Of course, the issue of persistent identification predates the Internet. Over centuries, writers and scholars developed standards for [[citation]] of paper-based documents so that readers could reliably and efficiently find a source that a writer mentioned in a footnote or bibliography. After the Internet started to become an important source of information in the 1990s, the issue of citation standards became important in the online world as well. Studies have shown that within a few years of being cited, a significant percentage of web addresses go "dead",<ref>{{Cite arXiv | eprint=1105.3459| last1=Sanderson| first1=Robert| last2=Phillips| first2=Mark| author3=Herbert Van de Sompel| title=Analyzing the Persistence of Referenced Web Resources with Memento| year=2011| class=cs.DL}}</ref><ref>{{Cite book|title=Vanishing Act: The Erosion of Online Footnotes and Implications for Scholarship in the Digital Age|last=Bugeja|first=Michael|year=2010|isbn=978-1936117147}}</ref> a process often called [[link rot]]. Using a persistent identifier can slow or stop this process.

An important aspect of persistent identifiers is that "persistence is purely a matter of service".<ref>{{cite web|last1=Kunze|first1=J.|title=The ARK Identifier Scheme|url=https://tools.ietf.org/html/draft-kunze-ark-18}}</ref> That means that persistent identifiers are only persistent to the degree that someone commits to resolving them for users. No identifier can be inherently persistent, however many persistent identifiers are created within institutionally administered systems with the aim to maximise longevity.

However, some regular [[Uniform Resource Locator|URLs]] (i.e. web addresses), maintained by the website owner, are intended to be long-lasting; these are often called [[permalink]]s.

Web archiving services such as [[perma.cc]], [[archive.is|archive.today]], and [[WebCite]] offer anyone the ability to archive a web page and create their own persistent identifier for it.
