When revisiting Pinterest a few weeks ago, I noted an academic library - Valencia College West - pinning selected LibGuides to their boards. Yesterday I spent a bit of time tweaking images pinned to the IRC & LibGuides board, in some cases adding QR codes to pages with limited pin-able images, to better reflect the content. What I did not notice until editing a guide this morning was that Springshare has added Pinterest to the Bookmark & Share menu (see below).
When selected, the Pinterest icon provides users with images from the guide that are available to pin; even better, it's possible to pin the main LibGuide page and/or individual tabs/pages within guides. Yes, it is still possible to use an installed Pin it button, but if students are using a lab or classroom computer (sans Pinterest) they may not be able to install to their browser. LibGuides facilitates Pinterest use immediately; students can pin after instruction sessions, directly from LMS embedded course guides, and while perusing the library's LibGuide collection.
Kudos to Springshare, they consistently keep LibGuides up-to-date for librarians and users.
