As Of is a small historical-news research/hobby project. Its crawler identifies itself as AsOfBot and is used to verify publication metadata and build historical news indexes.
As Of does not intentionally bypass authentication, paywalls, CAPTCHAs, explicit technical blocks, or individualized access revocation. Raw publisher HTML used for experimental sources is processed ephemerally rather than retained as a hidden page mirror.
For indexed articles, As Of primarily keeps publication metadata such as headline, publisher, URL, publication date/time evidence, source classification, and limited search data. Readers are directed to the original publisher for the source article.
Publishers can request that crawling stop or that publisher-derived material be withdrawn. Experimental sources are designed to be disabled and purged independently.
