:To clarify: .PDF files are *frequently* created with content such as fonts (or really anything other than the actual text) referenced within the document but not *embedded* within the document. This is usually done to reduce file size, but it's usually not advisable. Whether it's a .pdf or a .ppt or a .exe it is best to keep your dependencies embedded whenever possible! | :To clarify: .PDF files are *frequently* created with content such as fonts (or really anything other than the actual text) referenced within the document but not *embedded* within the document.

::Pressed commercial CD-ROMs carry their information between two 0.6 mm thick plastic discs which are glued together, which makes them pretty resilient against scratches on either side – just remove some material with abrasive methods like toothpaste. Often the glue is the bigger issue with low-quality pressings in the long run. This is in contrast to recordable CDs, which are coated with the reflective layer on top of a single disc. –[[User:TisTheAlmondTavern|TisTheAlmondTavern]] ([[User talk:TisTheAlmondTavern|talk]]) 12:24, 31 October 2017 (UTC) | ::Pressed commercial CD-ROMs carry their information between two 0.6 mm thick plastic discs which are glued together, which makes them pretty resilient against scratches on either side – just remove some material with abrasive methods like toothpaste.

: Yet something affected by that would just as likely be affected by "Broken on new OS, not updated". For example, I've got a multimedia encyclopedia which runs on Win 3.11, and thus can't run on 64-bit windows. | : Yet something affected by that would just as likely be affected by "Broken on new OS, not updated".

:: Ehrm... You do realise the limitation is the other way around right? You can't run 64-bit application on 32-bit Windows, but 64-bit windows can perfectly well run 32-bit apps. Though Win 3.11 is far enough back it might actually be a fun challenge to see if it runs :D [[Special:Contributions/162.158.202.202|162.158.202.202]] 10:57, 31 October 2017 (UTC) | :: Ehrm...

Interestingly, static .PDF files are intended to be electronic equivalents of printed books - an electronic microfiche if you will [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 18:57, 30 October 2017 (UTC) | Interestingly, static .PDF files are intended to be electronic equivalents of printed books - an electronic microfiche if you will [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 18:57, 30 October 2017 (UTC) | ||
I'm wondering if data on an older, static, website would still be readable. Would likely still be there (or on archive.org), but might be suffering progressive link rot. Also a little surprised that the start of microfilm is so recent; I remember the library having microfilm readers (that nobody ever used) when I was young enough to spend ages staring at a machine, trying to determine its purpose. Guess it depends on the subject, when it was put into that format. --[[User:Angel|Angel]] ([[User talk:Angel|talk]]) 18:39, 30 October 2017 (UTC) | I'm wondering if data on an older, static, website would still be readable.

Angel, note both the My in the title and the left arrow implying that the resource (like books) were about before Randal had access.

The software not running after OS update is such a Mac problem. Linux updates would break if closed software was commonly available, but open source can be recompiled, and Windows maintain a scarry amount of backwards compatibility, and only system-admin or DRM-crippled software ever stops working.[[Special:Contributions/162.158.202.202|162.158.202.202]] 10:54, 31 October 2017 (UTC) | The software not running after OS update is such a Mac problem.

I wonder if Randall is aware of digital archiving solutions such as those provided by Preservica (https://preservica.com/), formerly part of Tessella plc. Their solutions are aimed at precisely this problem. Their library/museum clients include "the MoMA, the Frick Collection, the Museum of Fine Arts Houston, Yale Library, The National Library of Australia, The Royal Danish Library, The Philadelphia Museum of Art, McNay Art Museum, DC Public Library and the University of Manchester" and their archive clients include "15 leading pan-national and national archives, 18 US state archives, major corporate archives at BT, HSBC, Unilever and the Associated Press".
