Digital preservati<strong>on</strong> is “a process by which digital<br />

data is preserved in digital form in order to<br />

ensure <strong>the</strong> usability, durability <strong>and</strong> intellectual<br />

integrity <strong>of</strong> <strong>the</strong> informati<strong>on</strong> c<strong>on</strong>tained <strong>the</strong>rein” 152 .<br />

8.2.1. TECHNICAL DEVELOPMENTS<br />

Technically, digital preservati<strong>on</strong> implies setting<br />

up strategies, such as migrati<strong>on</strong> <strong>and</strong> emulati<strong>on</strong>.<br />

Thorough research <strong>and</strong> studies that have been<br />

<strong>and</strong> are still being c<strong>on</strong>ducted about digital<br />

preservati<strong>on</strong> emphasize <strong>the</strong> complexity <strong>of</strong> digital<br />

objects <strong>and</strong> <strong>the</strong> many characteristics to be<br />

accounted for in a l<strong>on</strong>g-term preservati<strong>on</strong><br />

scheme. As underlined in <strong>the</strong> EC i2010:Digital<br />

Libraries Communicati<strong>on</strong>, at present <strong>the</strong>re is<br />

little experience with digital preservati<strong>on</strong>.<br />

Questi<strong>on</strong>s are raised that deserve more<br />

research <strong>and</strong> practical implementati<strong>on</strong> regarding:<br />

<strong>the</strong> exact c<strong>on</strong>tents <strong>of</strong> a journal that need to be<br />

preserved (selecti<strong>on</strong> criteria); <strong>the</strong> l<strong>on</strong>g-term<br />

sustainability <strong>of</strong> digital preservati<strong>on</strong> supports;<br />

st<strong>and</strong>ards for preservati<strong>on</strong> processes <strong>and</strong><br />

techniques –<strong>the</strong> XML mark-up language <strong>and</strong><br />

<strong>the</strong> OAIS model (Open Archival Informati<strong>on</strong><br />

System) 153 are promising; metadata about<br />

preservati<strong>on</strong> –such as <strong>the</strong> scheme recently<br />

defined by OCLC <strong>and</strong> RLG 154 ; methods protecting<br />

<strong>the</strong> document au<strong>the</strong>nticity; <strong>technical</strong> strategies<br />

for sustainable archiving systems.<br />

Research should also be supported in closely<br />

related domains that have a direct impact <strong>on</strong><br />

preservati<strong>on</strong>, such as: <strong>the</strong> creati<strong>on</strong> <strong>of</strong> userfriendly<br />

XML editing tools enabling authors to<br />

directly <strong>and</strong> easily create articles in XML format<br />

–avoiding <strong>the</strong> subsequent necessary XML<br />

c<strong>on</strong>versi<strong>on</strong> for optimal document preservati<strong>on</strong>;<br />

<strong>the</strong> automatic generati<strong>on</strong> <strong>of</strong> metadata for large<br />

amounts <strong>of</strong> documents to be preserved; <strong>the</strong><br />

creati<strong>on</strong> <strong>of</strong> interoperable quality archives to<br />

deposit documents in different places <strong>and</strong><br />

improve preservati<strong>on</strong> c<strong>on</strong>diti<strong>on</strong>s.<br />

8.2.2. ROLES AND RESPONSIBILITIES<br />

In <strong>the</strong> print era, <strong>the</strong> l<strong>on</strong>g-term preservati<strong>on</strong> <strong>of</strong><br />

scholarly journals was ensured formally by <strong>the</strong><br />

nati<strong>on</strong>al library through legal deposit, as well<br />

as informally by many o<strong>the</strong>r instituti<strong>on</strong> <strong>and</strong><br />

research libraries that subscribed to <strong>the</strong> journals.<br />

Today, <strong>the</strong> resp<strong>on</strong>sibilities for digital preservati<strong>on</strong><br />

<strong>of</strong> scholarly journals are not yet clearly<br />

established. This is however a crucial issue for<br />

<strong>the</strong> future l<strong>on</strong>g-term availability <strong>of</strong> research<br />

results.<br />

Very few publishers make public <strong>the</strong>ir l<strong>on</strong>g-term<br />

preservati<strong>on</strong> policy. The most recent surveys <strong>of</strong><br />

publishers (dated 2003) 155 show varying<br />

degrees <strong>of</strong> c<strong>on</strong>cern <strong>and</strong> involvement; while an<br />

EC study reports that most publishers deposit<br />

<strong>the</strong>ir digital publicati<strong>on</strong>s <strong>of</strong>fline (Oskamp,<br />

2003), an ALPSP survey indicates that <strong>on</strong>ly 50%<br />

<strong>of</strong> <strong>the</strong> publishers have taken formal provisi<strong>on</strong>s<br />

for <strong>the</strong> l<strong>on</strong>g term preservati<strong>on</strong> <strong>of</strong> <strong>the</strong>ir journals<br />

(Cox <strong>and</strong> Cox, 2003). The current provisi<strong>on</strong>s<br />

involve multiple <strong>and</strong> distributed resp<strong>on</strong>sibilities:<br />

own arrangements, agreement with nati<strong>on</strong>al<br />

library or ano<strong>the</strong>r library, deposit with o<strong>the</strong>r<br />

third parties (JSTOR, NLM-PubMed Central,<br />

LOCKSS, OCLC, INASP, Ingenta…).<br />

Publishers’ own arrangements<br />

Digital preservati<strong>on</strong> is costly <strong>and</strong> publishers<br />

expect return <strong>on</strong> investments. There is a risk<br />

that publishers will stop to ensure digital<br />

preservati<strong>on</strong> when licensing access to digital<br />

archives will no l<strong>on</strong>ger be pr<strong>of</strong>itable.<br />

It appears most likely that publishers will<br />

assure initial archiving <strong>and</strong> provide access to<br />

digital archives as l<strong>on</strong>g as publicati<strong>on</strong>s bear a<br />

commercial value, while making formal<br />

arrangements for l<strong>on</strong>g term preservati<strong>on</strong> with a<br />

third party.<br />

Nati<strong>on</strong>al libraries <strong>and</strong> legal deposit<br />

“Legal deposit is a statutory obligati<strong>on</strong> that<br />

requires any organizati<strong>on</strong>, commercial or<br />

public, <strong>and</strong> any individual producing any type<br />

<strong>of</strong> documentati<strong>on</strong> in multiple copies, to<br />

deposit <strong>on</strong>e or more copies with a recognized<br />

nati<strong>on</strong>al instituti<strong>on</strong>” (CEDARS, 2002). Such<br />

instituti<strong>on</strong>s aim to preserve <strong>the</strong> nati<strong>on</strong>al<br />

cultural <strong>and</strong> intellectual heritage, <strong>and</strong> to<br />

provide access to it, although access is <strong>of</strong>ten<br />

limited from inside <strong>the</strong> premises <strong>of</strong> <strong>the</strong><br />

instituti<strong>on</strong>. Nati<strong>on</strong>al legislati<strong>on</strong>s are progressively<br />

being adapted in different countries to include<br />

deposit <strong>of</strong> digital materials, for instance in<br />

Austria, Germany, Great Britain, Canada,<br />

Norway, Denmark, Italy, France (project) 156 .<br />
