Sadly, so true! B/c libraries are rare  special snowflakes that don't operate 
by the rules of the rest of the web universe ;)

Speaking of library community web standards re: libguides, can anyone share 
what their library uses as metrics for success / key performance indicators in 
LibGuides (or non-libguides-based digital research guides)?

I appreciate it. Thank you,

 Bohyun,
 
 That sounds like it could be a great fit.
 
 There would be two final products for what I have in mind:
 
 1. A wiki site (ideally attached to an ALA-affiliated domain name) where we
 can collaborate and break all this down at the topic level. This is the source
 that would be used by the boots-on-the-ground librarians who are actually
 doing UX work and need practical information. It would be continually
 updated. The content would be curated, and there would be a very basic
 approval process for creating new editor accounts.
 
 2. An annually-revised document (again, attached to an ALA-affiliated
 domain
 name) that compiles everything from the wiki together in a format that can
 easily be presented to other librarians and administrators. In my experience,
 a bureaucratically approved document carries a lot more weight in libraries
 than a website, at least in academic libraries.
 
 Topics that would be addressed:
 
 1. Accessibility
 2. Layout patterns
 3. Typography and readability
 4. Best practices for specific library web platforms 5. Recommendations for
 how libraries should implement the guidelines at a management level
 (non-technical)

You will also have support from the LITA Board on this. The document/wiki
can be published/publicised far and wide.  The UX IG can bring the document
to the board and ask for endorsement, which will also help with its
authority.  The IG could also take responsibility for the yearly updating,
and it could turn into scholarly work from there--in the C4L journal, ITAL,
ACRL publications, etc, which would also boost its authority among folks
off-list.

Exciting!

 The point that Sean and Shaun made is a good one. The content being housed

 But you are right that ALA will have a much wider reach to those who will
 benefit from this. (Some ALA divisions like ACRL actually publishes

 impossible to do so.) Whichever route you go, you are welcome to leverage
 LITA UX as your discussion forum and use other tools there as well. IMHO,
 as long as the final content is cross-linked, we will all benefit.

One approach you might take, is to do what the federal government and local 
governments are increasingly doing: selectively adopt industry standards.  So 
like for building code. Most municipalities adopt the generic one and then list 
exceptions.

So the effort is spent reviewing and selecting the best standards (best 
practices, guidelines), and preparing a document, not re-inventing the wheel.

One approach you might take, is to do what the federal government and local 
governments are increasingly doing: selectively adopt industry standards.  So 
like for building code. Most municipalities adopt the generic one and then list 
exceptions.

So the effort is spent reviewing and selecting the best standards (best 
practices, guidelines), and preparing a document, not re-inventing the wheel.

[CODE4LIB] guidance on building archivable website

Long-time listener; rare-time poster.

I just published guidance on building archivable websites:

Please let me know if you have any feedback or questions. Thanks!

Re: [CODE4LIB] Library community web standards (was: LibGuides v2 - Templates and Nav)

2014-10-02 Thread Brad Coffield
So many responses to address! ah!

The LITA support to this idea is lovely to see. Thank you very much.

I agree that code4lib is awesome and that we could potentially create a
document which would gain traction in the wider community BUT I really do
think official support/integration is the best case scenario.


Shaun, http://guidelines.usability.gov/ is a neat site and I'll have to
explore it more, even just for myself. How does this differ from my vision
of what we're discussing (to say nothing of Josh's vision or anyone else's):

1. I think that it makes best sense as far as official
validation/circulation (and for ease of use by all librarian's regardless
of experience) to have a much abbreviated document listing best practices.
And works cited. And maybe an appendix with more information. A sort of
list that the group could agree upon that Well, if a library does these
things they are well along the way to great usability. It wouldn't address
a lot of the nitty gritty details that guidelines.usability.gov does, for
example 13:9 Use Radio Buttons for Mutually Exclusive Selections. That is
an excellent point but TMI for the document I'm describing.

1a. This document would be succinct enough that managing it would be easy.
We need to have something easy to update or it risks becoming old and
useless.

1b. I really like the point made by Christina about not re-inventing the
wheel. And this is exactly where I'm coming from. Yes, there's a ton of
great UX stuff out on the web but what would be a great service to
libraryland would be for a group of knowledgeable librarians to come
together and do all that research work and present everyone with a
simplified 'wheel' for general use.

2. But I'm picturing a lot beyond this. Some sort of website (wiki,
whatever) where library people are able to pool knowledge and resources.
Best practices with libguides. Libguides customizations. I recently did a
complete makeover on our Illiad site - I could share info/steps on how I
did that, for example. People could share useful scripts etc. etc.

The first document would primarily/exclusively be general web best
practices but the second thing - that would go beyond.

Just my thinking. I'm game to help whatever ends up taking shape :)

For checksums for ensuring archival integrity, are cryptographic flaws

_malicious_ changes to files?  I honestly don't know. (But in most systems, I'd 
guess anyone who had access to maliciously change the file would also have 
access to maliciously change the checksum!)

Rot13 is not suitable as a checksum for ensuring archival integrity however, 
because it's output is no smaller than it's input, which is kind of what you're

Checksums can be kept separate (tripwire style).
For JHU archiving, the use of MD5 would give false positives for duplicate
detection.

There is no reason to use a bad cryptographic hash. Use a fast hash, or use
a safe hash.
