no. the majority of pdf files are inaccessible to screen-readers unless its a structured and unlocked pdf (for example copy-paste should be unlocked) Eirini ________________________________ Απο: Leslie Carr <[log in to unmask]> Προς: [log in to unmask] Στάλθηκε: 4:09 μ.μ.

Word and Epub on the other hand are compatible with screen-readers. If you could go with a multi-modal way then you could serve the needs of all potential users in an inclusive education environment and enhance preservation. BTW, has anyone used METS for preservation?

If anyone is interested in doing more, I've recently written up a summary of a number of new community driven or crowd sourced approaches to digital preservation: http://wiki.opf-labs.org/display/SPR/Support+your+digital+preservation+community Cheers Paul -----Original Message----- From: Repositories discussion list [mailto:[log in to unmask]<mailto:[log in to unmask]>] On Behalf Of Jenny Mitcham Sent: 01 August 2012 09:44 To: [log in to unmask]<mailto:[log in to unmask]> Subject: Re: Policies on depositing MS Word files Hello, I too have been watching this discussion with interest. It is really good to listen to other people's experiences. I would agree with the general consensus on this list of the benefits of keeping a copy in it's original format (whatever that may be). PDF is fine for dissemination but should be used with caution. PDF/a is a far more attractive option and the hope is it will have a bit more longevity. In my previous job at the Archaeology Data Service one of my jobs was to go back to some old pdf files that had been deposited (for dissemination only - we did have a separate preservation version) over 10 years ago. These files were in pdf version 1.2 and over the course of time, our users were beginning to have problems accessing them. Various error messages were popping up on opening the files, most of which were to do with missing fonts. These errors were rendering the files unreadable. I had to go back to the original preservation versions and create PDF/a files happy in the knowledge that all fonts would be embedded and that the data within the reports would be readable for a much longer period of time. :-) On the subject of Word docx files. I would argue that these are fine as a preservation format, so long as there is a process of continuous active management within the digital archive and the opportunity to convert to another suitable format as time passes (with appropriate checks to ensure the significant properties of the document are maintained through subsequent migrations ...that is perhaps the tricky bit!).
