarding embargoed or restricted access to contributed materials. The query asks for highly specific historical and technical information that requires sources directly addressing the Internet Archive's data acquisition timeline and governance practices—information not present in the current search results. ## References [8] Wayback Machine - Internet Archive. http://wayback.archive.org
