The US Web Design System's usability guidance on pagination is very thorough. Some brief highlights:

• Wrap the list in <nav> and use an unordered list for individual items. The <nav> tag should have an aria-label attribute, and the label should serve to distinguish this from the main navigation menu.
• User aria-current="page" on the current page link. Do not write the current page as plain text without a link; this breaks the ARIA labeling pattern.
• On each page number link, use aria-label="page [N]" to prefix the numeric page number with the word "page" (that is, do not allow the page numbers to be read as a sequence of numbers without context)
• Use aria-label="last page, page [N]" on the link to the last page
• Always show the complete number of items in the paged set ("Search results 1-10 of 73"). This should be part of the pagination component itself even if it is also announced elsewhere.
