Hello, everyone. I'm Hamideh Mimari, senior assistant of Iran ISSN National Center, member of ISSN International Center Governing Board, and I'm working in National Library and Archives of Iran, Tehran. My presentation title is The Endless Life of O.H.O.N.O.S. From Meets to Reality,

the survey on present the statue of vanished O.H.O.N.O.S. in Iran and future prospects. What is open access? Open access is publishing model for scholarly communication that makes research information available to readers at no cost,

as opposed to traditional subscription model in which readers have access to scholarly information by paying a subscription. What is management access? The preservation of the scholarly course has been a point of concern since the beginning of knowledge production. With print publication, the responsibility rested primarily with the librarians.

But the shift towards digital publishing, and in particular the introduction of open access, have caused ambiguity and complexity.

Consequently, the long term accessibility of journals is not always guaranteed, and they can even disappear from the web completely. In the year 2012, the ISSN International Center, under the guidance of its Governing Board, play a useful part in the promotion of open access to scholarly resources.

The ISSN International Center, with backing from UNESCO's communications and the support of 89 national centers, in the year 2013 opened a web services called the Directory of Open Access Scullery, which is fed by national ISSN centers.

A unique feature of ROAD lies in the provision of global statistics, thus allowing users to monitor the development of OA resources across the globe.

Journals in Iran. Along with the emergence of electronic journals in the world, Iranian e-journals also grow day by day. The statistics show that the number of e-journals increases every year compared to French journals.

Open access journals in Iran. Since 2013, Iran ISSN National Center, along with the establishment of ROAD, like other ISSN network centers, started cooperating with ROAD. According to ROAD Activity Report for the year 2018, Iran is one of the top 10 contributing countries in OA publications.

A statue of open access journals in ROAD shows that 2,162 journals are published as open access, 84 journals are archived in Keepers Registry, and 66 titles have been seized.

Objectives. To the fact lack of available data resources that follow and tracking the vanished OA's consistently and comprehensively. And since there is no workers in Iran, so we do not know how many OA's have been vanished over time.

The aim of present study be conducted to determine the number of Iranian vanished OA in the rogue methodology. At the birth, we define vanished OA journals as journals that publish at least one volume

as immediate OA, after which production ceased, and the journal completely disappeared from the web and vanished. And then we cannot find it in a wayback machine or other indexing databases.

The research publication population includes all Iranian open access journals in various fields in the role between the years 2010 and 2020. We choose journals in all subject areas such as social science, applied science, medicine, and etc.

We sorted journals by year, and in each year we divided them into three categories, academic journals, non-academic publishers, and self-publishers. We started to examine both URLs, and if the address is not active, we search both title and URL of the journals in search engine and beback machine.

Through various searches, we found that in some cases only the URL of the journals has changed and the journals is still active and current.

So we recorded the number of these records by category as the journals with changed URL and also listed journals that were completely vanished by category. We should notice that we focus on journals instead of article. After months, we reject URL

of vanished OA journals in the first review to make sure that they were really vanished. Findings Analysis of open access journals by publishers category shows that 10% of publishers belong to

self-publishers, 32% belongs to non-academic publishers, and 58% belongs to academic publishers. In this chart, you can see the percentage of academic, non-academic, and self-publishers by year.

This shows that the highest percentage of vanished journals belongs to category of self -publishers and non-academic publishers, respectively, and academic journals have the lowest percentage of vanished.

This survey shows that 110 open access journals were vanished during these years, including 38 self-publishers, 25 academic publishers, and 47 non-academic publishers.

We can see the number of vanished OA by publishers category and the year. In this chart, you can see the self-publishers statue. In the year 2015, we had the highest percentage of vanished.

The non-academic publishers statue shows that in the year 2014, we had the highest percentage of vanished OA.

If you look at the non-academic publishers statue, you can see the highest level of vanished OA in the year 2017. Look at this chart. This chart shows URL change by publishing category.

Conclusion. Since preserving OA journals is a big financial challenge for publishers, so it seems the highest percentage of vanished OA journals belong to the category of self-publisher.

It may be concluded that academic journals not only have less financial challenges, but also have a more consistent policy. The criteria for assigning OA journals are updated annually and announced by the ISSM International Center to the ISSM network.

The Iran ISSM Center also follows these criteria. It seems that use of this criteria has helped to reduce the number of vanished OA in recent years.

None of vanished OA novels were listed in any of international or local indexing databases. The vanished OA novels were completely removed from the field and it was not possible to contact them to find out how many issues had been published. Keepers registry can protect digital novels which are at risk of loss and need to be archived.

At the end, implementing of national web archives in Iran is essential. Thanks for your attention.
