Haven't we talked about this before, as a profession? Haven't we already improved our websites? Yes, we've talked about it, and some libraries have improved their websites. However, some have not kept up with those improvements and those sites are out of date and not accessible to those with vision impairments.
Is you website content using copyrighted materials?
Sabrina did not touch upon copyright, because her efforts were focused on how websites are structured. However, as you're reading her report and looking at your website, now would be a good time to review your graphics. Are you using graphics which you created? Are you using works with an appropriate Creative Commons license? Are you using works in the public domain? Are you using works where you have received written permission from the creator? If you find works on your site that cause you to answer "no" to any of those questions, now would be a good time to remove them.
Review your website regularly
Is your website up to date and using current technologies? That is a question which you need to ask yourself regularly. I would suggest that you review your site yearly, at least, with more frequently reviews being more useful. Do not let your website get so out of date that updating its structure, content, or technology requires more time or money than you can give.
