Danas je Nacionalni ISSN centar Srbije poslao obaveštenje da je stručni bibliotečki časopis "Glas biblioteke" dobio ISSN broj (koji ga identifikuje kao jedinstven bibliografski izvor) za elektronsko, tačnije online izdanje. Taj broj se označava kao ISSN (Online) i on je za "Glas biblioteke" 2217-9747. Inače štampano izdanje časopisa (prvi broj objavljen je 1988. godine) ima ISSN 0353-7595.
Ovim je naš časopis postao vidljiviji za istraživače, baze podataka i Internet u celini, čime se i dostupnost objavljenih članaka povećava srazmerno. Iako se novija serija brojeva (od broja 10) nalazi online još od 2006. godine, tek smo 2012. pribavili ISSN za to izdanje, mada smo bili svesni da štampano i elektronsko izdanje predstavljaju dva zasebna entiteta, iako sadržinski istovetna. Moram napomenuti da je do dobijanja broja došlo zahvaljujući razgovoru sa koleginicom Slobodankom Komnenić iz NBS, koja je nakon diskusije o potpuno drugom pitanju pokrenula i temu elektronskog izdanja časopisa. Znači potpuno slučajno, ali smo ispred redakcije zahvalni koleginici Komnenić na toj slučajnosti.
Trenutno je u procesu štampe 18. broj časopisa, čiju redakciju čine dr Dejan Vukićević, mr Marijana Matović, Gordana Đilas, Olivera Nedeljković, Bogdan Trifunović, Nataša Popović, Danica Otašević, dok je urednik Danica Otašević. Web stranica časopisa, kao i online izdanja poslednjih osam brojeva dostupni su na adresi http://www.cacak-dis.rs/izdanja/casopisi/glas-biblioteke/. Na istoj adresi nalazi se poziv za radove i Uputstvo za autore.

This is the continuation of discussion on the Digital Preservation mailing list of the American Library Association, but this time with the changed title "Cloud concerns". I believe these lines stress important issues when omnipresence cloud services are taken into consideration for digital preservation. As previously said, the names of posters of original emails are omitted. Full credit goes to ALA and respective authors.
Bruce raises an issue regarding cloud storage that has nagged at me – we seem to have some ambient mistrust of the cloud in the digital pres community, yet wide acceptance that “an array of some kind that constitutes a logical volume” will be the standard means of storage. Those things seem at odds to me. A cloud system is an array that constitutes a logical volume, is it not? What’s not to like?
Optical media are not recommended for preservation purposes. Beyond the short lifespan (which may have been lengthened with recent developments) is the limited storage space and constant monitoring to ensure there are no errors. By the time you are setup to do a proper job with optical media it is more expensive and cumbersome than it is to use multiple copies on hard disk and tape, or even in the cloud if you are a trusting soul. Optical media shine when you need a portable copy for presentation and when there is also no streaming version available. Media is not the key to preservation. A comprehensive system that protects your assets and a plan that includes monitoring technological trends for eventual migration of the essence from one file format to another when obsolescence threatens is the key. Please see IASA-TC 04 section 8.1.1 regarding optical media. IASA-TC 04 is available in a web version for free.
You may have noticed that file sizes are not decreasing. This means that increasingly your files will not necessarily be on a single, particular piece of media but will most likely be spread across an array of some kind that constitutes a logical volume.
I can distill my mistrust of the cloud, although it is context-specific and I would agree that cloud storage might make sense for many situations. (Hmm, I feel a flowchart/decision tree coming on, but that will have to wait.)
My story goes back to a not-too-distant audit that our IT shop endured, and I was able to observe parts of the process. Since Social Security numbers are among the most sensitive type of data that libraries have had over the years, and since our hosted ILS system did contain some SSNs in old layers of patron data, to satisfy the auditor, we had to go to the vendor to get a statement that there had been no unauthorized access to that info. I think the auditor even wanted logs (!), which seemed silly to me, since it was really like proving a negative and could easily have been doctored anyway. So, I see the vendor in this situation as a type of cloud, if you will, with third-party service level agreement terms standing in control of our crown jewels. Replace SSNs in this scenario with restricted data from our archives, and I think the problem begins to reveal itself. If libraries and archives are to retain their trusted status as knowledge repositories in society’s eyes, then as institutions, we need to be as sure as we can that what we preserve is protected inside and out from neglect, malicious behavior, entropy, etc. Handing off core mission functionality to the custody of contractual service terms involves a level of risk I would prefer to avoid. Years ago in Margaret Hedstrom’s DP class in grad school, we had a lot of David Bearman on our reading list, and he emphasizes the need for archival material to “hold up in court,” which is why provenance matters so much. Chain of custody, like any other chain, is only as strong as its weakest link, so avoiding third parties as much as possible seems most prudent to me in the context of control over digital data in libraries and archives. I admit this is not always possible, but risks are things we balance and manage.
To the original question for this thread, I wanted to say that, as an NPR listener and fan for almost all of my adult life, I would consider the cultural significance of this material to be worthy of the security of a trusted digital repository, perhaps with a LOCKSS- or Fedora-based infrastructure, secured (“dark” or “offline”) where needed, and openly accessible and linkable where possible. Services like Chronopolis are becoming a viable way to pair the accessibility of cloud services with the trustworthiness of the cultural institutions that have built these collaborations.
For me, any mistrust I have is over who is controlling it, and how much say we have over their procedures. My hesitancies over cloud storage offered by an external service are roughly equivalent to my hesitancies over any non-cloud service--do I trust that procedures will be followed around security and privacy, authenticity, replication, disaster recovery, etc.? And do I trust what will happen if the service goes out of business.
Hi - I was about to respond to this thread and then noticed Chronopolis mentioned at the end of the previous message. So … please take what I say with a grain of salt… I promise I was going to say this anyway. ;-)
I think there's a less of a difference in the current day than in previous times between "cloud" services and local storage. In many organizations, storage services, both basic and advanced, have moved to a more collaborative environment. As data size and complexity have grown, larger and more sophisticated data centers are needed. Often these centers are outside the scope of the traditional library computer room, if such even exists. This environment usually means the library working with either central campus computing or large local data centers, etc.
There is then the next level up from this, where organizations are working together to provide storage and storage-based services beyond what can be offered locally. Think here of HathiTrust or the California Digital Library. Similarly, as David Lowe mentions, things like LOCKSS or Chronopolis are also becoming quite prevalent.
In all of these cases, the *same* questions must be asked of the storage environment: is the data safe? Is at accessible? Who's driving "driving the bus" and making sure that everything is OK? And in point of fact, the technology is the *least* important question here. Bruce Gordon is spot-on when he says, "Media is not the key to preservation." A well-formed plan with an explicit set of demands and rigorous monitoring of the systems are the key. This is the case whether the data is stored in the library, across campus or across the country.
The problem with many cloud systems is that they fall down in their transparency. I'll be frank here: I trust Amazon's ability to store bits more than I trust many local storage instances. They have iron and expertise that far outstrips many of us. I don't trust them to give me the kind of audits and logging functions I want though. Nor do I trust that they have my best interests at heart. And that's where the preservation step comes in: I don't doubt they *can* do it, but I'm not sure they *will.* And again, being perfectly frank, those are the same questions I often ask of my local, but external-to-me, storage.
The Justice Department recently seized the servers of a cloud storage service called Megaupload for alleged copyright infringement. Granted this is an extreme situation with a lesser known company, but perhaps still a cautionary tale: http://www.npr.org/blogs/therecord/2012/04/13/150535995/hearing-in-megaupload-case-to-determine-fate-of-users-data
Excerpt: "...But the digital world is different, says copyright attorney Jim Burger. He says in the Megaupload case the court would probably have to appoint someone to sort through the huge amount of material involved.
He says that person would have to say, "'Oh yes, this 100 megabytes is Mr. Smith's and it's legal, it's his personal stuff. But this 50 megabytes is clear infringing.'""
Be careful! Megaupload might, in some ways, be comparable to Dropbox or similar services, but otherwise is an entirely diferent category of cloud-based services. Its sort of like comparing X-Box issues to those around desktop computers because both are boxes with operating systems.
There are vast differences in types of cloud storage services, and some are sufficiently tuned specifically to security issues that it really isn't clear at this point that being hosted in the cloud is necessarily still germane to whether or not an appropriate security plan (anything from dr to provenance) is adequate.
How long it will take us to have the experience to get beyond our emotional reactions to the idea is another matter. Technology is only part of the problem ;-)
